Steering is difficult when turning??

[Hummerguy32]

Okay my mechanic friend is going to do the pitman arm, idler (Both Moog), steering gear box, ohh and the Cognita Steering kit. Though this will cure that steering problem but my 4wd in the rear still feels like it's on. I tried that trick mentioned above though it still is doing this. What else can I do to resolve that issue w/ the 4wd?????
