My right rear tire has been spinning when I accelerate with about 3/4 throttle while turning.
It also spun today when launching straight forward on wet roads (light rain).
It would also spin the right rear in second under full throttle and boost.

When it spins it does not seem like there is any power to the front wheels. I say that because the car wasn't accelerating and the revs spiked.

Any ideas on what's wrong??
I never had this problem before I did the conversion, but the rear spider gears were also lockedup ... so...
Any ideas?

My '02 WRX has the following mods:
STi 6-speed MT
CenterForce Dual Friction Disc
Vishnu Flew Up-Pipe
IC Hoses
AccessPort running Stage 1 91Oct
K&N Panel Filter


Thanks all

 

Could be a suspension issue. Such as inner wheel lift while in the turn which is common. Looking at Group N and A cars on tarmac you can see the inside rear tires lift in hard cornering. The fact that it spins though is a sign that the limited slip is keeping the car from being one legged. Your diff's working fine. When you hear growling on the turns then u should be worried.

 

sounds like a dead rear diff
