Subject: Viscous LSD Identification and repair

Date: 	Fri, 2 May 1997 01:00:17 -0500



Its been asked before, but I've never seen a definitive answer...



A friend has a spare diff, not in a car, that he thinks is the viscose   

LSD from a '90.

Does it have any identifying part number, or feature (i.e.. twist this,   

watch that) that will confirm this easily.



Do these items have a common failure. It was removed from his car by the   

dealer and replaced with a new one, before sale, because it made a noise.   

Is it totally shagged, or can I expect to replace a couple of bearings   

and have an LSD in my car?



I know the torsen is the way to go, but surely a viscous is better than   

open right?  I've been doing gymkhanas on grass and loving it. I expect   

this should help get my times down a bit eh?  (mucho wheelspin)



Thanks for any advice...



Fletch,



Red '90
