Video Transcript for All You Need to Know About the Grease Seal

Today we're going to take a look at the double lip grease seal for the unique axles with the number 84 spindle. This is for a quantity of one. This will replace worn or damaged grease seals to help maintain optimal performance of your bearings. This uses a double lip seal which is an upgrade from a single lip seal. The double lip seal, you can tell if you feel the rubber edge of it, you'll feel the two lips there and the other way is if you pull back that rubber portion, if you'll notice, there's a reinforcing spring behind the lip which puts pressure on the lips. That does a better job of retaining grease inside your hub and keeping water and road grime out of your bearings. A few specs on this, the inner diameter, the inside diameter is 1.688.

The outer diameter is 2.332". This is designed to fit unique axles with the number 84 spindles. This is for quantity of one seal. The last thing is, is on the product page of this part number there is a chart and that will cross reference part numbers of other brands of seals that will match this seal. That should do it for the review of the double lip grease seal for unique axles with the number 84 spindle, quantity of one..

Fair prices, efficient ordering and transparent shipping. I would order from etrailer again!



by:

Trailer is being pulled out of state, needed the seals quickly. etrailer came through. Thank you



by:

Reliable and quick shipping, including tracking info., good prices. A great back-up company to deal with when our local parts companies can't fill the material requests.Seems like double lip, spring loaded seals are always tough to get. For marine applications they perform better. Highly recommend them. Great website, with good information and products. You know when you buy something from these folks, it's going to make it to the door. Thanks



by:

It's difficult to find the right grease seals. Fortunately, this site is better than any other. Shipped quick and all looks good.



by:

They had a hard to find hub for an old boat trailer axle. The seal was missing from the package, they wasted no time getting me what I needed.

I would buy from them again!



by:

These arrived faster than I could have expected. Quality looks good. They fit the UFP oil bath hubs on my Ranger Trail just fine. I had tried the name brand parts suppliers and a couple of trailer specialists in Jax, Fl. and they all thought I didn't know what I was talking about. One place could have ordered seals for $10.00 each. Thanks Etrailer. I have already recommended you to a friend.

I sold that boat and trailer last fall. No problems related to using your products. Ill go to you first on any future projects and recommend to friends.Thanks, Steve



by:

Right part, delivered quickly (a few days earlier than originally estimated) at a fair price. I love ordering from trailer.



by:

If you have UFP hubs on your boat trailer, these are the seals you need. Slightly smaller than standard 3500 lb axle hubs.

As always etrailer was fast and provided great service.

No issues after 1 year. Still holding up great!



by:

These bearing seals install and work great! They were definitely oddballs--I couldn't find them anywhere else like Northern Tool, or Academy. In fact, twice, I bought the wrong set with the wrong advice from the store aids because they said, "It common, so it should work". Turns out, not so common after all. There's when I found etrailer...and glad I did!

Thank you!

Great! Boat Trailer glides like a champ with no leaks of grease or water in or out!

Quick Delivery

First I would like to say that in my opinion the replacement hub is much better than the original because it is made from a solid casting, as opposed the the 3 piece original. Everything was machined well and fit exactly as expected. Not only would I recommend this product but I have to say that just as important as the product is the customer service. Your representative Kate took the time to help me with gathering the information we needed so that she could then search to locate the assembly I needed. She was confident that it would be the correct one and she was right.



by:

Helped me find the correct grease seal. All worked perfect.



by:

I have only driven 100 miles so my review doesn't carry much weight. If given opportunity later I will update. I will say I had confusing and sometimes unpleasant ordering experience until I called and Tommy C. took charge of my dilema as to go with bearing buddy seal kit or a double lip seal. I went with double lip as per Tommy suggestion.

Good, much better than single lip seal. No grease leaking. You have to get double lip seals in my experience for boat trailer

Want to help out the next customer looking for the bearing, cups, and seals for 2000-01 tracker trailstar trailer. 1st you have to dismantle one of the hubs and see what trailstar decided to put in there the day they built it. You will find the rear cups and seals are considered "Special for some reason". Not a problem for etrailer, they have them in stock and the quality is excellent and are exact replacements. The parts I had to order were cup L68110, cup L44610, seal 168233, bearing L68149 and bearing L44649. Oh yeah, customer service should get a 10 star review. I had an issue with shipping co. because of new driver in my area. Etrailer got all up in their business for me and I didn't have to do anything. Customer service also called me the next day to see if everything was delivered and satisfactory. We need more companys like etrailer.com . Excellent!!

