Let’s perform wheel bearing maintenance.
The hardest thing on a bearing is grease starvation. The factory bearings don’t have inner seals, so I think they tend to lose grease easily and oxidize quickly.
It’s helpful to measure the distance collar length—it’ll come in handy next time.
Spinning it in this condition is extremely stiff, and it takes time for the bearing to seat properly. Since the collar and seal wear down and the fit changes, we pre-seat the bearing first.
The front uses a non-standard bearing, so we use the factory part. Since it has a single-side seal, we remove and clean a used one, then install it as a double-side sealed bearing.
I thought the photos were pretty noisy, but somehow the ISO had gotten set to 16000—it must have been accidentally changed somewhere.
You can also shrink-fit any rubbing areas. A test ride completes the job.
