[QUOTE="gamatt, post: 15492614, member: 58764"] Ok so I bought by '03 with 35k miles and the pinion bearing was shot due to low fluid at some point, so i had a big nationally known Mustang shop rebuild it and put in FMS 3.73's. It was dead quiet for the first 3k miles but then started a whine on accel from 45-60 mph, then it comes back in around 80. It's not terrible and with the windows down and radio on you don't hear it. But I am going to start daily driving again soon, so I'd like to get rid of the noise. I suspect it has high teens in backlash, but there's only one way to find out. My question is, would it be worth the effort to remove the pumpkin and check it? I did the same thing in a sold axle foxbody several years ago, shifted some shims over to tighten up the backlash and it was dead quiet after that. [/QUOTE]
