How to Find Correct Replacement Trailer Bearings by Measuring

Question:

I have an older trailer that the bearing went bad on. Im struggling to find the proper bearings to replace. The 1 1/16 bearinf fits the main shaft. But the 1 1/4 is too big for the step up where the rear bearing sits. Any ideas on this? Its an older trailer with 5 bolt hub. For a jon boat. Thank you!

While I wouldn't know off-hand what bearings your trailer needs, I can point you in the right direction. Since you can't see the bearing number stamped directly on them, you'll need to use a digital caliper and measure your spindle where the bearings ride, like in the photo I added.

For example, if you measured and found the spindle measured 1.063" you would need Bearing # L44649.

I have added a link below to our entire selection of bearings for you once you find this info, and you can sort through them by measurement.
