300 c AWD 11,000 miles. Just had tire rotation done, soon after, started noticing vibration while turning steering at parking lot speed. the vibration is there whether the car is is N or D, reverse or FWD. and it does it intermittently mostly in the mornings, or after the car has had a chance to cool. has anyone heard anything like this? please help!

 

Hello,

I joined just so I could input on this problem. I had the exact same thing in my Magnum RT AWD. There is a TSB out for the Magnum, but I just looked and did not find one for the 300. Dodge calls it "crowhopping" and it is a hard vibration making slow turns, especially at parking speeds, and it is only in the AWD. At first mine did it only in the morning, after driving 10 miles, it did not do it. It got worse and worse until it did it all the time.

My dealer replaced the transfer case and problem is gone. The TSB says the vent tube is misrouted, allowing water in. The new case has the vent tube in a protected place so water can no longer get in. Hope this helps.

Here are the details for the Magnum TSB:
