Questions to Ask About a Wheel-Alignment Quote and Report

Before you approve a wheel-alignment quote, ask three things: which type of alignment is being quoted, what the price includes and excludes, and whether you will get a printed report showing measurements from before and after the adjustment. Wheel alignment means adjusting the angles at which the wheels sit relative to the vehicle and to each other. It is a different job from wheel balancing, which corrects uneven weight distribution around a wheel and tire. The right questions depend on your vehicle. The angles that can be adjusted, the specifications the shop works to and any follow-up calibration all vary by make, model, model year and equipment, so the answers have to come from the shop and the manufacturer's data for your car, not from a general guide.

Terms you will see on a quote or report

• Toe: whether the fronts of the wheels point slightly inward or outward when viewed from above.
• Camber: the inward or outward tilt of the top of the wheel when viewed from the front.
• Caster: the forward or rearward tilt of the steering axis when viewed from the side. It affects steering feel and self-centering, and on many vehicles it can't be adjusted without extra parts.
• Thrust angle: the direction the rear axle points relative to the vehicle's centerline. If it is off, the vehicle can track at a slight angle even when the front wheels are set correctly.
• Specification (spec): the manufacturer's target value or acceptable range for each angle on a given vehicle.

Questions to ask about the quote

• Is this a front-end, thrust-angle or four-wheel alignment? A front-only job adjusts the front wheels. A thrust-angle alignment sets the front relative to the rear axle without adjusting the rear. A four-wheel alignment adjusts both axles where the vehicle allows it. Ask which one suits your vehicle's suspension and why.
• Which angles on my vehicle are adjustable, and which will only be measured? Some vehicles have limited factory adjustment. If an angle is out of spec but has no adjustment, ask what the options are and whether they cost extra.
• What exactly does the price cover? Quotes often break down into labor, equipment use and any additional services or parts. Ask whether the price is a flat rate or could rise.
• What could add to the cost? Seized or corroded adjusters, aftermarket adjustment kits such as camber bolts or plates, and worn steering or suspension parts are common reasons a final bill differs from the quote. Ask the shop to contact you before doing any work beyond the quote.
• Will the steering and suspension be inspected first? Worn components can prevent an accurate alignment or let it drift soon afterward. Ask whether an inspection is included and how findings will be reported.
• Will tire pressures be checked and set before measuring? Pressure affects ride height and the readings.
• Does my vehicle need any calibration after the alignment? On some vehicles, the manufacturer requires a steering angle sensor reset or calibration of driver-assistance cameras or sensors after alignment work. Whether this applies depends on the vehicle and its equipment, so ask whether it applies to yours and whether it is included in the quote.
• Does the quote include wheel balancing? Many shops sell the two together, but they are separate services. Confirm which one you are paying for.
• Is there a warranty or recheck period, and what are its conditions?

Questions to ask about the alignment report

An alignment report, usually a printout from the alignment machine, is the main evidence of what was measured and changed. Ask for one whether the alignment is paid or offered free, for example as part of a tire purchase. Without before-and-after figures you can't see what was wrong or what was corrected.

• Does the report show both before and after readings for every measured angle on each wheel?
• Does it list the specification range for each angle, and is it clear which readings were out of range before and which are within range after?
• Is the correct vehicle identified on the report? Specifications depend on make, model, model year and sometimes trim or suspension option. A wrong vehicle selection means the shop worked to the wrong targets.
• Where does an angle remain outside spec afterward, does the report or the technician explain why? A missing adjustment or a worn part are typical reasons.
• Were any parts replaced or adjustment hardware added, and is that recorded?
• Are ride height or other measurements noted when the vehicle's specifications depend on them?

Alignment versus balancing

Aspect | Wheel alignment | Wheel balancing

What it corrects | The angles of the wheels relative to the vehicle and to each other | Uneven weight distribution around a wheel and tire assembly

How it is done | The suspension and steering linkages are adjusted to bring toe, camber and, where possible, caster within spec | The assembly is spun on a balancing machine and small weights are added to offset heavy spots

Symptoms commonly associated with it | The vehicle pulls to one side, the steering wheel sits off-center, or one edge of a tire wears faster than the rest | Vibration that often changes with speed

Documentation to ask for | Before-and-after angle readings with the spec ranges | Confirmation of which wheels were balanced

Symptoms overlap and can also come from tires, worn components or other faults. A pull or a vibration does not by itself show which service is needed. Ask the shop to explain how it diagnosed the issue before quoting.

What this guide can't answer

This guide does not give prices, alignment specifications, service intervals or conclusions about whether a particular vehicle is safe to drive. Those depend on the vehicle, its condition, local labor rates and the manufacturer's service information, and no verified figures were available for them. For specifications and any required calibration, rely on the manufacturer's data for your exact vehicle, as presented by the shop or your owner's documentation. If you are concerned about how the vehicle handles, have a qualified technician inspect it.

Next step

When you request the quote, say up front that you want the alignment type stated in writing, a call before any extra work, and a before-and-after report showing the spec ranges. If you are comparing shops, compare quotes for the same alignment type and the same inclusions, such as inspection, calibration and balancing. Otherwise the prices aren't comparable.
