Torsens don't need special LSD oil like other types of LSD. A good quality synthetic gear oil is what you want.

ok thanx mark

now i have another question i have gone to the trouble of fitting it. but there is something wrong with it when i turn corners slowly it seems to be locked up like a mini spool. i wouldent think thats normal.
i removed only the rear cover be for i fitted it
and it looked ok no metal in the bottom and no chipped teeth. it dosent make any noise when driving strait.
any ideas
thanx peter

Thats what I get with a Torsen II type diff, it's perfectly normal for them. Don't know about type I diffs.

I don't think type II's ever came out in a Soarer, except the 40 series. they were in the later (post'96??) Supras and Aristos.

Maybe that's the reason they're called "limited slip". They always slip a little.

I never had the problem on my SVX. I don't think it was a Torsen though.

A Torsen, or Torque Sensitive diff, will lock up when ever torque is applied to it.

ie, if you accelerate, and turn at the same time, it senses to torque applied to it, and locks.

If you back off, and coast around the corner, it will unlock, and go into freewheel mode.




A clutch LSD however, is ALWAYS locked, until the want for one wheel to turn less/more than the other overcomes the strength of the spring making it LSD.

Unless it's a Torsen II which has both. Type I Torsen is a torque multiplier so if one wheel is completely unloaded it won't drive as zero times whatever is still zero. Torsen II overcomes this with a clutch pack.

i am about to remove the diff to have it checked.
from wat i thought i knew about diffs lsd and torsen, have been confirmed by all of your replies.

so thanx for that

from wat i can tell the diff is not unlocking
as i was reversing into the garage with the car only
in idle my dad saw the left rear wheel jerk around
and spin the opposite way hence the bang and shake through the car.

i always thought when they are worn that it
cant hold the pressure on both wheel, or is that not the case with the torsen.

Peter, "wat" should be "what". If you were talking power, it could also be "watt" but not in this context.

From what I've learnt about Torsen's, they don't wear out.
They either work perfectly, or they are broken, there is no inbetween.

Whether you can rebuild them, or just replace the centre, I don't know.

Where did you get this info about a clutch pack?

Manny, I think Neil told me that. there is certainly something that gives the Torsen II different characteristics to Torsen I.
