Question:

I have a 5th wheel with 2 5000lb axles, do they use the same bearings as the 6000 lbs axles on 5th w

Expert Reply:

5000lb axles like what is on your Tandem Axle 5th wheel trailer are a little odd in there is a few different outer bearings they can use depending on which hub is installed.

All the hub options use inner bearing # 25580 but the outer bearing could be # LM67048, # 14125A, or # 15123 depending on which hub is used.

The only way to be sure is to remove one of the hubs and look for the bearing stamped in the face of the outer bearing as shown in the included picture of the # L44649. While you have the hub off go ahead and measure the diameter of the spindle where the grease seal rides, as there are two different grease seal options.

If you can tell me which outer bearing your hub uses, and the size of the spindle where the grease seal rides I would be happy to recommend the correct bearing kit for you.
