Great work again.......
Maybe that's why yours is making "noise"? Didn't you get it done at a shop?

At the behest of sleepcounter I looked into ball bearings and while I found numbers similar to what you have posted(albeit in imperial measurements) the end result was....I couldnt find ball bearings in the size that would fit the dimensions of the differential anyway. In other words, it was a dead end.

Quote:
I used the stock shim as a template and simply cut my own shims using a pair of scissors.


The shim that was in the diff already was .20mm. After a bit of trial and error(uninstall races, install races) getting the tension right I settled on an additional .10mm and .06mm shims for a total thickness of .36mm.

Notes. Brass is a softish metal. It was easy to work with and easy to trim. There may be a chance that over time it could compress by a certain degree with the heating and expansion of the transmission. How likely this is I am not sure. I did lean towards the higher side of the torque range of the bearing tension just in case. Still I wonder if brass was a poor choice instead of (the slightly less easy to work with)aluminum or steel. Time will tell.
I have had to pull the diff and reshim it. Although I had set things as per the manual (well...sorta. More shims than recomended) things seem to have shifted back to below spec. I developed a "clunking" in the transmission and believed it to be the diff tension. Upon checking the diff, the breakaway torque was much much lower than the minimum spec. Clearly the soft brass shims had compressed too much. I have now reshimmed the diff to an over-spec tightness(22in/lbs) using stock shims(thanks Rami!) with the assumption that after a few drives things will loosen up a bit and things will fall back into spec. Ill see how this goes.
As of 9/25/08....Transmission has been working excellently after a year of autocrossing.
