  1. Rear end whir during heavy braking

    Drivetrain & Performance
    I rebuilt my 8.2" 10-bolt on my 70 with new gears and Yukon LSD. It has about 100 miles on it now. During hard braking there is a whir noise like there is a flat spot on a bearing. No other noise during cruise, coasting, accel or deccel. Here is a picture of the gear wear. This is my first diff...

  4. 12 bolt posi rear end - How much and which gear oil?

    Drivetrain & Performance
    I've read on line that a completely dry and rebuilt 12 bolt rear end will take up to six quarts to fill. I thought that must be a typo and they must mean six pints but they swear it's six courts. I thought it only two or three quarts but I'd like to be sure at $28/quart. Since I spent $2k on...

    Drivetrain & Performance
    I've got a 1963 nova with a 3.08 open/non-posi. I'm having axle bearing problems and I was wondering if I should replace the carrier and do the bearings all in one shot or just do the bearings and drive it till it pukes. It's hard to find a quality diff that fits my car. I found a 3.08 posi...
