    have you checked the pinion bearing, carrier bearing in the d shaft or the gears themselves?

    Yes it should not move like that(it shouldn't move at all). Has the pinion but backed off at all? There shouldn't be that much slop without something coming loose.

    Yes, its possible, if it came loose its probably too late to just tighten it up though. Sounds like you gonna need a diff rebuild. Depending on what gear you have might be cheaper to find another third member.

    I had a noise in my '01 like what you describe. Iput it on 4 jackstands and crawled under it with an engine stethescope. Once I touched the pinion bearing area with the scope I heard he growl immediately. Needed a pinion bearing. Fortunately Ihad the means to rebuilt the centersection myself. I put all new bearing races and seals in that bad boy. I think it was around $250?, for all the parts if Iremember correctly. But that's been a while ago so I could be off on the parts number.

    At any rate, check the wheel bearings, and work your way in to the center section and possibly U joints.

    Good Luck!
