I was out bashing today fairly lightly. No jumps or doughnuts or anything stressful on the drive train. Noticed the back differential locked up and only the front wheels will turn. Everything else looks fine. No stripped gears or metal in the diff housing. It appears to be a missing set screw. If anyone can confirm that would be greatly appreciated.

WHEN YOU SAY "LOCKED" DO YOU MEAN NO DRIVING POWER TO REAR WHEELS OR REAR WHEELS DON'T TURN AT ALL ?

The wheels would spin (opposite directions like normal,)but the diff wouldn’t. As a test, I placed a similar diameter pin in the hole and everything seemed to rotate and function as normal. I didn’t have driving power but the wheels would spin fine by hand. I ordered both 86094 and 86095 just to be prepared for the future.

See the pic of the grub screw needed, it lines up with a hole in the shaft and drive cup unit, even has a part number for reference also don't forget to add a drop of locktite blue to the threaded part ..
