Should Removing Trailer Bearing from Spindle be Difficult

Question:

Hi, I’m running into a problem with ing an outer bearing. The trailer I purchased came with an outer bearing that sticks to the spindle. I have to use a gear puller to remove the hub. The spindle measurement for the outer bearing is 1.25. A replacement bearing LM67048 doe not fit on to the spindle. Would the 15123 bearing have a slightly larger ID?

The bearings part number # LM67048 and # 15123 both have the exact same inner diameter of 1.25 inch so one would not fit easier than the other. What is most likely going on is that your spindle needs to be sanded down if it's not perfectly smooth and round or it needs to be replaced. Bearings normally do fit pretty tight but you shouldn't have to use a gear puller to get them off so that's somewhat of a red flag.

For a new spindle that matches what either bearing fits you'd want the part # TRU37FR.
