Drivetrain Clunk

This noise I hear when braking or lifting off the accelerator is driving me nuts.
What can I do the eliminate it or at least minimize it? Suspension is now stock.

Any suggestions appreciated.


Thanks.

Re: Drivetrain Clunk

it won't be, unless you have a TON of miles. it's the 2-piece driveshaft. You can sometimes drive around this by revving the motor a little higher before shifting. Complain to Ford and they may give you another DS that's got tighter tolerances or go with a 1 piece DS from any number of vendors like DSS, Shaftmasters, etc.

Mine does this too. It has ever since day one. It feels like the play between the weight of the car in the nutural state, meaning no power to the wheels in between gears with the clutch in or between gears in an auto or leaving park. I don't think a one piece driveshaft will remedy this because I think it's just the way the car is built. It sounds like the noise is coming from the transmission itself and not the driveshaft U joints. I may be wrong for I am not a mechanic, just a random Internet guy expressing my opinion. My F150 does the same thing and I haven't had any mechanical issues due to this.

Usually when the 2-piece driveshaft (variations on this theme have been used in Mustangs since the Foxbody first came out) isn't responsible, it's slop in the rear end tolerances, which isn't easily curable without a new gearset with less tolerance stackup. Huge range of acceptable (meaning, no noise) levels of rear end slop in 8.8s.

My Mustang does that and my Moms Lincoln Aviator does as well.
