86 4KCSQ Right Rear Sag

[Nicholas Menaker <72074.2716@compuserve.com>]

It's me again.  with an 86 4000 CSQuattro that has a slightly saggin right rear
end.  I have put Boge Turbo gas at all four corners with Eibach springs.  New
Strut mount bearings at the top of each new shock, and new RR lower control arm
bushing, ball joint and trans mount.  Nothing seems to make the RR sag go away.
It is about .75 to 1" lower than the left rear, and I also have a squeaking
shock or spring at that corner when the shock is compressed.  Any thoughts on
the matter would be appreciated.
