96 Chrysler Concorde Clunking noise when put in reverse. on 1996 Chrysler Concorde

I have a 96 chrysler concorde with the 3.3L V6 engine. With my foot on the brake when I shift into reverse it makes a clunking noise. When I go from reverse to drive it makes a clunking noise and I can't figure out what it is??? I have replaced the motor mounts, trans mount, inner and outter tie rod ends, CV axles, struts, all 4 sub frame bushings, steering rack, end links and sway bar bushings. Any help would be appreciated the car runs great other then that and only has 75,000 miles on it.

TRY IT WITH PARK BRAKE ON ONLY!! DOES IT DO IT THEN? ALSO WHAT IS IDLE RPM IN PARK?
COMMENT by on October 31, 2012
Yes it does it with the parking brake on and the idle in park is roughly 900-950 RPM

Like I stated above already replaced both motor mounts and the trans mount less then 1,000 miles ago.

HAVE IT CHECKED BY A SHOP WITH A DRIVE ON LIFT!!

I guess I will have to to that. I was hoping someone had a suggestion that I could look into before doing that.

THAT'S THE ONLY THING I CAN THINK OF AFTER YOU HAVE JUST ABOUT COVERED EVERYTHING ELSE. POSS. INTERNAL TRANS. NOISE. BUT WITH A TECH. STANDING UNDER THE CAR AND ANOTHER SHIFTING GEARS I THINK IT HAS TO SHOW UP.

you need to have a competent mechanic in a shop look at it while it is on a lift...when someone is in the car seat shifting it...the mechanic can then pinpoint the clunking noise.

Seriously J Romer, WHO is looking and working on this car? I think you have to find someone else to look at this car after both motor mounts; subframe bushings; cv axleshafts; tie-rods; rack & pinion; and struts were replaced and you STILL have a clunking problem. I think the mechanic is YOU cause there is NO ONE that patient who will allow such "blind sand-bag" repair to be done using SIX (yes SIX) different parts and these are NOT cheap parts either! GET SOMEONE ELSE to look at this car before you buy another part.....(I'm betting that those "tight" motor mount bolts are threaded in wrong and making you think that they are already tight when they really are CROSS-THREADED) ...damn EIGHT parts, I missed the sway-bar bushings and end-links!!!

We are having the same problem and have pinpointed it to something in the differential. The right cv axle has tomuch play going into the differential. We are about to pull the differential and check it out.

Let me know what it ends up being. I sold my car years ago but I'm still curious as to what the cause is.
