If it's alot then really work on fixing it also check to see that the side belt is engaging because this sound like more than tweak it sounds like something in the drivetrain.
What's a lot?
Before any adjustment (all shock collars set the same for ride heigth) one rear wheel lifts at most about a 1/16 of inch before the other side. I can adjust it out to where both wheels lift equally with several turns of the opposite front shock or visa versa.
I tend to agree with you about it being something more than tweak. I'm going to check all the pulleys and make sure they are the right teeth for where they are. The side belt is definitely engaging because I do get power to the front wheels. I'm just not sure if its equally between the two front wheels. That's why I want to put back in the solid axle. That should correct the on power problems. I know its not the rear diff, it's a gear diff and is in very good condition and feels real good.
I want to rule out shocks and tweak tonight, I hope.
