Hard accelerating problem

My problem happens only in first gear when starting hard from a dead-stop, and also when moving 20-30 mph and then press gas pedal hardly. Then Jeep is jumping and vibrating 2-3 seconds or until I let off gas... I posted video of my rear driveshaft, is everything ok here?:

P.S. Sorry for my bad english : )

Re: Hard accelerating problem
hopefully one of the WJ guys can chime in but in mine it was the TCM and torque management system

Re: Hard accelerating problem
yo bro i had a similar problem with my jeep but i have the 2002 4.7 but anyway when i was driving i would have horrible acceleration so what i eventually did was clean my throttle body and also clean my IAC senors which is on the throttle body.. im not totally positive this could fix your problem but its very easy to clean and who know this could be a simple fix
