1987 34W - Complete list of bearing/race/seal numbers for 12" Dexter Adjust-a-Ride suspension

Post by Razorback »

(I am editing this first post after having found a mixture of 5.2K and 6K axles on our trailer. Everything is the same between the two axles with the exception of the outer bearing and race. I have found a good source for all of the parts, and list them here. I will also add them at the end of this thread, and will see about pinning this list to the Running Gear section:

Grease seal:
Single lip - http://www.dexterpartsonline.com/product/27-361
Double lip - http://www.dexterpartsonline.com/product/10-10

5.2K Bearing kit - http://www.dexterpartsonline.com/product/27-086
6K Bearing kit - http://www.dexterpartsonline.com/product/27-088

Inner Bearing for 5.2K and 6K 25580 - http://www.dexterpartsonline.com/product/25580
Outer Bearing for 5.2K LM67048 - http://www.dexterpartsonline.com/product/27-328
Outer bearing for 6K 15123 - http://www.dexterpartsonline.com/product/27-340

Inner Race 5.2K and 6K 25520 - http://www.dexterpartsonline.com/product/25520
Outer Race 5.2K LM67010 - http://www.dexterpartsonline.com/product/27-329
Outer Race 6K 15245 - http://www.dexterpartsonline.com/product/7800055)

Did some homework yesterday, trying to gather a complete list of bearing/race/seal part numbers for our 1987 34W that has the 12" Dexter Adjust-A-Ride suspension. I have seen this suspension mentioned in brochures as early as 1978, and they used it through the 1988 model year.

I came up with this list. You'll need one set of these for each wheel. After buying a set from O-Reilly (National Bearings parts), I found that RockAuto.com has great pricing on Timken bearings, which I prefer based on years of good-quality products from them. The only thing I will still need to get through O'Reilly is the grease seal.

Inner Bearing = Dexter K71-308 = Timken (and others) 25580; bearing race (or cup) 25520..... I ordered these from RockAuto.com
Outer Bearing = Dexter K71-307 = Timken (and others) LM67048; bearing race (or cup) LM67010..... I ordered these from Rock Auto.com
I also ordered from RockAuto.com a tool kit for removing/replacing the bearing races. Got 5 sets (bearings/races) and the tool kit for about $135, an awesome price! (Remember: I got a set for one wheel locally at O'Reilly, so I only needed to order 5 sets from RockAuto.com)

Grease seal = Dexter K71-305 = Tekonsha 5606..... or, from O'REILLY, National # 413470. They are $17.99 each, but the way they are made leads me to believe that they will be a much better seal.


I hope this helps others, whether you do the work yourself or hire someone to do it.

(7/24/2017 - editing this to add further information and have it all in one post: I found that two of the half-axles on our 1987 Avion 34W were the newer 6K lb axles, as opposed to the original 5.2K lb axles. The inner bearings and races are the same # 25580/25520 and the grease seal is the same, but the outer bearing is # 15123 and race # 15245. Be sure to check yours before ordering your new bearings. Bearing numbers are stamped or laser etched onto the center hub of the bearings. You will need to remove and clean the ones you have to see the numbers. I would also like to remind anyone who is going to do this work: when you raise the trailer, you must support it safely. Do not rely on the jack to keep it up, and DO NOT USE CONCRETE BLOCKS as supports! I like to use 20" pieces of treated 4x4 or 6x6 posts to make a sturdy support)

Received the RockAuto order over the weekend. Still need to get the grease seals from O'Reilly, then make some time to do the work. Also noticed that the rear curb-side tire is toed out, causing wear to that tire. So, I guess I'll get to adjust that axle to fix that.

Thanks for the list. I am going to have to do that as well. Along with new tires. Still running the 7.0 15's that looks like the trailer came with :?

If you'd like, I can take a picture of the invoice that will have the item numbers on it (from RockAuto)

I would greatly appreciate that. Anything to help make the trailers transformation easier is good in my book.

Here is the packing slip for my order. It shows the RockAuto item numbers. I hope to do the work early this week. I'll take pics as I go.

Thanks a bunch, I will be ordering some in the near future. Currently vents and outside doors are the priority though.

For the grease seal, I have found an alternative to the Tekonsha 5606, and from the looks of it, it is a better seal: from O'REILLY, National # 413470. They are $17.99 each, but the way they are made leads me to believe that they will be a much better seal.

When I do the work, I will get a picture of them side by side.

Wow that's an expensive seal! I believe these are the same inner and outer diameter and are double lipped... https://www.etrailer.com/Trailer-Bearin ... 6-090.html

I think the Dexter seals referenced above have an ID of 2.250 and OD of 3.376, whereas those Nationals have an ID of 2.125 and OD of 3.376. It's probably negligible, but I just wanted to mention it.
