Question:

I have a trailer I purchased used and need to replace the bearings. Im finding a L68149 for the inner bearing and a L44643 as the outer. Would this be correct or possibly someone replaced with the wrong outer bearing? Would this be a #3500 axle?

Expert Reply:

The outer bearing you have, # L44643, is very close in size to bearing # L44649. These two bearings fit different size spindles. So in other words the larger L44649 bearing would be very loose on the spindle that normally takes the L44643. Measure the diameter of the spindle where the outer bearing sits using some digital or dial calipers. If the measurement is 1 inch then L44643 that you have is correct.

This bearing is typically found on 2,000 pound axles but not 3,500 pound axles.

We do not have a bearing kit that contains L44643 and L68149 so you will need to get the races, if needed, and seal separately. The seals associated with an L68149 bearing are 10-19 seals, # RG06-050. The Replacement Race for L68149 Bearing is # L68111 and the Replacement Race for L44643 is # L44610.
