Ok guys I'm stumped. My '98 c43 is making a bad knocking sound at slow speeds in turns. Thought it was the wheel bearings, repacked and still knocking. Than local shop said transmission mount and so we replaced that, still knocking. My next move is the motor mounts, but wanted to bounce it off the forum. Car has 80,000 and all the front end parts have been replaced. Any ideas?

Thanks.
