That would deprive other members of valuable information. It's best to keep the conversation here.

I'll post an update on wednesday. It is at the dealership where I bought it and that is three hours away. I plan to spend a day on that side of the state putting on some major miles on it before before heading home. Dealer agreed that i would drive it for day and have them check it out again on Tuesday. I hope this finally fixes the problem, unfortunately I am a little doubtful at this time having been told in the past by dealers in my area that the Jeep was fine. keeping my fingers crossed
 
I think it's time for owners to get together and take the issue to Chrysler. I am trying to put together a pattern and see when the problem '07's were built. I know that mine was built in May of '07 and it is a Rocky Mountain with the 4.7.

2008 GC shutter by afran

My 2008 GC has the shutter problem. The problem is that it is not always there!
I finally got my dealer to agree to replace the torque converter after working with Chrysler engineering. Unfortunately I had to leave for the Winter in FL so I'll have to wait until I return in April.
I'm interested in how you do with your repair.

Picked up my Jeep as planned on Monday. Dealer replaced, torque converter, rear driveshaft and u-joints. Also did front end alignment. I have driven the Jeep nearly 600 miles since picking it up and I think the problems have been resloved. Much smoother at highway speeds and the shudder appears to be gone. There still is an issue with it only turning 1,100 - 1,200 RPM's at 35-40 mph but that can not be fixed until software changes are released. So far I am very pleased with the results

Bad, bad, bad...bad vibrations by passthelube

Just traded in my 02 Liberty for a loaded 08 JGC 4x4 Limited with the Hemi. On my way home from the dealership, I noticed a vibration at 70 mph. As it was a short drive, I didn't experience it but for maybe a few seconds. Yesterday I drove it on a smooth highway and the vibration started around 65 mph and seems to persist through 80 mph, and is at its worst around 72 mph. Steering wheel shakes so badly I couldn't imagine driving like that for very long; I think my arms would go numb!
 
Because the dealership had the car transferred from another dealership located about 100 mi away the day I picked it up, I can see no reason why the driver wouldn't have informed them about the vibration. In my opinion they allowed me to drive a defective vehicle off the lot.
 
I'm taking the Jeep back this morning, less than 48 hours after buying it, for service. Based on what I've read here, I'm in for a long, grueling process.
 
Question: is the vibration problem limited to 4x4's? Is it limited to the HEMI?

Hello Bad Bad
I had a similar problem #1 check the wheel tire balance weights the should not be over 1-2 ounces I had on mine 3-4 ounce weights on all tires, Goodyear Fortera HL OWL tires. I took to a goodyear dealer to have all tires balanced on a road force machine, found a wheel (not tire) was bad, I met with a Chryser Rep. and told him to put on the spare. the vibration greatly decreased, I said I was still unhappy. I told him I want all new tires. They put on 4 new Michelin Cross Terrains, there were balanced, and all wheels have 1 or less weights, Your Jeep might need wheel alignment, It all this fails it torque Converter or drive shaft, read all messages in Jeep Grand Cherokee Vibrations
GOOD Luck .....................................

Thanks for the advice.
 
Jeep service department told me they found that one of the front wheels was out of balance, but after adjusting they test drove it and the vibration was still there. They are going to keep it overnight in order to replace the front drive shaft tomorrow morning.
 
We'll see what happens.

Problem fixed, or so it seems by passthelube

I picked up the Jeep tonight and test drove it on the highway. No significant vibration between 65-75.
 
I didn't get a chance to talk to the service technician as he had already left for the night, so I'm not sure exactly what all had to be done. I do know they installed at least one new driveshaft and another part that had to be delivered from Houston (to Austin). I'll find out the details when I call the service department tomorrow and post them here.
 
So far, so good, but I really have to drive it for several hundred miles to ensure the fix is permanent.
 
Will keep you posted.

Passthelube,
 
Curious how you made out Lube. If reports are still good, please let us know what parts were replaced.
 
Thanks,

Vibration fix procedure by jaybee5

Hello gentlemen, you are lucky to put "just" $43000 for a new jeep. Here in Europe, it costs at least 50% more..
 
Anyway, I have same problem on Overland HEMI 5,7 2008 - steady vibrations at around 70mph, dont seem to be affected by accelerating or putting transmission on N. Vibrations disappear at higher speeds.
 
Going through posts, I think following would be procedure to try to fix the problem:
 
1) Have tires checked and balanced on tool with road-force feature. Check that weights go on both sides of the wheel, inside and outside. Check that weights are not much more that 1-2oz - heavier weights may indicate inproperly manufactured tire.
2) Check perimeter of wheels if it is same
3) If vibrations persist, instruct dealer to check tsb_wh_1600105.pdf (for export jeeps), possibly use vibrations monitor?
4) Dont have service flash software - this causes problems and does not help
5) Finally, replacing torque converter, rear driveshaft and u-joints and doing front end alignment could fix the problem.
 
Any suggestions to the procedure? So we could then tech Chrysler how to work?
 
Jan
