The 32 has a used 8 inch Ford rear end. I just replaced an axle and both bearings. I can hear whinning above the loud pipes I have on the car. I insulated the #$% out of the car.

I think it is the rear end is there anything I can do besides replacing the chunk to quiten it?????? I put regular gear oil in it.

Could it be something else?? Would a 350 Tubo whine???????
