Question:
I believe I have a BTR 1 1/16inch spindle on a jet ski trailer. Im replacing bearings, races, and seals. Bearings: L44649 Races: L44610 Original seal: 10-9? The spindle had what appears to be a repair sleeve on it which I removed. The OD of this sleeve was 1.5. The OD of the spindle seal mating surface without the sleeve is ~1.46inch . Where can I find the appropriate repair sleeve and seal? Thanks

Hey Jared. It sounds like your jet ski trailer has the Spindle Grease Seal Set for L44649 Inner Bearing and 1.980 Bearing Buddy item # BB60005. What you're talking about is a wear sleeve which is included with this set.
Then you would just need the Replacement Trailer Hub Bearing item # L44649 and the Replacement Race item # L44610.
These parts will take care of one hub. If you have any additional questions go ahead and throw them into the comment box below.

Hey Jared, did the grease seal set with the included wear sleeve fit your jet ski trailer spindle the way you needed? Knowing how it worked could help others trying to match the same bearing and seal setup.
