I have previously asked the dealer specifically about the power steering tsb and they said mine wasn't a condidate with a production date of 3/11. I didn't challenge that as I don't feel any vibration in the steering,...it's a sound (similar to all of a sudden at 2krpm somebody slipped a set of howling rough treads on your rig and simultaneously you feel a vibration in the seat and floorboard. That's the way it is on my rig. It goes from 68mph on up. They are rebalancing the rear shaft as we speak and I should have it back tomorrow. If that doesn't work then my inclination is the transfercase as when they took out the front shaft prior to rebalancing it,...there was no drone or vibration. Also as a mental tickler,...I ran my truck at 2krpm in the tow mode and no drone or vibration?? Would that indicate something in the transmission, i.e., Torq converter?? I suppose if they start at one end of the truck and replace everything going back, then maybe they'll get it. Go figure.

 

Let us know what you find.........

 

Highway Vibration Fixed
It has taken six months, ten service trips and countless hours on the phone with Dodge , American Axle and different dealers but heres what has taken the vibration away at expressway speeds.
Its the very first thing I told them when I took it in for the first time. The transfer case. I have had four rear driveshafts in, one front shaft and a new rear ring, pinion, bearings and now the transfer case. This has taken the vibration out about 95%. There still is a slight vibration when you are under throttle till you reach your maitained highway speed then it subsides. This I believe is still the rear driveshaft but when they come out with a larger dampner on the shaft I think it will be gone also. If you can move the dampner on the driveshaft (where it slips on to the transfer case tailshaft ) up about a 1/8 to a 1/4 inch by hitting it with your palm of your hand its too sloppy. This is the second truck this engineer has replaced the transfer case on and on both trucks it has solved the vibration. It took a lot of complaining at the dealer level before the Dodge engineer got invloved. But now Im almost vibration free and this truck is great.
