so last monday my car's rear end made a horrendous racket on the highway. i was going 70 in 6th. i have a 2011 GT, brembo, with a 3.73 rear end. my car had 1641 miles prior to the break down.

anyway after a tow to the dealership, they discovered a bad ring and pinion. looked like an assembly problem, according to the mechanic, and they order a new ring and pinion. ford over rode the order and decided to ship a whole new rear axle assembly.

while they had the car, i had the dealer replace the clutch assembly (correction: pedal assembly) as per TSB 10-19-4.

i got the car back today and drove it about 20 miles. first thing i noticed was that the clutch was much firmer. catch point was the same, as to be expected, but the pedal feel was stiffer, as if it had less assist. it might be all in my head, after 8 days without the car, but it felt firmer.

the 2nd thing i noticed was that the rear end whine (which i had experienced for a few hundred miles prior to my break down) was absent. i drove windows up and down in different speeds and gears. no whine.

so hopefully that's the end of my issues.

 

Congrats on getting your ride back.

 

Clutch TSB is for the pedal assembly, the new one has a stiffer feel, different return spring setup from my understanding.

 

oops, that's right it's the pedal assembly.

 

So you had the TSB done and a new rear-end? I think your problems are over, enjoy yourself

 

Yep, the TSB was the solution to the clutch sticking problem, and it basically was just a stiffer return spring so it could overcome that resistance. Out of curiosity though take a look at the pedal assembly, see if it has two springs on it. You'll either have a stock GT, a stock GT with two springs, or a GT500 assembly now I believe.

This post shows a stock GT clutch assembly and a stock GT500 clutch assembly, with pics!

The updated assembly is simply the stock GT with an extra spring in the same position as the GT500 spring.
