Solid pinion sleeve?
Oh......the car is going to be M6 with either 4.10, 4.30, or 4.56 in the 10 bolt
every time you overload it, it adjusts a little more.
Then your pinion bearings loosen up and the looser
they are, the more play you get. Free play makes for
the possibility of impact rather than constant mesh.
Impact is a tooth killer.
Hard pinion spacer (Ratech) is set up with a stack of
shims and nothing moves from there. So the pinion
depth, pinion end play, gear pattern all stay like you
put them.
Which just means you can concentrate on twisting
off axle ends instead....
