Replacement Bearings for Older Trailer with Dexter Hubs

Question:

I need to replace the wheel bearings on an older trailer. The Hub is Dexter 8-258 Bearing race looks to have L44510 Slovakia this all seems so close in specs to L44610? I went to auto parts store today and they were not sure.

The sure-fire method for finding a correct replacement bearing is the part number from the original part. Usually a bearing part number will be stamped into the outer portion (please refer to the linked photo). If this cannot be found you can select a bearing based on a precise measurement of the spindle's journal surface where the bearing rides; this requires a very accurate measurement be taken with a precision digital caliper (again please refer to the photo for the locations on the spindle where you need to measure).

With that information you can use the link provided to select bearings. The left hand margin includes filters that will let you choose the weight rating of your axle and then the bearing dimensions you need to match your spindles.

In some cases we may have a complete kit; otherwise it will be necessary for you to select the individual components.
