rear end axles

I have an issue i was driving down the road and heard a pop. I had to reverse my yukon and then creep it forward to the house. I checked the rear end and theres a hole in the cover. I was wondering if it was worth pulling apart and looking through or if thats a sign the whole thing needs to be...

hello all, and happy new year to you i recently experienced a setback with my 1990 Suburban V1500 4X4 SLE i'm still not 100% sure what the problem is, but i'm looking into the potential costs of the various things i think it might be. i'm beginning to lean towards it's the rear differential...

I have a 2003 xl 4x4 that the rear wheels snapped off. Both axles are broke and it tore everything up back there so I'm think a salvage rear end would be cheaper than replacing all those parts. Will 2wd rear end fit or do I need a 4x4 rear end?
