As soon as I get the wheels back on I am going in for a good leakdown
As for rings, Deves lists them for this application. It is the
rod bearings that seem impossible to get.
btw, I ordered some
new tie rods and so took off my old ones last night. I thought they were
fine but figured I may as well freshen them up since I am in there. Near
as I can tell, at 150K miles the tie rods were good as new. They were
still full of grease, boots were good, no slop. I probably should have
kept them as opposed to the questionable quality of the new ones.