After a year and many fishing trips trailering an average of 100 miles per trip, these bearings are still doing good. No hot hubs, bearing noise or other problems.



by:

Excellent experience.The product is of high quality and the order was processed immediately .I will come back to them to buy again.Thanks



by:

Part was exactly what I needed



by:

I got the email notification that the package was delivered before I went to the mailbox.This digital age is amazing. And the delivery was a day ahead of promised.
I haven't installed them yet but I would like to complement
etrailer on the tech support. I have a 19 year old Tracker trailer. Every few years I replace bearings and always have a problem with finding correct parts, It seems the L68149 inner bearing uses 2 different races that are different in size. To make matters worse the existing inner race was not marked with the correct part number. L68111 instead of the correct L68110. I measured bearing sizes several times and was still not certain what was wrong. While chasing down what to order I found the answer in the etrailer FAQ page. Having the exact measurements for the parts really helped. I also found the perfect replacement for the damaged rubber part on the transom saver for the boat. Now when it warms up a few degrees I can get these installed and be ready to go fishing. Thanks, etrailer.

Just got trailer hubs rebult today.
Grease
seals arrived on time and order process was easy.



by:

I got what I ordered...quick. Had a small issue when ordering on line. It can be confusing when checking out to confirm that the correct products and quantities are included in the order. You push the checkout button and hope the confirmation is what you want. Well, in this instance, only one of the pair of seals I wanted was in the order. I ordered on Friday after hours and immediately sent an email to request a correction to add the second item. I called on Saturday and reached the recording to advise I could speak to someone during normal business hours. So I called again Monday morning and was told by Nicki that my order had already been shipped - efficient! Nicki was good enough to waive the shipping for the second seal, and both seals arrived in separate packages the same day. Everything worked out. Thanks etrailer.com. I might suggest that the purchaser have at least some opportunity to revise an order before it ships if the confirmation does not have what was desired. I know the shopping cart page is supposed to provide this opportunity before checkout, but I've occasionally done stuff that doesn't translate to following screens - like in this instance. All in all, I would definitely use etrailer.com again.



by:

The product was great , fit perfectly,Took for ever to arrive 10 days, so I thought I might not have placed the order correctly so I re ordered them, the people at E Trailer caught the mistake and called me to verify that I really wanted two of the same product . So they are on there toes there at E Trailer. Will order from here again, but the shipping was slow. But it could have been the post office fault.



by:

Good price
Quick shipping
Thanks

Seals were a perfect fit for my trailer wheels and they are doing an excellent job keeping the grease in and water out on my boat trailer.

  • Replacement Grease Seal For a Trailer Hub Using LM11949 Outer Bearing and LM67048 Inner Bearing
    If you can send me the diameter of the spindle where the grease seal sits and the diameter of the hub where the seal is pressed onto I can verify if we have the correct seal. Currently I do see we carry 2 hubs which use the Inner Bearing # LM67048 and Outer Bearing # LM11949. First is the Dexter Trailer Idler Hub Assembly for 2,500-lb Axles # DX22XR which uses the Seal # 168233. This seal has an inner diameter of 1.688" and outer diameter of 2.332". The other hub is an Agricultural Hub...

  • Determining The Correct Replacement Grease Seal For A 1996 Ranger Trail Trailer
    Hey Darin, The A24189 part number unfortunately isn't coming back to anything so you would need to measure the inner diameter of the hub where the seal sits to determine the correct replacement. The only grease seal we currently offer with a 1.688" inner diameter is part # 168233, which has a 2.332" outer diameter. If you can let me know the outer diameter I can see if it's something we could get added to our selection. Bearing # L68149 Race # L68110

  • Replacement Boat Trailer Seal for a NOK AD2527E Grease Seal
    The Grease Seal part # 168233 has a double lip so it can be used on a boat trailer and be submersed under water, yes. This is also the correct replacement for the NOK AD2527E Grease Seal that you have now.

  • Replacement Bearings and Seals for Older Trailer
    Thank you for providing the original bearing and seal numbers from your old trailer. These part reference numbers are often the best method for finding replacements, although especially with older trailers often alternate parts may have found their way into the trailer during its lifetime. We do have the bearings # LM67048 and # LM11949 as well as their matching races, parts # LM67010 and # LM11910. Please note that both of these bearings have an application as an OUTER bearing.

  • Recommended Replacement Seal for an NOK AD2527E Oil Seal
    From what I could find out about your NOK AD2527E seal, it will have the exact same inner diameter as the Redline # 168233. It does look like the outer diameter is a little larger on the # 168233, but not by much. So it will be a bit of a tight fit, but will get everything sealed up properly.

