I have the 9 bolt with 3.27 gears and lately I've noticed traction is limited. I can't hook at the track like I used too. I've got a few runs on video and notice in the waterbox the lesft side gets spinning first and then the passenger goes.

Sometimes from a dead stop on the street full throttle launches only get the drivers side going.

I fear the worst case is my posi unit is going out on me. Do they do this when they are going or do they either work or not work?
