I know this will come as a silly question,but from someone that is learning the very basics about cars its the type of questions you get lol. Anyway ive heard alot about bad wheel bearings,in fact mine might be going bad soon.I know the repair is repacking the bearings.Ok heres my question,is the wheel bearing part of the axle or is it part of the actual wheel that you put the tire on?(when your done laughing and pick yourself off the floor please explain this too me,thanks)![]()
