Gears & Axles - limited slip???

Ok im not sure if it goes here but I have a 1990 chevy 1500 with a 2000 Ls1 in her =-)

My question is... I have an aftermarket limited slip rear end and For some reason it seems to just act like a normal differential. When I try and test it by trying to spin the tires alittle the right tire spins and the left doesnt even try to budge any causes ??? Thanks guys

Mine does the same at the track on a burnout. Only the right tire will spin. I was told that the clutches in the rear are shot. Anybody else?

What can I possibly do to fix it?

No one??

if it's a rebuildable limited slip, get a limited slip rebuild kit. i know you can get that stuff for the eaton posi. not sure about others.
