Hi, i own a 2000 mustang gt 5-speed, i just about have 89k miles. When im turning slowly as im easing up on the clutch i hear a somewhat grinding noise from what i think is from the differential. this noise doesnt happen consistantly but concerns me. but im not sure if this is related but when i go all out on my car it seems like the power isnt getting to the wheels, and my gas millage is horrible. could this be a floating axel shaft or just a bad rear end?

Thanks,
Jeff

it's the limited slip clutches. you need to take the cover off and check the condition of the side gears to. The kit to rebuild the LS is only about 40 bucks or so. if the side gears are damaged just get a whole carrier out of a junked car/truck with 8.8 unless you want to swap to 31 spline axles make sure you get a 28 spline carrier.

diff, (groan)

I've got a 2000 5spd gt also, with only about 35000 miles on it (it's my toy) and when it is warmed up, the diff grumbles and groans in low speed turns. cluch in or out makes no difference. Dead quiet for the first couple miles. can't believe that the cluches are worn, I can still leave 2 black stripes whenever I want . Gonna try changing the fluid, and take a peek here soon, and see if that changes anything. I have had 3 other cars with the track lock diff, and never had one do this before (I've smoked 1 before tho) hope 2 find an ez solution, or just throw in a spool!

it's not the clutches being worn out that cause the noise. it's the clutches working too good! so you will have very good posi. but it will make noise.

there is a tsb on i very very common problem.

you may get lucky and get the noise to stop when you change the fluid. in fact thats the first step ford wants us to do for the tsb. then if that don;t fix it we replace the clutches.
