I'll keep you posted.
How much did it cost for the new torque converter or the new drivelines?
Thanks,
still waiting for Chryrser Engineers to set an appointment to look at the VIBRATING JEEP sticker was 41,500.00 and it rides like [non-permissible content removed] . this will be my one and only JEEP if this problem can't be fixed
the major Problem is the wheels with the PLASTIC wheel covers.
Chryser/ JEEP should admit the problem are with the wheels. Stop putting those wheels on the SUV'S. they should try Michelins or yokomahamas. or just recall all the JEEPS and fix them..........................................
Unfortunately the dealer wanted to change the converter just as I was leaving for Florida for the Winter. He told me to go to a local dealer and he would replace it.
After getting the run around for the FL dealer I've decided to live with the problem until I get home in the Spring. Then I'm going to trade in this POS for a real car like a Lexus or a BMW. This car has 7K miles on it and had the vibration problem since I got it 3 mos ago.
Never again will I buy Chrysler(this is my forth!) and I'll make sure that everyone I know hears the story, especially the folks on this forum.
I guess we know why the Japanese are taking us to the cleaners!
There was a TBS for a ECM Flash to improve Torque converter operations. Does anyone know what this actually does:
Bulletin Number: 2101105
NAG1 (W5A580) TRANSMISSION - SHUDDER WHEN TORQUE CONVERTER CLUTCH ENGAGES. *TT
Bulletin Number: 06002
FLASH TCM AND ECM TO IMPROVE TORQUE CONVERTER OPERATION. *TT
I don't think I'll keep mine that long...Its gone in the Spring!
I'm am trying to put together a case that Jeep knows of the problem and has no fix for it, so the Jeep delaership (who performed the repairs) really did not have to replace the TC.
My point is that Jeep knows the problem, it's a fairly common problem and I honestly want my money back because the problem is still there. I want to go to the owner of the dealership provide him of the evidence that this is a common problem with no known fix and ask for my money back.
Can anyone point to a resource or someone to talk to get more cases of where Jeep has acknowledged the problem and has said in public that they have no fix for it?
Several people on the board mentioned some engineers they have spoken with, is there anything out there in the public about Jeep talking about this issue?
I did find this link that might be of interest with a few suggestions of a fix. You need to read further down:

Any help would be appreciated.
Thanks
I had a meeting with the service manager at Dover Dodge and the regional manager with Chrysler on Wed 1/16/2008. We all when for a highway ride 60-78 MPH.
I told the rep about the problem with the Goodyear fortera HL OWL tire balance problem. 1 Wheel was found to be out of balance they removed that right rear tire and put the spare tire on the Jeep, the vibration did decrease, however I said I was still not 100% happy. The Chrysler rep asked what I would like. I said I want all new tires on the car since those Fortera's seem to be the problem since all the wheels had 2-3 oz of weights on each one. I wanted Michelin Cross Terrain SUV tires.
Friday 1/18/2008 I took the Jeep back to the dealer, they installed the 4 new
Michelin tires, I took it for a 25 mile highway ride. Results are NO VIBRATION at all. much quieter and smother ride. Less than 1 oz weight on all the wheels
My advise to all jeep owners with Fortera tires, tell the dealer they want all new tires and not Goodyear, they must be having a Badyear making good tires.
This thread applies to a driveline vibration on '07 and '08 Grand Cherokee's that ONLY occurs at speeds between 65-80 MPH and has to do with the drivetrain. More specifically, the driveshafts. Most have the Hemi engine. It is NOT about other year vehicles or crankcase problems. Please start a different thread for earlier year vehicles as we are getting a bit off the path of the original posts.
Thanks to all,
Alan

