If i let the car sit after a long drive to get a bite to eat or something. Go out after half an hour or so and get back to driving the rear end kinda whines/howls, its not real severe, mainly in 5th and 6th gear.I have established it isnt the trans, just the rear end. Oh yeah i also have a granatelli relocation for the torque arm.

 

While in the throttle out of the throttle, when does it happen or does it happen the whole time?

 

Just really under load or even at cruise. And only when its real hot (i believe)

 

My new gears whine at 50+ mph in 5th and 6th gear if you touch the gas. They whine on decel in the lower gears as well, if you just let off the gas and not take it out of gear
