The bay must provide a stable, repeatable reference while allowing the vehicle suspension and wheels to move as the alignment procedure requires.
A stable lift is part of the measurement system.
Turn plates and slip plates must move correctly.
Cameras need clear target visibility.
Runout and caster procedures need space.
Floor and lift stability
Movement in the floor, anchors, lift structure or runways can change the relationship between the vehicle and measurement system.
Wheel support and suspension settling
Turn plates allow steering movement. Rear slip plates allow suspension and toe changes to settle without binding. Locked, dirty or poorly positioned plates can influence adjustments.
Visibility and working space
Cabinets, posts, vehicles, technicians and open doors should not block the camera view. The bay must also allow the selected compensation method.
Bay condition checklist
- Floor and anchors stable
- Lift runways verified
- Turn plates clean and free
- Rear slip plates operating
- Target view unobstructed
- Runout and steering space available
Bay diagnosis questions
| Question | Why it matters | What to confirm |
|---|---|---|
| Do readings change when the lift moves? | May indicate structural or reference movement. | Lift locks, runways, anchors and calibration. |
| Does toe change after plates unlock? | Binding may have held the suspension. | Turn plates, slip plates and wheel chocks. |
| Are targets partly blocked? | Lost image data can interrupt or reduce measurement confidence. | Cabinet, vehicle body, technician and camera position. |
Frequently asked questions
Can alignment be performed on any vehicle lift?
The lift must be suitable for alignment and compatible with the system and vehicle range.
Do dirty turn plates matter?
Yes. Contamination can restrict movement and prevent the suspension from settling naturally.
Can short bays use different runout methods?
Some systems support alternate methods, but the selected procedure must be approved for the configuration.
