2011 Lexus IS 250 RWD, Got all 4 tires replaced and alignment done at the dealership. Now the the car drifts to the right. There is .1 degree difference in caster from side to side (7.2 left, 7.3 right). Is this difference enough to cause a drift to right even if the caster is lower on the left? Below is a picture of the before and after alignment specs. Does the specs look right?




Thanks in advance.

 

What does the alignment shop say? Sorry I don't know ho two read those.

 

Same thing happened to me. My drifting issue ending up being fixed with an adjustment to the front cross member I believe. I'd not worry about those very minor caster specs in the red. As you can see, they're VERY close to spec. The best thing is to ensure their even, or as close as possible to even.

 

You might need to install ball joint to correct alignments.

 

^ What "alignments" are you going to correct with "ball joint"?

 

My mechanics recommended for the front.

 

My point is if you don't know what you are going to adjust, there is no sense in throwing new parts into the mix.

Adjustable ball joints on the front will add the ability to adjust the camber. Camber in the above sheet is absolutely fine so adding the ability to adjust it won't help.

 

My mechanics will install ball joint to correct negative chamber. He also have machine for alignment in front.
