Knocking or banging sound when....

gp56 · #1 (**permalink**) 06-22-07, 10:05 PM

When I make a right turn and, lets say I've completed 90% of the turn, and I accelerate hard I hear a knocking or banging sound coming from underneath the car. It will not do it on left turns or going straight. I can duplicate this every time with aggressive driving as I am completing a right. Any ideas what this could be?

I think you may have some extreme seat creak going on. Search it and you will find the tsb. I just had mine done this week in addition to pinion seal and valve for the diff. Only real issues i've had.

Sounds too much to be a seat creak. Where is it coming from underneath, front or back?

By the way, the seat creak TSB didn't solve mine. Next time in I'll have them look at it.

Its from underneath the car, center forward, hard to pinpoint the exact location. Only occurs when accelerating hard as I'm completing a right turn only.

Exhaust pipe hitting the transmission mount crossover right where the pipes go underneath it. We've fixed a couple already.
