Pinion Depth on 8.75 741 case

If you don't know the history of the gears, it's possible that if, they were not set up right by the first owner, or are old Zoom gears, you may never get rid of the noise.. Pattern "B" is perfect, if there're only slightly noisy at coast, turn up the stereo..

once had a customer come in with a set of 5:12s, when you took your foot off the gas, you'd swear there was a cop with a siren behind.. gears were damaged, and wouldn't shut up no matter where we set it..
