I just want to be clear on something...you cannot buy the new parts, until you have already taken apart the truck and measured your pins, as their are different sizes, and you can't interchange them. I thought someone had put up a detailed thread on changing?
Anywho....yes..cup, steel washer, brass thrust washer and then steel washer and cup, with good quality grease in between IMO, and the thin shim under all of that, only if needed of course. They should be almost hard to turn to start with, and few turns under pressure and that will all go away, but if it's loose and still wiggles after install, then more shims are needed.
