Has anyone else experienced this. From a dead stop accelerating hard to almost WOT somewhere around 15-20 MPH I feel the vibration on my leg which rests against the parking brake handle.

Is your GT an automatic? If so, a few of us have had a problem with a momentary shutter felt in first gear when pulling away from a stop. It happens at about 2K RPM and is felt in the seat and the e-brake handle. We've had some success by having the drive-shaft replaced under warranty - in my car and at least one other, the shutter has been significantly reduced but not totally eliminated. It seems some of the drive-shafts are "tight" (Ford engineer's term).

The replacement drive-shaft is the same part number as the original. Apparently, some drive-shafts in the production run came out "tighter" than others. The dealer tech told me the Ford engineer said the tight drive-shafts do check out OK on the test bench, so getting a good replacement is basically a crap shoot. My advice is to take it to the dealer, demonstrate the shutter and mention the drive-shaft problem. If the dealer calls Ford tech, they'll probably tell them to replace the drive-shaft. Hope this helps.

Thanks for the info. It is an auto. I will have them check it out. I think your right with the RPM range. I will pay more attention tomorrow when I take the car out.

I just had my gears replaced from a 3.31 stock to a 3.73. They used FRPP 3.73 gears.

I got the shudder you mention. I didn't have it until the gears were replaced. Oddly though, they didn't drop the driveshaft to replace the gears.

I took it back and they did something to the driveshaft. They told me it was a 2 piece driveshaft so they "phased" it.

I still feel a bit of shudder still. I'm going to drive it some more today and then if it still acts up, take it back.

Thx,

Mike

How do you change rear end gears with the drive shaft attached[sm=dontgetit.gif]
