Video Transcript for TruRyde E-Z Lube Grease Caps Plug Review

Hey everybody, Ryan here at etrailer. Today we're gonna be checking out the true ride plugs for EZ Lube grease caps. So right off the bat you're probably wondering are these actually gonna fit my trailer And as long as you have the EZ Lube grease caps chances are really good they will. There are a bunch of different manufacturers that make these caps but generally speaking they're all gonna have the same size opening there. So if you pop this one out, like I said majority of them are gonna be the same. So 1.18 size opening.

So if you're unsure, you can measure that and figure that out really. And the whole point of the cap, you know the grease cap and this plug, is allow to you to pop that out like I just did. Get your grease gun in there and lube up all of your parts inside of there with ease. And then, you know, obviously you don't wanna leave that exposed. So the cap will pop back into place.

And these things are really tight too. So I feel like they do a decent job of keeping everything sealed up. To me this is just one of these small parts. It's just good to keep, you know, replaced every now and again. What happens over time They just wear out, you know what I mean They get sun faded, kind of start to dry rot.

You know, if you're in and out of the water with em, and this is a good example of one that's several years old. It's started to dry rot, try to push it in place, and the center of it just pushed through. So, you know, if you're cap and everything's still in good shape, you can get away with just get the the replacement plugs like this one here that way put it in, keep everything sealed. And that way, you know, you don't end up chewing your bearings up, getting dirt and everything else inside of there. And I was replacing one, I would probably just replace 'em all.

You know, it's one of those small things to just, just knock 'em all out. Like that's just me. And I mean, you know, the type of stuff happens. Like I said, they just wear out, you grease 'em forget to put 'em back in. Whatever the case may be at the very least, there's an option available that you can grab these and get fixed back up. The plug does feel like it's made from some type of rubber, pretty thick. Like I said, I feel like it should hold up for quite some time. That one I just had was super old. So I got a lot of life out of it. But other than that though, I mean, at the end of the day you know, that's really about it. Regardless if you need these, or let's say, even if you're looking for the whole whole deal, you need the cap as well. Tons of different options available here at etrailer. So regardless on the small ins and outs that you need, we should be able to get you covered. And that'll finish up our look at of the true ride plugs for the EZ Lube grease caps..

Grease Cap Plug for E-Z Lube Grease Caps - Qty 2 - RG04-010

Average Customer Rating:  4.9 out of 5 stars   (1033 Customer Reviews)


I tried this product for an aviation application. I own a DHC-2 Beaver aircraft that has a tail wheel axle that is 1.125 inch ID. I wanted an end cap that was removable because the axle tube is used to steer the aircraft with a hand held bar during some ground movement. So far the rubber cap seems to work. It has remained on during several flights. It is easy to remove and insert. The only problem may occur if the cap mounting area of the axle become oily or greasy which may allow the cap to slip off. It seems to need a friction fit to stay on.

Same as described above.

Not all my order was delivered. I ordered 4 sets of ez lube dust caps. They only sent 2 sets. Online the order tracker showed the order had been changed to 2 sets. So someone thought thats is what i needed, despite the order clearly being for 4. I've got multiple trailers these are used on and they go bad over time. The brakes are yet to be installed, but they look good out of the box.

I will have our customer service team reach out to you. I do see that four of part # RG04-010

were ordered which would mean that you would receive eight plugs in total.

I have always found etrailer excellent to work with. Not only do they offer a wide range of products, but personal interaction is available and always helpful. It is tragic that this is a thing today, but the availability of a live human being that actually gives a s$%t about your needs is increasingly rate. Etrailer still offers this and they should be recognized and rewarded for it in my opinion!


Purchased bearing races, tapered roller bearings, seals and dust cap to have for spares for our 2012 Catalina Santara 281BHS travel trailer. Quality products .


The product is exactly what I needed. I was most surprised with the speed that my grease caps were shipped. I ordered them and about an hour later I received and email showing that my items had shipped!


Exactly same as original equipment. Great product and price.

Due to high mileage use of trailer, the hubs are greased every 3 months. The caps are doing great.

Worked perfectly. Fit perfectly. Have held-up on a light trailer for multiple trips.


I've used eTrailer before and they've always had what I needed and my CSR - Ashley E. has been very helpful. Product is what I needed, shipping was on time, could not ask for better service

They have started to leak some but I have found that you need to replace them on a yearly basis as they dry rot and crack...No problems tho after replacing them...

I bought these against future need. I was taking the trailer on a long trip to from Tennessee to Minnesota and ending in Pennsylvania. Turned out I didn't need them (or the bearings bought for the same reason), but It was reassuring to have them.


This is the second time I have ordered items from etrailer and am extremely pleased with the way sales staff assisted me then and now. The sales staff member assisting me with the order of grease cap plugs was Mariah A. She was great. I received my order as ordered on November 2nd,2020 and did the simple install right away on my ATV trailer. I will definitely do business with etrailer again. Thanks again Mariah A.

The grease plugs are performing as expected.I am very satisfied with this product.
Louis R - 11/04/2021


Product was exactly what I was looking for. E trailer shipping response was exceptional.


These are the caps that get removed to pump grease into an Ultra-lube hub. Perfect fit on my trailer with AL-KO 8490 axles and 10x2.25 brakes. Very nice price for a product that can be hard to find locally.
I can't prove it, but my research suggests these cross reference to:
+ 85-10
+ AL KO #568067
+ Hayes #09213611
+ TruRyde RG01-010
+ Dexter 085-001-00


I bought these mainly to take advantage of the free shipping my purchase of the cargo rack earned me.


These do wear out but are very easily swapped out. Its great to be able to replace them so easily through etrailer!


I have ordered things from etrailer in the past and never had an issue. This was no exception. These caps were just what I needed and they came in a timely fashion. I will continue to shop here in the future.


Perfect fit for the bearing hubs of my Magic Tilt trailer that carries my Boston Whaler Super Sport 130.


Grease caps - fit, work as designed


only recieved one packaging is not very good I do not have time to be on hold to try and get another

Sorry about that Rick! I sent your information to customer service and they should be reaching out to you shortly.

Appreciate the prompt service but I guess I messed up on my order. I got two bearings that were the same size. My hub has a bigger inner bearing and seal.

You will need to know both the inner and outer bearing numbers. These numbers can be found stamped on the bearings themselves or you can use a digital caliper such as item # PTW80157
4" Carbon Fiber Digital Caliper
to measure your spindle to the thousandths of an inch at the seal, inner bearing and outer bearing.

Richard - 09/12/2021


Exactly what I needed. Old cap was worn and a crack. etrailer product and service has never let me down.


Fit perfect on my 1.18" hubs. seems good quality hard rubber material


Perfect fit. Does what it is supposed to do. I put these on a 1988 Bass Tracker boat trailer.


I cannot honestly give these a good rating as I cleaned up my old ones and will be putting them back into service. While the rubber on these is soft and pliable compared to the original equipment, the tolerances are all wrong to be able to get a snug seal. The groove in the seal that fits over the sheet metal cap is too wide in the first place, something like 1/16" with the metal being probably half that. Second thing is the hole is slightly larger then the center of the rubber when it is installed meaning this plug does not make a tight seal, my old stiff ones make a tighter seal and will be reused. Also, the part of the rubber plug in the inside has a much smaller lip the catch the metal then the old ones which probably makes it easier to get off and put back on but also means it can fall off much easier as the tolerances are such that it moves around and does not seal tight. In my experience I cannot recommend these.

Nothing has changed, my opinion is still the same and they still sit in a parts bin unused solely to be used as backup in case of emergency.
