LSD Help

[Christopherrr]

Guys,

I'm working on a 01 z28 with a Torsen Rearend... I and my tech overlooked the whole unit and the rear looks fine. The ring and pinion are good. We're not too familiar with Torsen setups.

Anywho, here's what's happening. In the air, when you turn the wheels forward, the rotate opposite of each other, when you rotate them in reverse they rotate opposite of each other and then if you rotote them forward again, it locks up and both tires rotate forward...is this normal for a Torsen unit? It looks like one of teh worm gears is catching... would worn axle clips cause the catching?

The problem is that this thing locks up intermitantely...strange. My shop is only familiar with Auburns and LSD with clutches.

yeah, I don't really understand them either- they don't behave like the Auburn and Eaton units with clutches I have played around with on lifts-

They are torque-biasing or torque sensing- I think that means that they need to have a load applied on one side, and the torque ratio is how much more force the other side will receive- if neither side is loaded, it seems like they just act like an open diff-

The only reliable way to test if they are working is go do some burn-outs- at least on soil if not pavement- under a hard load condition, both wheels should be spinning

No biggy...the owner wants to throw in an Auburn unit anyways.

Thanks Willy.
