Rear End Failure/Replacement Thread

If anyone has seen my threads lately you know my rear end was making a very bad noise and I finally had to replace it.

I finally took it apart and here are my findings. similar to what everyone else with failures has found.





As you can see, the pin slid out and was bouncing around. It looks like the set screw that holds the pin in place backed out and let the pin fly free. This did not cause complete failure, and all the gears are still in good shape. I'm going to replace the housing and the pin and it will be in great working order again.



Anyone else with rear end problems please post.


Thanks!!

I had my rear end replaced but was told the pinion gears were broken and lead to further damage. I was never able to physically see it or pictures as it was done under warranty.

MAkes me very curious. Mine would be a simple fix if I had caught it early, just a new set screw and your good to go.

Mine is exactly like your pic. The holding pin snapped allowing the main pin to slop around. Now to figure out who to have fix it.

I got one out of a junkyard from car-part.com for $1800 and spent 8 hours putting the whole new rear assembly in. Not a hard job, just takes a while!

Throw that in the scrap pile and get an auburn LSD or an arb locker.

That large pin in the center of the differential has slipped downward and the end has been getting destroyed from hitting things while spinning. At some point it will fall more and either lock the axles up, or (most likely) it will will grenade the center section completely.

It would be where it is, just not poking out at either end.

The pin retains the spider gears and is(should be) retained with a small bolt.

Here is/was mine sitting on the bench from my LSD install
