I was trying to get rid of a clunking noise coming from the front suspension on my 1997 E320 going over rough roads. I took off the bearing caps and was checking to see if there was any movement. When I hold the wheel at 12 and 6, there seems to be some noise emitting. I thought that I would try and tighten the wheel bearings. I loosened the allen cinch bolt and turned the nut finger tight. I then tightened the cinch bolt. Did I over tighten? I know I should have a dial indicator to check and verify this. I took it for a drive around the block and the noise is still there. I don't want to drive it anymore until I know if it is too tight.

Also, how would you test to know if the sway bar links would be making the noise?

TIA,
Steve
