Yeah sorry, I should have worded it a little better, I was in a hurry. Knocking is a much better description of the noise, it almost sounds like someone shaking a marble in an empty can of coke. I did mean RPM of wheel, sorry again. I jacked it up and put it in 1st gear tonight and turned the wheel; the knock would come intermittently at a random interval (definately passenger side, most likely inner). All the boots are fine and both axles have extremely fluid movement when moved by hand. After I performed this inspection, I drove the car about 20 miles and its not knocking anymore at all. Is it possible I massaged some grease into an unlubricated part of the joint? Right now, I'm just going to drive it around town and see how she does. Maybe it was just the cold weather. My brother suggested it might be spider gears in the differntial, but I'm not sure he knows vangons too well.

Thanks again,

SPC
