I've done a decent search around for symptoms of a posi on its way out or totally out, but I'm not convinced.

Yesterday I was leaving work and couple of the guys were yelling for me to spin them up. Of course I obliged but I did a casual rolling-drop clutch and rev dump as I left. When I looked back the right wheel was spinnin up a storm, but I did not look at the left wheel. Of course today I went to inspect what was supposed to be two black streaks but only one was there. So now this has me wondering because I've been to the drag strip a few months back and I would do a quick spin-them-up to clean off the tires before staging. The car would get sideways while doing this so I assume both are spinning. Could it be the fact that I was slightly turning right when pulling out of my work that made only one spin? I also do not here any strange noises except for a slight whine but no clunking of any kind.

I had the fluid changed last year with royal purple oil that has the additive for posi's. At the time, the guy also added in the GM additive. Was this too much additive? Could this cause my issue? Obviously going outside and spinning them up dead straight would solve my question but I'm just curious what everyone thinks.

Not sure, in my experience when they start to get weak, they will slip sometimes and not other times, depending on traction, load, etc I assume. At the track after driving through the water hole, its unlikely it would slip as the tires are nice and wet plenty easy to spin both over....

I would test a couple small marks on good level pavement and go from there.

 

Well when I was at the track I didn't go through the water box, but I'm getting the feeling that its just something I have to go out and try to see whats definitely goin on. Thanks for the reply. Anyone else?

 

I've had that happen to me turning right pulling out of a driveway. I wasn't completely straight when I nailed it and the pass. side wheel did all the spinning. Starting out in a straight line both wheels spin. I was told both wheels have to have a certain amount of load on them for the limited slip to engage.

 

Thats good news =)

 

I'm a 3rd gen guy, only owning a 4th gen breifly back in 97, but could it have something to do with traction control. I can't remember if the 4th gens have that or not. Just a thought.

 

well I don't have traction control. Never really understood why the factory ram air cars didnt have it offered.
