I have a Dodge Avenger 2009 R/T that I recently changed out the left transmission and front motor mounts over Labor Day weekend. Everything went by the book smoothly without any issues. Front-end noises solved!
For clarity:
- there are two vertically oriented bolts.
(1) One in the "front" that goes through this hockey-puck dampener, through the transaxle frame, into the mount. M10 x 1.5 x 50
(2) One in the "back/rear" that goes through the transaxle frame into the mount. M12 1.75 x 55
- there is one horizontally oriented bolt
(1) goes through the motor/motor mount/motor. M10 1.5 x 90
I had tightened all of the bolts to 45 ft-lbs at first (girlfriend was sick and I had to get some meds so didn't triple check the torque settings...), when heard the same klunking/metal groaning noise coming from front again about 1 week later, but still not as loud as before. Checked the manual, realized I had to tighten the front-most mount-through-transaxle bolt to 75 ft-lbs. Did that, and noise went away.
About a week later, the same noise came back. I called the local dealer to find out the bolt sizes to replace the bolt (in case maybe threads had stripped?) and use anti-seize. Jacked up the car again, raised the engine a smidge, and checked all the bolts to see if any were loose again. The rear vertical and horizontal bolts were fine. The front vertical bolt spins in place but isn't tightening OR loosening (with hand-tool OR impact tool), and there is some play in the dampener (hockey puck thing) which had otherwise been snug and still.
Photos attached!
Any one have this happen before? Suggestions? A friend mentioned a heli-coil..
