I'm having problems with my suburban. Whenever I accelerate aggressively or maybe run through a pothole, my vehicle pulls to the right. When I straighten the wheel I can hear my drivers side tire squealing. I have to actually turn the steering wheel to the right so it would stop pulling. Do anyone have an idea on what's going on.

 

Could just be torque steer depending on how hard you're accelerating. May want to ease up on the gas.

I would also start with the tires checking for any uneven tire wear then try rotating them. If that doesn't help, probably would not hurt to get wheel balancing and alignment checked out either.

 

Torque Steer applies to FWD. not much in RWD.

I'd check the alignment.

 

Agreed but the OP mentioned hard acceleration so I at least had to throw it out a possibility.

OP - is your steering wheel off center too?

 

Maybe bad bushings in the upper or lower control arms??? I'd take the front wheels off and do some inspecting. See if anything is loose.

 

agreed; Bushing / wear items / etc.

lift it by the frame, and grab + shake the wheels. if they move, something's wrong

 

to check short long arm suspension systems you must unload the lower ball joint...so place your jack or jack stand as far out as possible under the lower c/a...then do your wheel shake.
