Control Arm(s) cause BANG??! Audi 90

Can problems with control arm(s) cause a bang noise off the line, or when going in reverse.. but only from a complete stop .. but mostly only in cold damp weather... and why would cold damp weather aggravate
the problem. I swear I can actually "feel" something when this noise happens... and its loud too
THanks

Erik, It's possible that the control arm is going - although a more likely culprit may be a cv joint, strut bearing, if it's a quattro, you may be in need of a u-joint. The temperature dependence may be due to the cold making old, thick grease even thicker. I had a similar problem shortly after I got my 5ktq - there was a banging under the floor at the driver's feet (LHD car - not UK RHD) - turned out to be the failure of the engine and transmission mounts on the left side - the transmission was slamming the underside of the car when accelerating. R&R was fairly easy on the 5ktq - don't know about on a 90. Cheers!
