Hi Joe,
Have you ever come across the problem I have?
The upper inner pivots freely but doesn't take grease well. With a lot of squeezing on the grease gun it comes through and out of the little rubber seal, but only with a lot of pressure behind it. Moving the arm is then difficult because the grease is completely filling the threaded bushing and won't compress at all. With a few pumps up and down it gradually frees off. The other upper wishbone takes the grease really well, easy to pump and comes straight through.
To clarify I have my subframe off the car without stub axles fitted, hence I can pivot the wishbones by hand.
If there is anything to try, now is the time before I refit the subframe to the car.
Regards
Peter
