There is a clunk in the rear suspension, passenger side. Air suspension is good. Bushings look good with no apparent play. 55k miles, never wrecked. CV boots are fine too. Mufflers and exhaust pipes are not hitting anything either. Small road bumps cause the clunking. Jacking up the car and letting the wheel hang does not cause a clunk. Any notion on what is the cause is appreciated.

I am almost 100% positive that it is your rear upper shock mount! These had a problem, and were actually breaking in many cars. I had the same problem on my 1993 Mark VIII and I went with the shock/strut conversion kit. I purchased new shocks when I purchaseed the kit and the new shocks came with heavy duty upper shock mounts. My problem was resolved! You may be able to get away with just replacing the rear shocks and mounts! Good luck. Fellow MARK VIII owner!. Scott Fuller

Dear Mrheene, I'm glad I could help. Eventually, your air ride system will start to fail. If you decide not to go with the air ride system, then I would recommend a conversion kit. They are only around $500.00 and are relative easy to install. I was able to install the kit in about 4 hours and I was taking my time. I am very pleased with the performance of the kit and the ease of installation. I priced the air ride system and it got up to around $1500.00 just for all the parts. Again, glad I could help.

Another thing is that the mk8 has a tendency to break the rear stabelizer bar. check it real close at the connection points, they crack right at the bolts.

Scott Fuller, you got it right on the money!! Many thanks. It was the right rear shock mount, which was causing clunking/rattle through the trunk as the mounting bracket for the air height sensor that sits atop the shock in the trunk was slamming into the trunk floor. I ordered the upper shock mount from Strutmasters for $20. The shock is just fine. Thanks again!!!.

I see three different sets of bushings that can wear out on the rear of this vehicle http://www.parts.com/oemcatalog/index.cfm?action=getJointLocator&siteid=2&chapter=&Sectionids=24,2788&groupid=20127&subgroupid=60181&componentid=0&makeid=21&model=Mark%20VIII&year=1994&graphicID=FFP090&callout=11&catalogid=1&displayCatalogid=0 also look at the link in the diagram it might need replacing.
ANSWER by chipsA , September 26, 2014
That is quite possibly the upper rear shock mounts, and the "smooth" ride adjust solenoid may have jumped off the top of the shock. Pull up trunk carpet at right front of trunk carpet, you'll find a solenoid is rattling around and a destroyed upper shock mount. Now that I C the responses you got, several suggested this fix, and they were right. I apologize for the redundency.
