Rear suspension skip?

[LumpyVR4]

Just wondering if anyone can tell me why when I push around tight corners the rear end wants to skip around it like the car has a spool? I don't know if the rear end is LSD or not, but seeing as it's been fitted with a 4 bolt I'm guessing it might be.

Sounds like a miss matched front and rear ratio or a welded centre diff.
Mine is welded and the inside tyre skips like a rwd with a really tight LSD in it.
Has it done this for a while or just recently?

Had the car for abour 4 months. Done it since I've had it, whenever I really fling it in. I don't feel it in wider corners under power, only 90 degree stuff.

That's fairly normal for a tight LSD, if it's locked you'll be able to tell on opposite lock when the back kicks out, if you back off it will act like you pulled the handbrake on and be a bit of an animal. How bad is the skipping? does it happen on low power, i.e. just pulling into a servo with a bit of a turn? If so, it could well be locked.

This is just from my experience, I had a PP rx7 locked, (like a 2 way lsd) but have had several 4x4s with tight lsds and they skipped as well but acted differently when backing off. I did note though that the skipping happened a lot with the 4x4 ute with the ally tray a lot more. I'm sure others will have some more accurate ways of telling though.

Actually, now I think about it, if you jack up one side of the car and have one side off the ground, in neutral, if you try to turn the off ground wheels, and you can move the rear around it's lsd, if not, locked. I believe that's a definitive way to tell. Lsds need even weight distribution to put even amounts of torque down. I'm not sure if it works the same way on AWD, but it should tell you.

I knew it had a mechanical lsd owner before you was suppose to swap with my viscous 4bolt

Damn you dave!
