Discovered that one of my rear bearings was so tight as to be impossible to turn by hand, so ordered a Timken bearing set and set about sorting it out last night. All went to plan, was much easier that I expected, but when putting it back together I discovered the hub nut washer is no longer flat. Ordered a new one, no big deal.
Anyway, I've had a proper look at the washer today, it is concave by about 0.5mm at the edges, but it also has a groove on either face about 5mm in from the edge of the hole, whereas the replacements look completely flat. I can't tell if the grooves are supposed to be there or whether they've been worn in. It looks like the hub was massively over-tightened to remove play from the bearings, which has bent the washer.
Does that sounds like what's happened here?
Everytime I look at a new area on this car I find some dodgy bodge or other!
