The clunking occurs over bumps only, even small ones. It seems more pronounced the bigger the bump. At speed on the highway it doesn't make any noise. > a-arm with spacers and disconnect the sway bar to see if the ball joints > have slop.

This particular mechanic replaced the clutch last year and did a good job with that, altho from what I hear on this ng, clutch replacement on the OG 900 does not require a rocket scientist. He put the car up on the lift, but I didn't see exactly what he did. He said the ball joints and front end is solid and do not need any work. Then we took it for a little test spin and couldn't get it to clunk. Then of course when I got back in and drove away I started hearing the clunk over bumps again. > could it be: > I am very familiar with this front brake pop we starting off in reverse and have grown used to it. The clunk I'm talking about is different. > Wheel bearing is possible I guess, but it doesn't necessarily happen on corners. If it's a smooth road surface, the clunking doesn't occur when cornering, even at high speed. The CV joints don't make any noise when cornering either. > if it is a NG900, it may be: > Nope, it's an OG. > Just trying to be of help, I appreciate it. I wish I had the time, tools and work area to check them myself. Living in the city w/out garage or driveway and long work hours make this impossible, unfortunately. I'm planning to drive from Providence, Rhode Island to Westchester Cty., New York this weekend for business (about 400 mi. roundtrip) and hoping it makes it. -jw
