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.

to do it.  Leakdown tells you how much air you're losing, and
where some of it is going.  If it's going both to the IM and the
