This arrived yesterday. It looks like it came from a freshly slaughtered drivetrain, as it is still dripping blood red diff oil - nice clean diff oil - and the diff looks to be in very good shape. THANKS JIM!

Upgrades or fixes?

Bill Ball

Upgrade for traction purposes. My car is open diff.

mspiegle

aww, can we still expect to see you as a contender at the 2006 Sharktoberfest burnout competition?

Tony

He will have twice the smoke!!

Shark Blood?

Well, I always knew you wouldn't stop with just a supercharger. And with the LSD your shark will do the fishtailing appropriate for the species.

Darien

I want one

Darien,

Have you checked to see if yours has one? My has option 220 and it cuts down on the burn out to approx. 75ft ( 1st and half a 2nd gear). Visually an open differential is a lot more entertaining.

Vilhuer

Did Jim also send pinion shaft or did you split matching pair?

Darien

While the rear end was up, I spun the left wheel and the right spun opposite. It still spins both in 1st and 2nd

Imo000

That’s a good point. The pinion and ring gear should always be kept together as a pair. I would just transfer the original ring to the new dif. and reinstall it.

jyoon

you may have to check clearances for shims, no?

Make sure you get a backlash reading before you take it apart. Then put it together returning it to the same backlash.

Bill Ball

You guys are certainly correct. I was a bit surprised to see the ring gear. Either the tranny (and mated pinion gear) it goes to is trash, or I will send it back to Jim.

This will be my first diff swap. I am aware of shimming, backlash etc. Retaining the original pinion-ring pair and the same diff case seems to obviate all but the shimming for backlash. A few others that have swapped diffs like this say there was no adjustment needed for them.

Bill,
It would be a waste not to send it back but then again they probably have so many that they really don’t care if this set gets scrapped.
