Re: 2008 Uplander Two Issues - Vibration and Noise - Front End
Other things got in the way and I just got to check these items today.
All six bolts on the braces were all a little loose, front and back. I tightened them and there seems to be no more clunking, at least not on the driveway. I have not yet taken it further.
The bushings at the front of the control arms look good with quite good clearance between each control arm and frame parts. However, I did notice that the seal above the ball joint on the driver's side looked quite empty. I pressed on it with my finger but could not tell that there was any grease left! I saw no rust coming from it, but it's possible that this sealed joint has prematurely gone dry and is rusting inside! Could that cause the vibration when braking? I've replaced ball joints on other vehicles before but those vehicles did not vibrate like this one! The ball joint on the passenger side looked much better with the boot seal much fuller.
