10 bolt

  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...

    I've got a 79 nova, hasn't been on the road since '98 and last week first time driving it since spending 4 years rebuilding it. Was told it used to drag at a local 1/8 mile.

  6. 8.5" 10 Bolt Open vs. Posi Spider Gears

    Drivetrain & Performance
    Hello everyone, I purchased a 8.5" 10 bolt a while back with posi and 4:56 gears; the spider gears in the posi need to be replaced, there is a big chip in one of them. Everywhere I look it seems you can only buy spider gears for open rear ends only. This may sound like an ignorant question...