  • Replacement Trailer Grease Seal that Inner Diameter 1.688 and Outer Diameter 2.328
    The thickness of the Redline Grease Seal # 168233 seal is 0.38. However, thickness is not always a dimension associated with picking out a suitable replacement seal. Typically it is the outer diameter and the inner bearing for picking out a replacement seal. Based on the NOK number and the dimensions you listed this is a match.

  • Recommended Trailer Hubs With 5 on 5 Inch Bolt Pattern
    We have a few 5 on 5 inch hubs. They are all for 3,500 lb axles and have # L68149 inner bearing with 1.378 inch inner diameter and # L44649 outer bearings with 1.063 inner diameter. I've attached the link to the page of all your options which has both idler hubs like # AKIHUB-550-35-K and electric drum hubs like # AKHD-550-35-K.

  • Wheel Seal With 1.63 ID and 2.375 OD

It's a double lip grease seal that has an Inner diameter of 1.688" and an Outer diameter of 2.332". The # 010-180-00 seal is another seal with an inner diameter of 1.68" and an outer diameter of 2.33" and also is a double lip seal. I know they are not the exact measurements you gave, but that is the closest size seal that we carry. That's also why it's important to measure...

    There are grease seals with inner diameters of 1.687 inches, # 168255TB, or 1.688 inches, # 168233, that would be a better fit. If the outer diameters match the inner hub bore diameter then you can use one of them instead. Seal # 168255TB has an inner diameter of 1.687 inches and outer diameter of 2.561 inches. Seal # 168233 has an inner diameter of 1.688 inches and outer diameter of 2.332 inches. The seals in set # RG06-050 have an outer diameter of 2.565 inches so that would mean #...

  • Bearing Replacement For a 1996 EZ Loader Boat Trailer
    For your 1996 EZ Loader trailer you will need to get the parts individually as we do not have a kit with all the correct parts. Inner Bearing # L68149 Inner Race # L68110 Outer Bearing # L44649 Outer Race # L44610 Grease Seal # 168233 I recommend using LubriMatic LMX Industrial Strength Grease # L11390 for the bearings. Its is highly water insoluble and able to withstand extreme pressures at hot and cold temperatures.

  • Seal Recommendation for Replacing National 473317
    We only have one seal that matches the inner and outer diameter you need and that is the part # 168233 that you referenced. It may not be quite as wide as your current seal but it still will fit the hub and work well. I have attached a photo of the inside of a hub you can check out. In the photo the arrow indicates how the seal is installed on the hub. As you can see the flat side of the seal is flush with the edge on the inside of the hub. It would not need to be pushed past that point.

  • Replacement Boat Trailer Seal for AD2527
    The Grease Seal # 168233 is the correct seal to replace the AD2527. Your seal is an older design that wasn't the greatest hence the reason you don't see it around anymore. The new seal is a double lip seal that make it right for your boat trailer. You can always confirm the hub and spindle measurements for an exact fit. The hub seal diameter is 2.332" and spindle diameter is 1.688". See the picture.

  • Replacement Trailer Grease Seal for an NOK AD2527E Seal on a Boat Mate Trailer
    To replace your NOK AD2527E seal you can use # 168233. It has an inner diameter of 1.688 inches and an outer diameter of 2.332 inches. Based on what I could find on the NOK AD2527E the inner diameter is the same and the outer diameter is 2.328 inches. So it will be a tight fit but no other seal is even close.

    Thanks for reaching out, Michael! In the past we've recommended the Grease Seal # 168233 as a replacement for the AD2527E because it has a 1.688" ID and a 2.332" OD. To replace your L68149 Timken bearing and seal we have the Timken Kit # TMK73VR.

  • How To Determine Correct Replacement for Grease Seal 8752
    The correct way for you to determine the right replacement grease seal for your 8752 is actually by the inner diameter. Seal # 168233 does have a 2.332" outer diameter and a 1.688" inner diameter, which you will need to match in order for this seal to be the correct replacement. You mentioned the "spindle surface diameter" of 1.67 but I am not sure where you measured that from.

    You are correct that for the Kodiak XL ProLube Kit # XLPROLUBE1980KIT the 1.72" is the diameter of where the oil seal rides and would not work for a 1.68" diameter. Oil is often used on higher capacity axles and we do not offer an oil seal that measures 1.68". We do have grease seals with an inner diameter of 1.68", part # 168233; if yours is a grease hub and you are using oil that may be why it is leaking but if the hubs are also full of water that can also cause leaking.

    You would want to go with a double lip seal since your trailer is a boat trailer that will be submerged underwater.
