rear end jittering??

Its winter here in canada and whenever I'm not spinning, and the tires start to grab, the rear end, especially on the drivers side jitters badly. is this common or is my *** ready to fall on the ground?

thanks

What kind of jitter is this? A mechanical problem jitter, or a tire-grabbing bouncing?

how old are your shocks/struts and springs? I find most 1st gens with the O.E. 17 to 22 year old suspension pieces are just plum wore out. this can cause axle hop which may be what you descibe.

Just my $.02

Rearend trouble

Hey Hotty
I bought my first Rx7 about .5 years ago. It had a problem that sounded like yours It happened mostly when pulling out hard and taking a corner at the same time, even a small turn. I was able to fix it by replacing the rear fluid and adding a addidtive to the rear. I can't remember who made it but boy it sure smelled bad. It came in a small bottle only a few oz. The problem was in the lsd and it was causing it to chatter. I have put about 3 grand on sence then and never had the problem again. Cheap fix. They all should be.

ok, that makes sense, I bought my gsl-se about half a year ago also and have replaced the rear fluids with a lsd approved gear oil, but did not add any additives. thanks serf
