Does a wheel alignment include the rear wheels? It should include checking them, but whether they can be adjusted depends on the vehicle’s suspension. For Burlington, Wisconsin, drivers comparing alignment appointments, the key is to ask whether the shop will measure all four wheels and which rear adjustments the vehicle allows.
Measuring all four wheels does not mean adjusting every wheel. A vehicle can need rear measurements even when its routine alignment adjustments are limited to the front. I-CAR recommends considering all four wheels and steering wheel position regardless of rear suspension type. I-CAR’s alignment guidance explains why rear readings matter.
What does a four-wheel alignment include?
Two separate tasks are involved: checking wheel angles against the vehicle manufacturer’s specifications, then making the adjustments the design permits and the readings call for.
Specialty Products Company distinguishes these alignment procedures:
| Procedure | How the rear wheels are involved |
|---|---|
| Front-end or two-wheel alignment | Aligns the front wheels to each other without accounting for the rear axle’s position. |
| Thrust alignment | Measures all four wheels, then adjusts the front relative to the rear wheels’ direction of travel. |
| Four-wheel total alignment | Measures all four wheels and adjusts both axles on vehicles with the necessary adjustment provisions. |
A solid rear axle commonly calls for a thrust alignment because routine rear adjustment is unavailable. Adjustable independent rear suspension permits a four-wheel total alignment. Additional parts may be necessary on some vehicles. These distinctions come from SPC’s consumer alignment guide.
When booking, ask what the procedure includes for your specific vehicle. The appointment name alone does not tell you which rear angles can be changed.
What determines whether rear wheel alignment is adjustable?
The rear suspension design and the manufacturer’s service procedures determine the available adjustments. The technician can check an angle even if there is no factory provision to change it.
Many independent rear suspensions allow rear toe and camber adjustment, but the provisions vary. One vehicle might permit adjustment of both; another might allow routine toe adjustment without a routine camber adjustment. Both angles can still be checked.
Most solid rear axles have limited or no simple rear adjustment. Their readings still matter: setting the front without accounting for the rear can leave the steering wheel off center or contribute to a pull. I-CAR also cautions that a rear thrust angle outside specification needs correction before completing alignment. Its explanation covers both suspension types.
For example, a report showing rear measurements alongside front adjustments can be appropriate for a solid-axle vehicle. The useful follow-up is whether those rear readings meet specification and, if they do not, what the technician found.
What if an unadjustable rear angle is outside specification?
“Not adjustable” describes the available adjustment provisions. It does not mean an out-of-specification reading can be ignored.
The next step is diagnosis using the manufacturer’s procedures. MOOG recommends checking for worn or damaged steering and suspension components, as well as replacement parts that may not match original specifications, when proper alignment cannot be achieved. Suspect components need attention before the alignment is repeated. See MOOG’s guidance on limited-adjustment vehicles.
On a solid-axle vehicle, an abnormal rear reading can point to bent suspension parts or structural damage. The reading alone does not identify a failed component; ask for the inspection findings that explain the recommendation.
Some applications have correction parts that add adjustment where factory provisions are limited. That is a vehicle-specific possibility, rather than something to assume is included in a routine appointment. Ask whether the proposed solution follows the applicable procedure and whether it requires a separate quote.
Ask the technician to show you the reading outside specification and explain what is needed to correct it.
How should you discuss the rear readings?
Ask the technician to separate the measurement result from the work performed. For each rear angle, useful questions are: Was it measured? Was it within the manufacturer’s range? If it was outside that range, was an adjustment available and made?
Consider a vehicle with adjustable rear toe but no routine camber adjustment. If the shop says it “adjusted the rear,” ask which angle it changed and what the remaining camber reading means. That wording could describe the available toe adjustment without explaining whether camber needs further attention.
For a vehicle with no routine rear adjustments, ask the shop to distinguish between rear measurements that meet specification and readings that still need diagnosis. “We only adjusted the front” leaves that question unanswered. Request an explanation of the rear results rather than assuming that no adjustment means no check was performed.
If additional work is proposed, ask for the recommendation in writing before approving it. Have the shop identify the finding behind the recommendation and explain whether the proposed work is needed before alignment can be completed. Clarify whether the revised quote includes the parts, installation and subsequent alignment work, or whether those are separate items.
Keep the before-and-after report with that explanation. The readings and the technician’s notes should help you understand what was checked, what was changed and whether anything remains unresolved.
What should you ask before booking?
Performance Tire & Auto Service advertises wheel alignment checks in Burlington. To clarify what your appointment will cover, give the shop your vehicle details and ask:
- Will you measure all four wheels? Ask specifically whether the rear readings will be included even if the rear has no routine adjustment.
- Which rear angles can be adjusted on my vehicle? Ask the shop to distinguish factory adjustments from corrections requiring additional parts.
- What does the current quote include? Request a vehicle-specific quote from the shop and clarify whether it covers measurement and the available adjustments.
- What happens if a rear reading is outside specification? Ask how inspection findings, proposed repairs and additional charges will be explained before further work.
- Can I receive before-and-after readings? Ask for the rear results as well as the front, with an explanation of any angle that remains outside specification.
Also clarify whether you are requesting alignment or tire rotation. Rotation moves tires between positions; alignment addresses wheel angles. The shop’s guide to how often to rotate your tires explains that separate maintenance task. A rotation appointment alone does not answer whether rear alignment angles have been measured.
