So here’s a weird one, I have a 99 GMC Yukon that I think might have a limited slip diff. Here’s where it gets interesting. When doing a burnout or when on slick surfaces, both wheels spin like an LSD or a welded diff would, and when I turn anymore that 3/4 of the way the truck handles like a welded diff (both wheels turn at the same or near the same speed making tight turns very rough). When I jacked the rear end up, the wheels spun in opposite directions like an open diff. The code stickers on the door and glovebox are gone. Can anyone help me out? Thanks.
