      so i'm in the middle of this decent build i guess you could say
      and i had purchased a quaiif lsd for my vr6 transmission..
      i was wondering if anybody knew the torque specs and anything else important about installing these....
      or even if somebody is nice enough to have made up some sort of procedure i could use.
      thousand thank yous if you can help this lost soul.

      I didn't see this thread... I did do a write-up on the 02A preload specs, but don't have any pics of it hosted or anything...
      Even though it is a bit late, here is a copy for future use:
      Input shaft -
      -Install bearing into trans housing without shim
      -Install bearing into clutch housing without shim
      -Install input shaft into clutch housing, then install trans housing, tighten bolts to 18 ft-lb + 1/4 turn
      -Install measuring fixture, rotate shaft to settle bearings, zero dial with 1mm preload
      -Measure shaft play recorded on dial
      From there you take the recorded play and look at a table of results and corresponding shim sizes. The list is fairly long, so if you need to know a shim size for a certain amount of play, let me know, and I can find out for you. Chances are though, I'd guess, that the shims in the box now will bring you back to spec when just replacing the bearings. It is when you swap case parts or shafts that the preload really needs checked closely.
      When it is all installed again with the proper shim (or the shims you removed form the case in the order you found them), the play is checked again, and you want a minimum play of 0.01mm (0.0004") and a maximum of 0.09mm (0.0035").
      If the bearing play cannot be measured, but there is perceptible input shaft play and the input shaft turns freely, the adjustment is acceptable.
      -Turning torque should be a max of 1.8 inch-pounds
      Output shaft -
      The procedure looks to be the same as for the 020, so that is covered on my site. The only changes look to be the bearing clamping plate bolt torque, for the 02A it is 18 ft-lbs + 1/4 turn; and the final turning torque of the shaft with new bearings....your 02A should be 12-16 inch-pounds of turning torque..
      Install the small bearing and 0.65mm shim, don't rotate shaft to settle bearings, measure play, add play, 0.65mm shim, and a preload constant of 0.20mm to get final shim size. They look to use the same 020 shims and part numbers, so those can be found on my site too.
      Diff Carrier -
      -Install both bearings without shims
      -Install diff in clutch housing
      -Install trans housing, and 5 bolts, tighten to 18 ft-lbs
      -Install dial, don't rotate shaft to settle bearings, measure play
      -Add measured play with constant preload value of 0.40mm to get correct shim size
      -Install shim under bearing in trans housing
      -Lube bearings with trans fluid, measure turning torque, spec values on new bearings should be between 11-29 inch-pounds


      02J specs are the same as the 02A, but VW doesn't offer any turning torque values for the 02J. I would use the 02A turning torque specs for the 02J trans.
