Hey guys, my S is been doing this, only pulls pretty hard under acceleration, ones i let go the gas its straight, car just left the aligned shop, they say they have no idea why it keeps doing that, everything is within specs. I would add that even though, i don't know if this was happening before or not (at least it was not noticeable before), this got very noticeable as soon as i got a set of "used" tires, Could this be the problem? has this happened to anybody? any idea why this would be?
im scared to think it is the diff. or something in there..

Thanks for your input

 

Check tire pressure or uneven wear on the tires. Most like the tires are the issue one way or another.

 

i had a 2006(silver in my avatar) and this was something I noticed, it was 100% bone stock with the factory tires, bought with 0.4 miles on the ODO from the showroom floor. Only under harder acceleration. My 2001(yellow in my avatar) does not do it at all

 

Yeah, pressure is even and to spec, uneven wear, Possible. i really hope its just the tires, what am going to do is rotate them left-right or even front back, (momentarily for testing purposes) and see if it pulls to the other side?

 

It is 100% the tires.
Size, brand, age, wear, and pressure must be an exact match.

 

I thought there were issues with mounting rears into the front.

 

Mine did this. Got new tires, correct pressure and doesn't do it.

 

maybe the used tires on the left vs. right side are slightly worn differently. Had this happen in the past when there was more tread on one side

 

Yes, still haven't gotten new tires, but did rotate the rears side to side, and yes it pulled to the OTHER side!

 

wouldnt rotating the rear tires side to side defeat the purpose of them channeling out water?
