Video Transcript for Double-Eye Springs Wet Equalizer Bolt Installation

Hi there trailer owners. Today we're going to be taking a look at Redlines replacement shackle wet bolts. These bolts will make a great replacement for standard bolts or wet bolts if you are performing suspension work here on your equalizers and leaf springs and you find that they're all wore out. Over time your bushings can wear out, and once the bushings start to wear out, play will develop inside which will allow movement of the bolt inside of your suspension components. And that small movement will allow the bolt to travel up and down. And this little bit of movement is going to cause wear on both the bushing and the bolt and over time it will eventually destroy the bushing and it will also make our bolt a smaller diameter with an uneven wear pattern on the inside, so you'll need to replace it when you're putting a new bushing in or else you're still going to have that play from the bolt wear.What's nice about these bolts is that they do have a grease fitting on the end so you can grease your bushings.

Many of your factory suspension setups will have non greasable bolts with bronze bushings. And if you have that combination, those bushings are eventually going to wear out. They need lubrication. So upgrading to these will allow you to lubricate your bushings and your bolt to ensure that they don't seize together and also provide a lubrication coating between the two so we have no metal on metal contact, which greatly reduces the amount of wear.Wherever these bolts are installed, we have bushings in them and these are the design movement point for your suspension system. The bolt will pivot inside of the islet here on our leaf spring.

Same with our equalizer in the center and at the bottom here, all of these components move. And over time they will eventually wear out the bushings on the inside. But being able to lubricate them greatly decreases the amount of wear.What I also like about these bolts as they can be used with any type of bushing, too. If you're going to be using with a bronze bushing, they're great because they will fit in there and you also have a way to lubricate them, but you can also use them with plastic bushings. Many of your plastic bushings are self lubricating, so you don't want to lubricate them because the grease can potentially break down the plastic of those types of bushings

It is a 9/16 diameter bolt. Included with your bolt, you are also going to receive a lock nut, so when you're replacing the bushings on your worn out suspension system, I highly recommend replacing the bolts at the same time. It's going to make the installation easier. Often when you're taking apart your old suspension and you're planning on greasing 00:02:46 those bolts, the threads and things like that can easily get nicked and damaged because you do have to drive out your old hardware. And you can use the nut to help protect it when you're driving it out with a hammer.

But depending on how tightly they are seized inside your suspension system, you may still end up mushrooming the end and needing a replacement anyway. Replacing it with the lubricatable end here is going to further increase the life, so that way once you're done fixing your trailer, you can just keep maintaining it so you don't have to make those repairs down the road.They're fairly easy and straightforward to install. You can pick up as many as you need for however many bushings you're replacing in your suspension system. Let's go ahead and go over the installation together so you can the confidence to do it at home. We'll begin our installation by getting our tires out of the way. We're just working on the back axle for this one. So we don't need to remove our front. But depending on what all you're doing, you may need to remove yours as well. When removing your wheels, you want to make sure you got your trailer supported on the frame by jack stands. So you can use just a regular floor jack to lift it up.Once you've got all your tires out of the way for the area you're going to be working in, we can then start removing the bolts for wherever we have damaged bushings. We recently just had a new equalizer installed here and you can see we've got new bolts and shackles and an equalizer, but the bushings weren't replaced inside of the leaf spring here. So we're going to tackle that as well because we still got a little bit of a clunk noise because that bushing's wore out. To replace the bushings, you just needed to remove the hardware first. So for this particular set up here, the bolts are pressed into these shackles on the head of the bolt side. So we're going to remove both of these nuts and take the two out at the same time.We're going to take our bolts off. The bolt sizes can vary depending on your particular trailer. For ours, we're going to be using a 7/8, and you may or may not need to hold the backside of the bolt when removing these. They are supposed to be stuck inside of here, but over time they do rust and things wear out and they may not be. So it's not a bad idea to put a wrench on the other side to hold it.If we place our floor jack underneath the U bolt on our axle, we can relieve a little bit of pressure on it to make it easier to get the bolts to come out. Now what I'd like to do to get them out is I like to just thread the nuts back on there just a little bit and then tap them out with the hammer. Putting the nuts on it just helps prevent you from damaging your threads when you're tapping on them. And we can just slide it out there and you can see on our equalizer, we've got a brand new bushing in there, but on our trailer here, we've got an old one. And this old one here is so worn out that I can actually just push it out. Now if you we're unable to just slide out your worn out bushing like this, one of the best things to use to take them out as you can use an old bolt.So if we use another bolt that's slightly smaller and just place a flat washer on it, we've got a nice flat solid surface to drive it in. And we know since we're hitting all the way around, we're not going to ding up the outside of our bushing here with our hammer as we're driving it in. So we're just going to hold it in place and we're just going to tap it in with our hammer. A lot of times these tap in pretty easily. Every now and then you got to hit them pretty hard depending upon the rusty condition of your leaf springs.We can now take our new wet bolts and we can slide them into our shackles. Now if your old shackles are all worn out and the holes all wallowed 00:06:53 out, then I would recommend replacing them. We've got replacements here at etrailer, but if they're just a little bit of surface stress on them and the holes are fine, then you're okay. You can just slide your bolts right into them. Once you've got them slid in, we can come over to our bushing here and align them up. It is a bit of a snug fit. Sometimes you need to adjust the jack a little bit. WE're just going to line those up until they slide through.On the other side. Now we can take the other shackle and place it on there and then thread our nuts on. We can now tighten up our nuts. Now what you're going to want to do is hold the backside of your bolt with your wrench, because our bolt does have splines in it and it's going to spline into the inside shackle here, because the head of the bolt here has got those splines. And we don't want it to spin while we're tightening it down because it's going to rip the splines off and prevent it from working like it's supposed to. So we want to hold it steady, and then tighten it down and that will draw the bolts into the shackle and draw them tight together. And I do like to work back and forth with them just a little bit just to make sure that they are going to get pulled in.Once you've got them tightened down, it's always going of you to double check yourself and look here on the backside. You want to make sure the head of the bolt is flush all the way up against the shackle here. Sometimes the splines will prevent the bolt from going all the way in and it's not that it's preventing it from going in, just means you need to tighten it tighter until it draws it all the way flush.We can then go back and lubricate our bushings. Now we're only going to be greasing the bronze bushings, so that's going to be just this top one here on the leaf spring. Now that we've got our wheel back on, we can torque it to the manufacturer specifications and we're ready to hit the road.And that completes our installation of Redlines replacement shackle wet bolts.

