Drivers often assume that if a car still tracks straight after a small crash, nothing important has shifted.
Modern suspensions are more precise than ever, and even a gentle nudge can alter angles that keep tyres gripping properly and steering responses predictable. Alignment is the first place where small impacts leave clues.
Alignment is a collection of angles that guide how tyres meet the road. When those angles drift, the changes can feel subtle. A car may wander slightly on the freeway, sit a little off centre at the wheel or follow ruts more than usual. These changes often appear weeks after a crash as tyres wear into a new pattern.
| Area checked | What technicians look for | Why it matters |
|---|---|---|
| Suspension arms | Small bends or stretched bushings | Even tiny changes alter camber and toe |
| Subframe position | Evidence of movement at bolts | Shifts cause steering wheel offset |
| Steering components | Tie rod distortion or play | Direct impact on steering accuracy |
| Tyre wear | Uneven edges or feathering | Shows how the car has been running since the impact |
Alignment does more than preserve tyre life. It shapes how electronic assistance systems behave. Lane keeping, stability control, adaptive cruise and parking systems all read off the car’s geometric baseline. When that baseline changes, the software compensates in ways drivers can feel.
A small shift in toe angle, for example, can create:
