Wheel bearing replacement - What can happen if job done wrong?
OK, so I replaced bearings on left front side. Perhaps I should have my mechanic done it, but I am growing frustrated with him for number of reasons... So I decided to have him only for stuff that i can not handle.
Back to the bearings - the hardest part was to get inner race out of the hub. I didn't have a puller and used a punch and mallet to drive it from inner side of the hub. Used the old race as a punch to drive new one. Seemed it set right. One thing I am not sure about is if I put the hub back on the knuckle properly. I whacked it couple of times with rubber mallet to make the seal set on the knuckle, then tightened the retention nut while rotating the hub counterclockwise, untill it was hard to rotate the hub. Than I relaxed the nut by one third of turn. I am not sure if I relaxed the bearing, as Haynes describes. It says to whack the kingpin couple of times with mallet (which I did), but not sure if it got relaxed... Calipers sit properly. So should I expect my wheel to fall apart is something went wrong?... Thank you
