Are these roller bearings okay? One is gray, the other muddy

처리 내용

Both bearings show a wear strip - this is normal. The grease that is milky or grey has been contaminated and needs replacing. On my 4*4 I used to clean and repack the bearings then set the play very carefully. They lasted for years with no problems with exactly that middle strip wear pattern. Inspect carefully - any chips or cracks on the rollers means time for replacement.
