    I was changing lube in my 85 rear end and don't know what rear end I have. It has ten bolts for the cover, a gear or sprocket inside the cage on the ring gear side, little spools on the cage in front of the spider gears that have springs in them and they spin about ten times for a 1/4 turn of the ring gear. It does have clutches in it of course.
    Do I have a locker or what?
    Anyone with specs or an exploded view please reply.
    The reason I took it apart was because I felt alot of end play when I was putting on my new tires. By alott I mean about 3/16" just as an estimate, It seemed like alot but there wasn't any parts or shavings in the shell or in the old lube.
    Thanks,

    Sounds like a 10-bolt rear end with a Gov-Loc factory locking diff. They work great until they suddenly don't work any more. [​IMG]

    well you have a corporate 10 bolt rear end. thats what i have, most likely you don't have a locker but a limited-slip unless the previous owner put one in it. The gears (if they are factory) are probably 3.08's. The ratio is stamped on the ring anyway if you want to pull the cover off again.

    Sounds like an Eaton Gov Lock. Go easy on 'er. Big tires, burnouts on or off pavement=dead axle. Work fine as long as you don't demand much of it, such as extreme wheeling.
