I have a 2003 Yukon XL 1500 4WD with approximately 120k miles. I have recently noticesd that the front suspension feels loose or "jiggly" when going over bumps almost like I was riding on Jello. I just had the truck inspected and asked that the dealer look for any problems. They indicated that all was OK. Since then, I replaced the front shocks, even though the originals semed OK, with no change...still loose. I asked the dealer specifically if the internmediate shaft was lubed and they indicated that it was OK although I only get a clunking noise going over larger "sharp" bumps. I called the dealer and they suggested bringing it in to see if they can find anything but I can not afford to have them randomly trouble shoot at my expense. Can anyone suggest where I should look for the problem?? Any suggestions would be greatly appreciated.
Thanks
