After work intended to address a car that drifts on a straight road, repeat the original conditions in a safe place and check whether the symptom returns. Test on a level, safe road and note wind, road crown, braking, and tire pressures. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Check tire pressure and wear before assuming alignment is needed. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
