Re: Replacing Rear Arm Bearings

Post by white exec »

One of the problems with the bearings is that they don't fully rotate, and only operate over a small arc, so have to put up with the loading being repeatedly taken by a small part of the track and likely only a very few of the rollers. (The small needle rollers used on the Mini, would be an even worse case, and the toll taken by water ingress/rust on these would be quite serious.)

I think you're right: given 'open' bearings, and if some added lubricant could be 'mobile' (eg oil+grease, or very heavy oil), some regular Citrobics would help move the rollers around a bit more than usual, and hopefully move some of the lubricant around.
