When I'm driving on the highway and I give the car gas, it pulls pretty hard to the right, but when I let go of the gas it's fine. I put my diff control on the furthest back position and it doesn't do it anymore. Any ideas?
Thanks

 

did you do that test at the same exact place? could be the road. what are your alignment settings at?

 

It does it everywhere, and what are you reffering to, caster, camber, toe in or toe out?

 

My swapped forester pulls to the left when I floor it and then when I let off and still have the wheel turned slightly to the right to compensate I go flying back over to the right. And just like in your case when I turned up my dccd it would allow it to pull straight. Does it do it in Auto mode? I only have the manual controller so can't see if auto corrects for this or not.

 

Yea. It only does it in auto mode.

 

On the off chance, have you checked your tire pressures?

 

Tire pressure and front end bushings. Check or replace those.

 

Torque steer?

Serious note, it's probably your tire pressure, alignment, and or worn bushings.

 

It was a combination of my bushings and tire pressure. Thanks!

 

Which bushings did you replace? control arm?

 

Bad outer tie-rod 'ball-joints' can also cause this issue along with the stated possibilities. My wagon was pulling to the left under acceleration, and wala it's the darn outer tie-rod joint flexing with tons of play.
