An alignment report is a technical record of the selected vehicle, measured geometry and final result. It is most useful when the technician can explain what changed, what remained diagnostic and how the readings connect to the customer concern.
Confirm the vehicle information before reading the numbers.
Before values document the condition; after values document the completed work.
Colors summarize tolerance but do not replace diagnosis.
Cross, total and thrust values often explain the relationship between individual readings.
Vehicle and job information
Start with the report header. Confirm year, make, model, suspension package and any ride-height or load selection. Check that the units are understood: degrees and minutes, decimal degrees, millimetres or inches. An accurate measurement compared with the wrong vehicle data produces a misleading report.
A useful report also identifies the date, technician, work order and vehicle identification information. These details support future comparison and warranty documentation.
Before and after columns
The before column records the measured condition after inspection, compensation and the required sweep. The after column records the final condition after adjustment, tightening and settling. A value may remain unchanged because it is not adjustable, because repair was declined or because it was already acceptable.
| Report element | Question to ask |
|---|---|
| Before value | Was the initial measurement stable and taken in the correct condition? |
| After value | Was it rechecked after tightening and settling? |
| Preferred value | Is this the nominal target for the exact vehicle? |
| Min / max | Is the final value inside the approved tolerance? |
| Color | Does the color reflect the correct units and selected specification? |
Total, cross and thrust values
Total toe shows the combined toe of an axle. Individual toe shows how that total is distributed. Cross camber and cross caster show left-to-right differences. Thrust angle shows how the rear wheel directions relate to the vehicle centerline. These relationship values often explain steering-wheel position and directional behavior better than one isolated reading.
Diagnostic values that may remain outside range
SAI, included angle and setback may not have normal adjusters. If they remain outside range after the repair, the report should be supported by an inspection finding or recommendation. A technician should not hide a diagnostic condition by forcing an adjustable angle away from its proper target.
Similarly, a value can be green while the vehicle still has a tire-force pull, brake drag or steering concern. The report supports the diagnosis; it does not replace the final road test.
Explaining the report to the customer
- Begin with the complaint and the tire condition.
- Show the rear condition before the front because it establishes the vehicle direction.
- Explain what was adjusted and what was inspected.
- Use plain language for toe, camber and steering-wheel position.
- Identify non-adjustable values that require repair or monitoring.
- Provide the final report and tire or component photos where useful.

Frequently asked questions
Why can a final value still be red?
The angle may not be adjustable, the adjuster may be at its limit, a repair may be required or the customer may have declined additional work. The technician should document the reason.
Does a green report guarantee the vehicle will not pull?
No. Tire force, pressure, brakes, road crown and steering systems can influence direction even when alignment values are within range.
Which report values are most important for steering-wheel position?
Rear thrust angle, front individual toe, front total toe and steering-gear center are especially important.
