I took my Mustang out today for some serious road work on a couple of our great Ozark Mountain roads. The SO was with me for the first time, and she said that on 2 occasions, she could hear what she called a grinding noise from the left rear. Both times, I was driving into a curve pretty hard (70 in a 40 mph posted curve). It did it with the TCS on or off, doesn't matter. My hearing is not the best, so I haven't heard it. I have to go by what she said.

Check my sig for my mods. Note that I don't have any mods to the panhard bar, or the rear shock tower brace. I'm wondering if the noise she is hearing is the rear end shifting a bit when it's under a lot of lateral load. Any ideas?

 

If it was grinding you would think you could feel it.

 

Sure it wasn't loose gravel? Maybe?

 

I guess there are any number of things it could have been. Since I didn't hear it, I'm handicapped in trying to pin it down. My driveshaft clanks a little bit, and I asked her if it was that sound, and she said no.

Does the ABS still work with the TCS turned off? I didn't feel anything in the pedal, but I wonder if the ABS was on the verge of kicking in.

 

There is a service bulletin you might want to check within this site's "Warranty & Service Issues" It is number TSB 06-12-11

 

Has anyone else had this problem, because I only hear like a moan or groan every once in a while and when I take it to the dealer they say they cant replicate the problem and now my warranty is almost up
