Hell all, first time post. BLUF: I have a 120 round trip commute everyday, and I want to increase the performance and gas mileage of my compass. The only thing I have right now is a K&N rechargable air filter. I have 130k+ on her right now, bearings have been changed, brakes last year.
I have a thumping type sound when accelerating somewhat hard from a stop which sounds to be coming from the rear.
It almost sounds like the drive shaft hitting but stops after it shifts.
Anyone have any Idea what this could be?
