Sajeev–

Here’s a weird one to test your skills of remote diagnosis. Fire up your Magic 8 Ball for this one.

Car: 2012 Mustang V6, manual gearbox, performance package (currently running some crappy General AS Max-03 tires), 33,000 miles. I’m the only owner; special ordered to get it just the way I want. Mods limited to a Shaftmasters one piece drive shaft ( scared into it by a few YouTube videos), a Draw-Tite receiver hitch to pull my one bike motorcycle trailer, and an 87 octane tune uploaded via SCT (on your recommendation). The car will go into a nearby Ford dealer for a look at this issue under warranty this coming Friday, but based on the “quality” of some of the work I’ve had done over the years, I thought it would help to give the techs some clues.

Problem: For the past few days, I’ve heard irregular “bangs” or “clunks” from under the car.
