[jeeper05]

hey everyone just a quick question!
when i let off the gas the jeep pulls to the right... when i accelerate the jeep pulls to the left i was wondering what could cause this..it has a 4inch lift and 33s on it i was thinking it could possibly be the suspension but not sure..
thanks for and knowledge

Motor mount maybe?

Definitely a suspension issue. I'd start with the rear axle on the left side. Something is moving around when you accelerate/decelerate.

It does sound like something might be loose or possibly binding. Start with bouncing each corner to check for a binding shock absorber.
Have someone sit inside and hold the brakes on hard while loading the driveline in drive or reverse while watching the rear suspension and axle for movement. Look under the hood and trans for the mounts.

I'd swap the tires left to right to see if its a bad tire. the pull will change if so.

These are all good places to start. I would also check tire pressure. Once the obvious and simple are elliminated.
Im going with bump steer. Youve got a lifted Jeep. I cant say if youve addressed the track bar or pitman arm with the lift or not but what can happen if you dont is that the track bar and drag link wont be parallel to each other. When you accelerate, the front of the jeep comes up which will actually pull the axle to the drivers side causing it to pull left. The opposite happens when you brake or slow.
Is the lift new? Did the pulling first appear after the lift?