As always the customer service is great and the products are as advertised. The website is full of great resource. My issue is with the shipping, more specifically the packing. Heavy items are just placed in a box with very little regard to cushioning or protection. This particular shipment had eight heavy shackle bolts and nuts in a box with hub seals. The seals weren’t in any sort of packaging and could easily have been damaged during transport. Only thing I don’t like about etrailer, terrible packaging.

etrailer has always had great products, excellent service and prompt deliveries. I thought it very odd when I reported a discrepancy with the bolts in the shackle replacement kit I received, that things got mysteriously quiet on that end. But when I ordered the extra bolts I needed, they got here in 2 days, so I'm happy.

The wet bolt kit was great improvement to our trailer suspension and needed as part of replacing worn plastic bushings that came oem on our Forest River trailer.

I bought a set of these bolts to replace the hardware in the triple axle suspension of my toyhauler. I had read about the benefits of a wet bolt kit, and after finding two broken shackle plates on my camper, decided I too needed to be able to properly lubricate the moving parts. These were a perfect fit and replacement for my original bolts. At the time I installed them I hadn't read about orienting the hole in the bolt to the 3 or 9 o'clock to ease pumping grease through them. I put them in at whatever orientation they were in my hand, but had no problem pushing 3 - 4 pumps of chassis grease through the zerk. I was able to observe grease flow out of the spring eyes around every bolt, and all of the zerk fittings stayed firmly in place when I wrestled the grease gun nozzle on and off. There were a few bad reviews about these press on fittings falling out, but I didn't see any evidence of that. I am very pleased with this purchase, and enjoy the peace of mind that comes with knowing I can properly service my suspension and hopefully extend the life of all the components in the system.

I used these "wet" bolts on my leaf spring change out. I ended up using 3 per equalizer since that seems to be the location of most of the movement during axle travel and a friends 5th wheel had 3 installed on the factory set up, so that is what I went with. I painted a yellow mark on the head of the bolt in reference to the grease hole in the shaft, so that I could install them in the direction of "least resistance" when greasing them later, after reading how some guys have to relieve pressure on their trailer in order to get the bolts to take grease. I used Mystik 6 grease mixed with anti seize when putting everything together, then gave them 2 shots of Mystik 6 after installation. (I chose Mystik 6 because we always had good results with that grease when I was in the aircraft industry and it doesn't was out.) I did notice that the grease zerks did allow grease to return out of the fitting which means the spring behind the ball isn't doing its job. That is why I rated them as "good". There are different ways to install these due to the knurled shoulder. If you have access to an impact gun you can just tighten them in with that. Pulls the knurl right in to the shackle. Overall I like the idea of having a suspension that can be greased.

these wet bolts make a huge difference in how my suspension works. No more squeaking, popping and after 10K miles, bolts and bushings look brand new.

