Sounds like traction control, or lack of traction control.
I'd be more worried if it only pulled to one side.

I'd have to find the page I copied from Mitchell to get specifics. In 4A, it uses a feature they call "torque anticipation." Under hard acceleration from a stop, it "anticipates" the possibility of the wheels slipping, and sends power to the front. The "jerking" your feeling could be from the front wheels slipping (are they spinning when it does this?). If you have traction control, that could also be contributing, as the brakes are applied to control the front spinning. All of these explanations depend on the conditions being right for the front end to spin. Mine doesn't do anything funny if the front wheels don't spin.
Does it do it in 4H or only in 4A?'98 K1500 Suburban LS 5.7 L 4L60E NV246 ARB

every truck will do this just like a front wheel drive car will if you are mashing it in 4wd, you shouldnt be accelerating that hard in 4wd anyway, it will fail quicker especially when using 4wd auto, you are essentially binding it up as the tires are momentarily spinning and then the computer is engaging the 4wd.99 K1500 Suburban LT "THE BEAST"

it doesnt seem to be as bad in 4h . Im not mashing it just about quarter throttle . if its on snow and the wheels can slip it doesnt do it just on pavement when the wheels have traction[/SIGPIC]2001 gmc 1500 ex cab,3" body lift,3" leveling kit,315/75/16 hancook dynapro mt's, punched cats, custom flowmaster exhaust, k&n with custom intake,camo kit, Dual trumpet air horns,Siren, Custom camo interior LIFT IT FAT GIRLS CANT JUMP
