Love my truck but hate the vibration- I have all new tires, carefully balanced, and all new 4-wheel u-joints, new constant velocity joint, and just had the Dodge dealer do all new drive shaft u-joints,but still have my vibration.
Had new converted and flex plate installed and had the trans removed and looked at.
However, at 58 mph to about 68 mph I have a terrible vibration, especially under load or on a hill. I do not have it below 58 and over 68 mph. Now, when I touch the Tow Haul Button, The Vibration goes away, when I disengage it, it comes right back! ANY SUGGESTION ????? Thanks in advance HEMI JOE
