Alignment issues?
 

Hey guys,

FR-S seems to lose alignment a week or two after it had been re-aligned. This is third time. Daily driven, not abused at all. All stock.

I will take it in for alignment, 2hrs or so later, come pick it up, drive it a week or two, then it pulls to right (iirc). Then I repeat the process of taking it in again every 3 weeks ($100/visit) or so. This is gonna take its toll on my wallet. Tires @ 90%+ thread, brand new. No rim wear/deformation.

Anything I can check or that you guys would recommend/have had similar issue?

Thanks.

Blown shock or bad wheel balance can be a possibility. Air pressure also.

I agree on the shocks being an issue or the wheel balance being an issue but not tire pressure because normally tpms can detect a dangerous variation. I would honestly go to a reputable Toyota dealer and say the car is continually losing alignment, it could probably even be a defective alignment rack or them not aligning to spec. Stop wasting money on alignments because the problem keeps reappearing go to a dealer that knows what there doing.

talk to your alignment shop about this. if it's a reputable shop, they should be able to figure it out and won't charge you if you have just recently gotten an alignment even more so if you've gone there multiple times within a short period.

What setting(s) is drifting on the alignment? Are they actually showing you the specs before/after, or just saying they fixed it?

The only adjustments stock are toe, and front toe is VERY unlikely to "slip" unless you hit something, which really only leaves the rear toe. It shouldn't be slipping at all without a major impact or serious abuse though.

It could also be tire pressure, the TPMS system lets you have a ~5psi variance before it turns on the light and that's enough of a difference that it could be felt like this.

But man, 5 psi under for 3 weeks+ someone probably purposely leaked air out of the tires
