How to Find Out Which Replacement Wheel Bearings Needed for 1999 Bayliner Single Axle Boat Trailer


Trying to find the right size wheel bearings for a 1999 Bayliner trailer single axle


Expert Reply:

To get replacement wheel bearings, you'll need to pull one of your hubs and get the reference numbers off the inner and outer wheel bearings. I'll also need the diameter of the spindle surface where the grease seal rides. Unfortunately, I don't have any reference material that would tell me which wheel bearings your boat trailer was equipped with.

If you cannot make out the bearing reference numbers, use a digital caliper to measure the inside diameter of the inner and outer bearing. This measurement needs to be accurate to the thousandth of an inch, so a ruler or tape measure won't be accurate enough.

If you could reply with this information, I'd be happy to recommend replacements.
