Spring pans, trunions, and lock washers. I opt for the oem truinons from the TRF, and I need to run the lock washer on to the thrust washer. The part I do not like is that there is no knurling inside the lock washer, so I have to tighten the lock washer up and cut the knurling into it (perhaps I should have used some old ones), but anyways the tighten takes a lot of force and I find that unsettling plus there needs to be some kind of end float on the trunion. One problem I see is when the spring pan is on, the end float would be difficult to obtain because the spring pan pretty much holds everything tight. Any thoughts on this?
