Clutch Issue?

[COramprat]

2007 GT500...When disengaging clutch there is a rapid rubbing noise that almost sounds like tire rub. It generally occurs when clutching while slowly moving such as slowly backing down the drivway or slowly moving forward when you are kind of slipping the clutch. It's hard to duplicate everytime but it seems to be getting louder when it does happen.

Very hard to diagnose without a video clip.

If the clutch is working fine, I wouldn't worry about the noise ....Fords are noisy

Well...it's in the shop for a new rear end. I met my dad at the shop and took the tech for a ride. He noticed the roar from the rear end during his ride and said the lash was off. I was able to duplicate the noise that we took it in for initially and he said it would be hard to track it down if it doesn't do it regularly. Maybe when the gears are changes it will take care of it. Weather here has gotten things screwy so it may be next week before it is done.

did you put the factory size gears back in, or a different ratio ?

the 07s had a TSB for the clutch....do you know if yours was ever replaced?

Publication Date: July 28, 2008
FORD: 2007-2009 Mustang
ISSUE:
Some 2007-2009 Mustang Shelby GT500 vehicles may exhibit the following clutch/transmission symptoms: hard to disengage or engage 1st and reverse, hard to shift any gear, gear grinding during shifts any gear, vehicle creeps with trans in gear and clutch pedal fully depressed without brake pedal application, clutch slippage in gear with clutch pedal released, hiss noise with clutch pedal fully depressed (hiss on clutch pedal release is normal for GT500 clutch material). These symptoms may be due to flywheel distortion caused by excessive heat build-up during unique traffic conditions (example: severe stop/go urban driving). The distortion of the flywheel may prevent complete disengagement of the clutch. The system is designed for performance driving conditions.

Just had the clutch replaced for the infamous clutch drag. 28K mile car shouldn't have to have a new rearend and clutch.
