Re: '04 Grand Cherokee Lurch on Stop...
 

Hi all,

Just wanted to thank all of you for your help with my "bump stop"
problem. I brought it back to the dealer (it was under a 30-day
warranty), who told me that nothing was wrong, but decided to grease
the rear driveshaft slip yoke splines myself. Fixed the problem.

Thanks much,
Tom
