Bearing Buddy?

I thought they would be good and they did work for awhile. But found that I overheated the grease when stopped in traffic jam and grease leaked out then made a mess. That was in late 80's.

Then somebody said they have improved them since then, so???

But I wouldn't put them on again. Gives a good chance to look at everything when your packing bearings (hockey pucks, brakes etc)

Just me, you might like them???
