Thank You...! I agree...!

 

I definatly know the difference between the TC & MDS issues.
Personally, i think you`ve done some mods to your truck and that may be the whole reason why your`re having problems.

 

Can you provide a link to this TSB? Thanks

 

As of yet there is no TSB.
There is a Star Case... https://dodgeforum.com/forum/attachm...1-37-20-am.jpg

Basically special instructions to dealers on how to treat a certain complaint.

I printed the photo, took in my truck and asked them to test for this, they have ordered the new torque converter, should be in soon.

 

SERVICE BULLETIN

NUMBER: 22-001-10
GROUP: Wheels/Tires
DATE: April 08, 2010

THIS BULLETIN SUPERSEDES SERVICE BULLETIN 22-001-09, DATED MARCH 7, 2009, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE THE ADDITION OF VEHICLE MODEL YEARS.

SUBJECT:
Vehicle Vibration or Shake at Highway Speed

OVERVIEW:
This bulletin provides information to diagnose vehicle vibration concerns at or during PDI or if the vehicle is stored for a length of time prior to delivery.

MODELS:
2009 - **2010** (DS) Ram Truck (1500)

DISCUSSION:
Tires used on the 1500 Ram models can develop a temporary flat spot when sitting on the lots and or while being shipped. This condition is more prevalent on 4 x 4 models with 20" tires and wheels due to the additional weight on the front tires from the unique components (i.e., front axle and transfer case). Weather is a critical factor and temperatures significantly above and below normal temperatures can temporarily "flat spot" tires when vehicles are shipped by car hauler or rail or if vehicles are stored for an extended period. The vibration may be felt in the steering wheel and / or seat, and may be most noticeablr at highway speeds, 60 MPH (96 kph). This may be misinterpreted as an out of balance tire.

DIAGNOIS:
If the tires are flat-spotted due to shipping or sitting in the lot for an extended period, the vehicle vibration will go away after the tires are warmed up, (normally 10 to 20 miles of highway driving depending on outside temperatures).

REPAIR PROCEDURE:
1. Road test vehicle 10 to 20 miles to allow the tires to obtain operating temperature.
2. If highway driving doesn't resolve the vehicle vibration, follow the procedures outlined on DearCONNECT>TechCONNECT>Group 22 - Tires and Wheels.

NOTE: Replacing tires should only be done as a last resort after all appropriate wheel and tire diagnostics have been completed. U.S. dealers can contact the MOPAR tire program at 1-866-877-TIRE (8473) if assistance is needed with obtaining a tire. Canadian dealers can contact the MOPAR tire program at 1-866-529-8473 if assistance is needed with obtaining any tire.

******end of bulletin***

Needless to say this did not really address my problem since when this issue arose I already had better than 15,000 miles on the vehicle. However, after talking to a number of owners and service people I've come to suspect the clue is in step 2 of the repair procedure. If this truly could never be anything other than a "temporary" condition resolved by warming up the tires, there wouldn't be a need to replace a tire. There's a fair amount of opinion that the problem is the Wrangler 20 inch tires are prone to flat spot, and that's followed-up by evidence from owners who have switched to another tire make and had the problem completely disappear.

Dusty

 

I replaced the tires on my 2011 Sport 5.7L 4x4 and still have the shake at highway speeds. Also have the partial throttle rattle. It's not the tires.

What tires are you running now(?)
New tires aren`t properly balanced...? Possible bad shock...?
Were the wheels checked for out of roundness when new tires were put on...?

Dusty
Big thanks for adding the TSB, this will hopefully help others.
My truck had this very issue, tires fixed that problem per TSB bulletin.

 

LU229 I'm running Hankook DynaPro ATMR10's (stock size) on Monster XD Addict 20x9 wheels. Had a bad shake at 70+ mph and had the tires rebalanced. No joy. 2 additional balances later and Discount replaced the tires. I still have a shake but not as bad. That said, I still also have the partial throttle rattle. As I said, it's not the tires.

This is my 3rd Dodge P/U and 4th Chrysler vehicle and I've gotta say, they didn't do a very good job on the 4th gen. Atleast not on my 2011.

 

These 4th gen trucks are VERY fussy with tires. What i`m seeing, is these kinds and types of winter type treaded tires shake due to this kind of tire. I just put 4 brand new winter tires (stock size, stock steel wheels for winter tires) and i too, also have a shake with the new tires.(i too, installed a similar kind of tire that you did) I put my original OEM summer stock tires back on the truck, no shake.(smooth an no shake all the way up to 100mph) In your case, i feel that it IS the tires causing the shake. I`m no tire expert here, but these winter type and all terrain kinds of tires dont have as good of side wall support that the summer time sport treaded tires do in my opinion.(they concentrate more on the more agressive deeper tread patterns but they still have the same type of sidewall design as a summer tire does) My friend has the same truck, he put winter tires on, his now shakes too. In my own opinion again, i dont think the OEM shocks are handling the job very well either. I also agree with you about the 4th gen trucks and how they have not done a very good job with them. They`ve made them pretty trucks, but not very effective trucks otherwise, meening driveline issues. The suspensions in these trucks have now become way to sensitive, then when you install tires that have alot more agressive meat around the tread areas, (like an agressive deep treaded snow tire) it tends to throw them out of balance because of the outter area of the tire is alot heavier. So i think what happens is, the tire grows larger in diameter due to heavier tread. Think of it as a centrifical force that grows larger as the tire turns faster and faster speeds. I dont know what else it can be, just some thoughts on what i think may be the issues when switching from light summer tires vs heavier snow type tires. We are always going to give up something to get something else. Whats the pay off in the end, its anyones guess... especially with tires.

As for your throttle rattle, what do you think it is....
The torque convertor issue, or the MDS vibe/rattle issue...???

Couple of us are working on developing a "bolt on ballast" for the MDS rattle,(to absorb the vibes created by being in MDS mode) we`re still in the testing phase right now. We`re close with defeating the MDS rattle with a ballast, and continuing to improve on the ballast design. If we get this ballast to work, we will be letting people know about it. I suspect by summertime, we`ll have it working very well.

 

Unlike others I don't seem to really have any issues with MDS so I believe that the issue lies in the TC. By no means am I a mechanic nor do I attempt to fully understand the inner workings of the TC but rom what I've read and experienced I fully believe that's where the issue lies. I have a case open with Dodge to address this amongst numerous other issues I've had with the driveline (2 shift motors in less than 10k miles) but find it extremely difficult to get a field engineer to take a ride with me.

Just gotta keep up the good fight.