The wet bolt and bronze bushing were delivered on time and in perfect condition.

Got the order, box was busted, nuts were missing. Emailed about it. Several emails back and fort each time having to re explain that NUTS were missing. Finally get an email that the replacement SHACKLES were shipped... I give up. We will have to find some nuts somewhere else. Never ordering with etrailer again. Sad

I will have our customer service team reach out to you.

I bought these to go with a set of new leaf springs for a skid-loader-trailer at a concrete company. I don't do their regular maintenance but I do notice fresh grease around the equalizers, so I take that as validation in my theory: "Give the boys a grease zerk and they'll grease it." Very happy with everything that I got from etrailer.com last year. Great pricing for known brands on a site that is so easy to navigate that I now use it as a reference for every trailer repair that I do. Who could ask for more?


Comments
Its music to my ears when I hear concrete guys complaining about grease globs on their perfect shop floor. The trailer is used almost daily and doesnt rattle, creak, squeak or lean. Very, very happy.

Awesome thing to add to Tracker boat trailer to stop squeaking on leaf springs

I ordered 14 bolts, one came with no grease fitting. I am pleased with the speed in which they were delivered, but disappointed that somebody physically counted out 14 bolts and had to have seen one was missing a fitting, but put it in the bag anyways. We installed it regardless since I wasn't sure I would have help later. I called customer service (on a Sunday, which is nice), got a hold of somebody immediately. They are resending one out and said it would take 1-1.5 weeks. It should take me about 30 minutes to reinstall. I will follow up once I receive it.

New springs fit perfectly and we're easy to install. Shipping was really fast. They gave my old camper a which was sagging on one side, a well needed lift. The new equalizer bolts should help keep the springs operating properly for years to come.



- 126B2
by:

The concept is great but the product is poorly made. Two of the four screws lost the grease fitting on the first use. Installation was simple.



- 126B2

The order was shipped and received ahead of scheduled delivery. The customer service was great and I would recommend etrailer for very prompt service and delivery of products.

I really like e trailer and all the people who helped me with my purchase. Your technical advice has been great and the arts department was equally splendid. I have recently placed another order with you and have recommended e trailer to several RVers. I look forward to doing business with you for the foreseeable future.

Attached a before and after picture. Everything fit perfectly. I used a right angle grinder with a cutting wheel to split the old nuts off. Heated the spring eye enough to melt the plastic to drive out the old bolts. Used an 11/16 drill bit to clean out the spring eye, then used a c-clamp to press the bronze bushing in then bolted and torqued everything like the instructions stated.

I had a trailer spring break this summer on the way home from a 2,700 mile trip. Our small luggage trailer just couldn’t take anymore rough roads. One of the springs broke through the centering bolt. The etrailer.com website and Tammie P. came through with replacement springs and accessories. Thank you Tammie P. And trailer.com!

Just replaced all my shackles and equalizers bolts with ones with grease zerts. All bolts were seized And wore badly. Won’t happen again. Priced right, no to keen on sure post but, does keep the shipping low.



- 126B2
by:

Good quality, good value, great price. Installed on Equa Flex equalizers on 5th wheel camper to lubricate brass bushings. Fasteners did the job!



- 126B2
by:

Good bolt. Trailer is now greasable.



- 126B2
by:

Would rather a threaded zerc instead of a press fit zerc but I'm doing good to get them, Threaded stays put better and is easier to replace.



- 126B2
by:

The bolt is perfect, it is and does exactly what it is supposed to do. It was too long for my shackle, it took buying two of these to determine how the measurement for length is made. I know now.



- 126B2
by:

This is a multiple product review. The long bracket are good. The shorter brackets are of the same good quality. The issue is using the short brackets with the shackles. The shorter brackets could be narrower so the shackle line up better with spring and other longer bracket. We used washers to make it align better. The greasing bolts are good, but could be longer. so we could only use 2 of the 6 and had to use normal grade 8 bolts.



- 126B2
by:

The parts arrived soon after I ordered them and all the parts appeared to be for good quality. I installed the parts on my old snowmobile trailer that I was rebuilding. I sometimes use the trailer to haul some heavier loads that were well beyond the rating of the old springs and that took a toll on them. These new 2000 lb spring are working well for these heavier loads. I used the Wet Equalizer Bolts with Locknuts and Grease Zerks to mount the leaf springs to the trailer with heaver duty shackles, they worked well.


Comments
They are working fine. I wanted to go a bit heavier that OEM and they work good for the heavier loads.