I need your assistance with vibration problems on my '07. If anyone has had their driveshafts or u-joints replaced by the dealer could you let me know. So far the dealership I am working with will not replace mine and says that the vibration I feel is a characteristic of the quadra-trac II system. I am waiting to have an area rep review my complaint but would like some back-up material to show them. Your assistance is greatly appreciated
The way I'm going to fix mine is to get rid of my 2008 GC ASAP and buy a car from someone who knows how to design them...BMW, AUDI, Lexus...too bad they are not American brands!
The main culprit seems to be the torque converter and not the joints. If you search the thread further you can find some other ideas and get more information on what HAS NOT worked.
We are so ticked off with jeep that we want to get rid of it, but there no longer is value in jeeps. So if any else is interested we want a class action (although - I am not sure that is what we have?) but yes were disgusted with the poor product we bought.
Jeep should know that their product sucks!
I have once agian sent a letter to Chrysler Customer Service, also included one to all the top people at Chrysler. Don't know that anyone will read it or even care but its a start. As I feel everyone else's frustration I now know that I am not the only one out there with the same problem. They still have not gotten back to me about a potential software fix for the premature torque converter lock-up at 35-40mph, because of this I have gotten into the habit of using the tow/haul mode. I should have kept my Durango that had 102,000 miles on it.
How did the car feel after the fixes? I have an '07 fully loaded GC Hemi with the same problem. They changed my front and rear driveshaft for about a 75% improvement. I have not had my torque converter addressed. Describe your problem a bit more to me and at what speeds it occurrs. Let me know how you make out. You can e-mail me at alankm@snet.net
Thanks,

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

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.
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.

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 .....................................

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?
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.
Loaner car: PT Cruiser.
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.
Curious how you made out Lube. If reports are still good, please let us know what parts were replaced.
Thanks,
Alan
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?

My car is currently at repair service with vibrations 40Hz (2400 rpm) at 75mph. If that is not successful, I am gonna ask them what are allowed quality tolerances for balanced shaft and I will then take car for shaft measurement and balancing to independent company.

How do I know this? READ! I have the same car and the same problem and it has been an issue on my car since day one. I ruled out my tires and weights and isolated the problem to drivetrain. How? It only happens at certain speeds. They replaced the rear driveshaft and that helped a lot but the problem was still there. Then I brought the car back and said it's close but no cigar. Then they called "Star" again and they recommended replacing the front driveshaft as well. That got me to 90% which is the best you will ever get so I am living with it as it is only noticiable because I have been aware of a problem in drivetrain shudder between 70 and 75MPH since I bought the car. Now, I have constant check engine lights coming on that I am dealing with. I love the car but the quality control scares me.
Alan
(1) It's a 21Hz "vibration" at 72mph that i've found (40Hz is out of the driveline range)
(2) It's been a process of elimination with this vehicle - transfer case shield (yes, they vibrate), MDS, other body harmonics, exhaust, etc.
(3) Yes, when the MDS turns on, you can feel (and sometimes hear) it. You can feel the surging if you really pay attention. Turning off 4 cylinders WILL cause a change in engine harmonics - there's just no way around that.
(4) Under warranty guidelines, we can't install export driveshafts under an older model TSB that doesn't apply to the vehicle being worked on (Chrysler would just reject the claim and all h*ll breaks loose at the dealership for us)
(5) Star is sometimes of no use to us unless you get a well seasoned "veteran" on the phone
(6) We can't just throw parts at a vehicle in an attempt to fix it.
(7) It's bothering me as well that I can't get a clear answer on what it is and have to take all of these steps to figure it out. However, this forum gave me some better direction with the export TSB post.
With that said....the rear driveshaft part number on the export (2005) WK models is the same up to 2008 models. There is only one revision on it since the TSB came out. So...i've ordered the rear shaft to find out what the difference is and to find out if this actually fixes it or not. Will this fix the issue on all Jeeps in question - there's just too many variables to say yes or no - weight, load, road conditions, tire size/make/model, driveline configuration...they all come into play one can't say for sure that "all" have the same vibration unless you know that all the ones making this vibration are physically the same.
I respsect the fact that you are a technician and I am not. However, It was pretty easy to isolate the problem to the drivetrain for me. In fact, when all was said and done I found out that Star was recommending driveshaft swapouts for the problem. That was interesting because I felt the problem was in this area the entire time. After the rear driveshaft was replaced, there was about a 50% improvement. I took the vehicle back and said close but no cigar. I suggested they change the front driveshaft as well being that there are two driveshafts on the vehicle. Turns out I had to wait over a month to get a front drivesaft because they were on national back order! Coincidental? I doubt it. When my front driveshaft finally came in and got replaced, the improvment went up by about 40% giving me a grand total of 90% improvement.
The saddest part to this blog is that people have to research and surf the internet for answers and help because Chrysler won't acknowledge the problem even though they are aware of it and feel that leaving the lot after paying 43K for a new truck with a shuddering vibration should be acceptable.
