Hi, I'm hoping for some help with a knocking noise that comes from the right front suspension of my modified 70 911under somewhat
inconsistent circumstances. I bought the car as it sits fairly recently, it has gas charged Koni's and an aftermarket weltmeister torsion bar. When
the knock occurs, it is as if someone struck the shock tower with a metal mallet, loud and painful. But, it does not always happen and it does not
always
happen when the corner is already under compression. It never felt like the strut to me because the damping performance always seemed fine, but
looking at the car my mechanic could find no other explanation. After having taken the struts out he's found them to be in perfect working order.
He then checked the bearings in the lower A arm and found nothing. He's stumped and I can't do any more than describe it. If anyone has had a
similar experience with an illuminating ending, I'd love to hear it. Thanks very much, Eric Ryder
