s10 blast diffs
 

my s10's diffs are in a pretty bad way, what are people using to shim them up?
i managed to strip my spur gear as well- thought i hadnt meshed the pinion properly but looks like the shaft that carries the spur is bent:confused:
is this a common thing?

looks like theres a bit of float in bearing,shaft or motor mount,
it just isnt running tru,
