Took a look at my HB and i noticed that it is wobbling pretty bad. So i read up on how to replace it and while i think i know, i cant find like a complete how to. I read about a key of some sort and then there is a seal and I cant find any guide that explains all that in one. If anyone can find a complete how to on HB replacement that would be great. I have a 2000 4.0, and also is the dorman replacement any good? Thanks!
