Replying to: fasstdak (Mar 21, 2008 7:13 am) I bought an 05 JGC loaded with a hemi and noticed a vibration at highway speed 75mph (but is present from 60-80+). To some it up I have exclusively serviced my jeep with Jeep and have done everything to assist the dealership in eliminating the easy causes. My Jeep currently has new tires, two new rims, and new brakes/rotors. The tires have been balanced many times and the truck has been outfitted with test tires to rule out a tire/rim balance issue. the dealership replaced my rear driveshaft, but it still vibrated when I picked it up. Jeep then got an engineer involved who put vibration sensors on the car. Determined that the vibration was coming from the rear. They spun the rear prop shaft several time s but vibration persisted after four moves. They then replaced the rear ring and pinion gears, both pinion bearings, set preload and backlash and replaced the rear axle pinion flange yolk. Vibration remained as documented by tech after all work was complete. The regional rep did not allow anymore test and told service manager that the engineer said it (the vibration) was within acceptable tolerances for a 4 wheel drive vehicle at 75mph. This is currently an open case under warranty and my Jeep has 33,000 mi. This is Jeeps flagship Grand Cherokee and should not shake my hand on the wheel at 75mph with passenger seat visibly shaking when unoccupied. I love my truck but this shaking is unacceptable, had a 2000 JGC that didn't shake at all at these same speeds. Any advice??? Called the Jeep and still have an open case. Waiting for a call from the dealership to coordinate another evaluation to further investigate. I could use any help you could provide me. Thank you

Replying to: 05hemi (Sep 05, 2008 9:30 am) I see these vehicles (different configurations) on a daily basis at the dealership and while I agree there is a slight vibration, it seems to vary in severity from vehicle to vehicle. Is this a "normal" vibration...hard to say. I've done quite a few things in order to eliminate the vibration and nothing works the same in each case. Blaming it on one item for all models is silly as i've changed driveshafts on one GC and then a tire rotation on another...both calmed the vibration but both required different apporaches. Personally, the Jeeps have vibrated in one way or another since the late 80's - driveline whine, "floating" on the highway (solid axle design), and now vibrations at certain speeds. These are NOT luxury SUV's...they're still Jeeps and are not a super refined vehicle. While the creature comforts are optional (power this/that, etc.), they're still a JEEP. The only other thing which comes to mind is tire selection. While the OEM tires on these vehicles are good, there are much better options which also ride smoother and help absorb more of the road and suspension harmonics in the process (GM was notorious for this back in the early 90's on their trucks). Wish I could help more...but unless someone wants to redesign the Jeep chassis, it doesn't look like there's going to be a solid fix any time soon.

| Are you talking about "Road Force" balancing? That's a very common practice and we do those here quite often. | |

Replying to: jdejeephemi (Oct 16, 2008 11:38 am) Your Mich tires should not have more than 1/2 ounce of wheel weights if they do the wheels them self are the problem the plastic cladding is part of the problem I had the same problem 1 year ago, now 8000 miles of my 2007 Jeep GC limited hemi all new Mich tires were installed 1 bad wheel was found 1/2 oz weight is all 4 wheels NO Vibration since Good LUCK

Replying to: 05hemi (Sep 05, 2008 9:30 am) I here a lot of talk about rims and tires, which has been ruled out with my vehicle, as they trouble shoot my truck using shop balanced tires and rims to rule out any tire/rim related vibration. I drive from upstate NY to Philly frequently and have extended drives along flat and hilly terrain, but the my Jeep Limited Vibrator continuously shakes. My passenger seat visibly shaking the entire time. My Jeep seems not to be shifting as gracefully when traveling through the mountains in PA. At 43,000 miles this truck seems to be falling apart, my 2000 with 165,000 had less problems. I am sure other jeep owners are in the same boat with an inability to unload this vehicle, because their resale price is rapidly decreasing. If they could fix this vibration that would make it sooooo much better. I wish I could post a video of my passenger seat vibrating while I drive on the highway. Check back in a week or two, I will post a video on youtube. Sorry for the rant, but my purpose is to gain any information that people have had luck with solving this problem! I don't expect perfection, but this is unacceptable |
