Posted on the TVR forum but please excuse me asking you good fellows as well:

I'm rebuilding the Spitfire/Vitesse diff on my Vixen.

I have replaced the pinion head bearing and pinion tail bearing but I just cannot get any pre-load. I have removed all the shims (there were 3 when I dismantled it) and torqued it to about 70 foot-lbs but the pinion just spins freely - should be about 16 lb-inch resistance.

Anyone any ideas ??

Well, no bright ideas from anyone so far...

This is a mystery to me because I would have thought the new bearing cones would have sat higher in their raceways than old ones so more shims would be needed.

It would appear the new cones are sitting lower but even though I have removed all shims there's no pre-load.

Looks like the only solution is to reduce the length of the solid spacer by a few though.

Looks like a pleasant evening with a sheet of wet and dry on a sheet of glass coming up.....
