Just installed my 4.10s .. Now everything felt fine and double checked everything.. Now there's no noise at all until deceleration and is the loudest from 50-35.. Now when I push in the clutch it goes away the gears are ford racing I checked the serial number it ends with an A will they whine go away?? After some miles are put on or am I screwed? If it gets louder I'm gonna check the slack side to make sure the wears good I just hope the noise goes away

Gear whine will not go away. Once the pattern sets in, that's pretty much it and that starts once you drive the car. Make sure you go through the cool down periods and slowly wear in the gear though.

Damn it!! I'm gonna try and set the slack side better I can't remember are the shims behind the bearings? Or where?

If you have gear whine the install is wrong sorry bro

What was done wrong?

I have a similar prob....checked and rechecked backlash, said it was OK....changed gear oil after break in....still hava lil noise

Mine is not really a whine, but def a noise on the DE Cel side at around 40mph

No whine here but I got mine done at a shop that works on Mustangs only. And the guy that did my install does the gears for the shop.

See that's what I don't get... Cause everything was put back right the back lash is set good.. The pinion is sitting right in the middle there's not to much play it just doesn't seem like it was done wrong..

Same here.......

Mine was done by a Mustang Mech who has done a hundred of them.....wierd and a bit annoying.....

Is the car lowered? That might have an effect on the pinion angle.

I'm on my second set of gears, both were ford racing 3.73, this set is alot quieter than the first. Not silent but not noticeable unless you listen for it. I was told that a 1 piece DS might help also. Good luck.
