Okay so I jacked up my 2001 Chevy Suburban off the ground and put it on jack stands I put the car in 2 wheel drive and the drives the rear drive shaft with spin but the tires will not spin so I put the car in neutral then put it in 4-wheel drive then put it back in drive the front wheel spent the rear driveshaft spent but not the rear tires any idea on what it could be please help

 

Took out the rear differential?any noise before?

 

+1
pull the diff cover and inspect

 

@ geo 1 it was doing popping sounds when i turned

 

@tech2 what should I'm looking for

 

You shouldn't have to 'look' for anything. Popping when turning, driveshaft spins but wheels don't. My only advice is try not to let any of the gear/bearing carnage hit you while removing the cover.

If a differential rebuild is not something you are willing to do yourself, save yourself the time and mess for the person/place who will be doing it.

 

If the rear drive shaft is spinning but the axles aren't you have a bad differential. The 9th gen differentials were an issue. Mine was rebuilt about two years ago. It's not real cheap to get it done so, shop around. But, it's worth it. It's not a job that a novice can do. It takes an experience mechanic and special tools to overhaul a diff.

 

yeah that's what I was planning to send it to a shop and let them do it and I'll just wanted to be sure that's what it was before I sent it because I didn't had other guys tell me that it was a whole lot of different other stuff that had nothing to do with my rear end it was all front end like ball joints and tie rods and talk about that's what was popping when I was turning and it turns out that wasn't the case my rear axle was going out all the differential case whatever you want to call it I just wanted to troubleshoot for myself but thanks for the advice and information it was truly valuable thanks to all the guys deceptive dick head up above talking about gears hitting people in the face but everybody else I appreciate your input and help
