A couple of years ago I had a creaking sound/feel in the steering wheel. The dealer wasn't sure how to fix it and had to wait about 3 weeks for Chrysler to provide a fix. I am not really sure how they fixed it.
On the paperwork the dealer wrote
"Removed Lower Dash Panel - Removed kick panel - loosen up center steering support - realigned and tightened - road tested warm and cold"
This is from the Service Manual under Steering Diagnosis
SQUEAK OR RUBBING SOUND
Possible Causes.........................Correction
1. Steering column shaft rubbing. 1. Move or realign item rubbing shaft.
2. Clockspring noisy.................. 2. Remove clockspring. Reinstall wheel.
.................................................If noise is gone, replace clockspring.
3. Steering gear internally noisy... 3. Replace steering gear
There is this TSB, but I don't think it applies.
