Chrysler has a TSB on this:
LH-Vehicles
1. Run the door glass all the way up then very slightly down.
2. Apply masking or duct tape the door glass and door frame to hold the glass
in position while the window regulator is removed.
3. Use the procedures outlined in the appropriate service manual to remove
the door trim panel and water shield.
4. Use the procedures outlined in the appropriate service manual to
remove the window regulator.
5. Remove the grease from the regulator slider run channels with mineral
spirits (or equivalent) using a paper towel or rag. Two passes with mineral
spirits and a drying pass should be sufficient.
NOTE: CARE MUST BE TAKEN NOT TO GET MINERAL SPIRITS INTO
THE SLIDER’S BALL JOINT PIVOT SOCKET
6. Apply BSR Kit Lubricant, p/n 05019061AA, to the channels in the areas
where sliders operate. Make sure to apply grease on all inner “C” channels
as well as the slider’s ball joint pivot socket.
NOTE: PRIOR TO TIGHTENING THE WINDOW REGULATOR FASTENERS,
ADJUST THE GLASS CORRECTLY BY:
• WITH THE GLASS NEAR THE FULL UP POSITION, SQUARE THE GLASS IN THE
OPENING BY PULLING REARWARD AGAINST THE “B” PILLAR GLASS RUN
• ADJUST THE TENSION BY PUSHING DOWN ON THE EQUALIZER CHANNEL
WITH ENOUGH FORCE (2 LBS. MAX) TO TAKE OUT ANY LOOSENESS IN THE
SYSTEM AND TIGHTEN THE FASTENER. DO NOT OVER ADJUST.
7. Use the procedures outlined in the appropriate service manual to
install the window regulator.
8. Operate the glass up and down several time to verify the shudder/chatter/creak
sound has been eliminated.
9. Use the procedures outlined in the appropriate service manual to install
the door trim panel and water shield.
10. Verify the function of the remote handle, door lock, courtesy lamp, window
switches, power mirror, and speakers.
11. Repeat procedure on other window regulator as necessary.
