Front diff binding on D30...

On my buddies 78, his front diff is acting funny. We were hearing a poping noise when the hubs were locked. When we pulled the cover, I could see that the very edge of all the teeth on the ring were freshly ground off a bit. I looked and there really wasn't any clearence inside the pumkin. It only does it in reverse though. We jacked up the front wheels and turned the front wheels in reverse and it locked the gear up. It looks like its rubbing into the housing on the bottom of the housing. I don't know exactly what all the parts are called, but the bearing cap on the passenger side was not flush with the housing, as the one on the drivers side seemed to be. We're both pretty wet behind the ears when it comes to this aspect of the Jeep, so any help would be appreciated.

Thanks,
Sean

Re: Front diff binding on D30...

Without seeing it in person, my first guess would be bearings.

Take two bars or big screw drivers and try to pry the carrier back and forth or even up and down. If it moves alot there are bearing problems. Actually any movement is a problem. But a small amount of side to side movement wont cause what you are talking about.

Also while you are under there, grab the pinion yoke and try to move it side to side, in and out, and up and down. If it moves there are problems.
