So after all day fighting with the tire place and mickey thompson they are sending me a new set, going with a 35/12.5/20 hopefully these dont make the truck shake, guess we will find out late next week.

 

Definately your tires then! Just sounds like they are all out of balance! My 20's went on a road force balance machine. They are 33". No problems at all.
Did you get the sticky weights? I got mine for the front, but the backs were normal to the lip. Sticky weights can effect balance as much as anything else!

Check this link out! It's worth a shot. http://www.off-road.com/trucks4x4/ar....jsp?id=277569

 

I just had this problem on my 3500 with 35's the problem ended up not beiing the tires as everyone suggested to me. The problem was because of the spacers i put up front so I got front end alignment and that corrected the problem.

BTW my problem was death wobble. When going down the road when I hit a bump at 55 or above the truck would shake really really bad.

 

Good deal bro... hope that works.

i'm still running oem hp's - i started off 3 weeks ago with just a shudder in 4x4 hi, then it went to a vibration in 2wd at highway speed... now i have a shudder in 2wd at all speeds... i'm on the verge of a complete ballistic meltdown with this POS truck!!!!!!!!!

 

Yeah To Bad they dont make a steering staiblizer for our trucks.

 

oh yeah these truck soooo need a steering stabilizer

 

Whats the deal with your trans motor issue, ever ratchet it down.

 

i got under the truck... there is a mount, but it's a crappy set up IMO... it allows the entire tranny to move side to side at least 2" and up and down a good inch.

I wound up taking it to the dealer again for today, so i didn't ratchet it down now.

at this point, i'm discussing things with my attorney and I plan to start the lemon law paperwork here in NY.

I'm tired of this crap... the dealer had it all day and basically did nothing but say it's within Chrysler specs... and the 2wd shudder is getting worse... not to mention the 4wd shudder.

 

There is absolutely no way that a powertrain that can move that much is within spec. Something is loose or broken. 100% Certified Bullshiat. If a dealer tech told me that was normal, things would get ugly fast. I think lemon law is a good play.

 

Wheres parts and service ?
