Default Torsen question...

When the 7.5 factory ('01-'02) limited slip starts to work off-and-on, is there any parts that can be replaced to make them work properly again? Any re-build parts available? Are the Eaton limited-slip units (7.5) noticeably better? Thanks. WJ

Change the fluid to a synthetic, that should take care of it.

There are no "designed" wear parts in the Torsen, and the spiral gears only turn when going around corners, so there is little chance they have worn significantly.

The gears need the right lubricant to deliver the right friction ratio to the gears.

Mine was so worn you could see the cuts in them and pits all over the place so they can wear down.

Damn, do you drive in circles all the time ??

How many miles, what kind of fluid ?

All the ones I have see show imperceptible wear, even after 50-70,000 miles

Hmmm, I did remove the synthetic when I installed the T/A cover and installed regular dino oil, along w/a bottle of GM additive...only 5,500 miles on mine and it only does it occasionally on my burnout w/the slicks bolted on. I also pre-load my rear on the right w/a airbag in the coil...Could too much pre-load have anything to do w/it? Thanks TRex.. WJ

Preload is a good thing, not bad. I think it is the oil.

Question

Since we're on a torsen question, are the slits on the torsen suppose to be there or did it get put on there from hard driving? The first pic is the new torsen. The second one is a stock 10 bolt w/ 3.42 gears

The Auburn Gear Pro Series Differential that I just bought and used for 8 drag passes over the past two weeks is a nice piece. 12.27 @ 110 on a 95 carbed LT1 (iron headed caddy motor/ TH350 conversion in a 1986 coupe) in the Hattiesburg heat and humidity last night (4-29-05). It helped cut 1.70 60' times.

p.s. the instructions on the the auburn gear was to use with dino oil only with their traction lock solution. ABSOLUTELY NO SYNTHETIC OIL.
