My 2007 MKZ has 55,000 miles. Lately have noticed sounds from the rear undercarriage when going over uneven bumps and uneven pavement at slow speeds. Sort of like metal flexing. If it had shocks I would think one or both had failed. I don't hear the sound when I push down on the rear bumper. Struts should not fail yet should they?

2007 Mercury Mariner 4WD 175,000 miles. Undercarriage rattle at slow speed on washboard road. No issues over large bumps or speed bumps. Have had inspected with no luck.

The most likely culprit would be the exhaust moving and tapping the bodywork or something nearby.

Could be springs or shocks?

Check engine rubber mountings.

If your spare wheel is in a wheel well in the trunk, check for something in there loose and shaking about.

2006 Buick Rendezvous rear end feels like it is fishtailing when driving on uneven pavement

On a 2006, the towing weight probably split the Sway Bar bushings. The sway bar stops the back from swaying. Could also be shocks as well or both.

Push down on the back and see if it bounces.

Go under the vehicle and check for broken exhaust pipe clamps or the pipe or muffler hitting on the undercarriage, check with the system heated up as it will expand up to 1 inch. Also you may need suspension bushings, they are pretty much done at about 100,000 mile mark.

The lincoln had problems with the engine mounts, the first thing i would do is to have all the engine and trany mounts checked and also the front suspension, i dont think its the running of the motor because the check engine light is not on, so it would have to be a mount type problem good luck, hope this is helpful.

check front end components, you may have a bad bushing in steering, or a bad part in front end. JUST GET UNDER AND CHECK IT OUT!!

MKX ''Clunking'' during slow acceleration

Could be a bad CV joint. Check to see if any of the CV boots are torn. When they are torn the CV joint slings all the grease out and causes the CV joint to get dry then they start to make noise.

Probably best for a second opinion. Did you purchase an extended warranty?
