Ok, I'm new here and I have an issue I've never seen before.
I have a 2000 Chevy GMT-400 k2500 LS that doesn't get any power to the rear drive shaft. The weird part is that it still drives in 4Lo. It only provides power to the front wheels, only takes off after 1000-1500rpms, and isn't really a smooth ride.
It doesn't even take off in 2Hi or 4Hi. What I need to know is if anybody has seen this before and knows where this could be coming from. I'm thinking transfer case, transmission, or the 4x4 selecto switches.
To my knowledge this truck is supposed to be mainly powered by the rear wheels so why do I only get power to the front?
Note: I know it's getting power to the front because I've driven it without the rear drive shaft being connected at all. When I put the rear drive shaft back on, it drove exactly the same. I just figured if I had a bad transfer case, the front wheels would be the first to go out.
Please help
