Can you align just two wheels?
Yes. In many cases you can perform a two-wheel alignment (front-end alignment) on a car, leaving the rear wheels in their existing alignment. This is common when the rear suspension is non-adjustable or when the rear alignment is within spec; for the best overall handling and tire wear, a full four-wheel alignment is recommended if the rear is adjustable or out of specification.
Understanding two-wheel alignment
A two-wheel alignment focuses on aligning the front wheels relative to each other and to the vehicle’s reference geometry. It typically adjusts toe and, on some vehicles, camber and caster. The rear wheels are not adjusted during a two-wheel alignment. This approach is common on cars with non-adjustable rear suspension or when the rear alignment is already within manufacturer tolerances.
Before listing the scenarios where a two-wheel alignment is appropriate, it’s important to note that not all vehicles allow rear toe or camber adjustments, and some require specialized equipment for accurate measurements. The following points outline typical conditions under which a two-wheel alignment makes sense.
- Rear suspension is non-adjustable (for example, a solid rear axle or leaf springs) and cannot be tuned.
- Rear wheels are within specification and show no abnormal wear or pulling tendencies.
- The driver reports a steering offset or pull that is primarily corrected with front toe adjustments.
- A shop offers a front-end (two-wheel) alignment option to reduce cost or turnaround time when full alignment isn’t necessary.
Concluding: When these conditions apply, a two-wheel alignment can restore proper front-end geometry without touching the rear alignment.
Four-wheel alignment: when a full alignment is needed
Four-wheel alignment adjusts both the front and rear wheels to manufacturer targets, when possible. It provides more comprehensive correction for handling, steering wheel centering, and tire wear, especially on vehicles with adjustable rear suspension or independent rear axles.
Vehicle types and suspension notes
Many modern cars with independent rear suspensions or adjustable rear toe/camber benefit from a full alignment. Vehicles with solid rear axles or non-adjustable rear suspensions may still require only front alignment unless rear wear or handling issues indicate a rear correction is needed.
Before listing the practical scenarios where a four-wheel alignment is advantageous, consider that this method generally requires more time and is often more expensive than a front-only alignment. The points below summarize common situations where a full alignment is recommended.
- Rear toe, camber, or caster are adjustable or out of spec and can affect handling and tire wear.
- Vehicle has independent rear suspension or an adjustable rear alignment setup.
- You notice rear tire wear patterns, poor straight-line stability, or the steering wheel remains off-center after a front-only alignment.
- Aiming for optimal handling and even tire wear across all four tires is a priority for the vehicle’s use (e.g., performance driving, touring, or high-mileage fleets).
Concluding: A full four-wheel alignment is usually the best choice when rear alignment is adjustable or out of spec, or when precise handling and even tire wear are priorities.
How to decide what your vehicle needs
These practical steps help determine whether you should request a two-wheel or four-wheel alignment from a service shop. Start with your vehicle’s symptoms and go from there.
- Inspect tire wear: if wear is heavier on the front tires and the rear tires appear relatively even, a front-end (two-wheel) alignment may suffice.
- Note steering behavior: a consistent pull or off-center steering often points to front toe issues; misalignment at the rear can contribute but is harder to assess without a full measurement.
- Ask the shop to measure rear alignment: if rear toe or camber is out of spec or adjustable, request a four-wheel alignment.
- Consider your vehicle type and suspension: vehicles with non-adjustable rear suspensions typically require only a front alignment unless rear wear is evident or steering issues persist.
Conclusion: A professional inspection with accurate measurements will determine whether a two-wheel or four-wheel alignment is appropriate for your vehicle and driving needs.
Summary
In short, you can align just two wheels in many cases—typically the front wheels on cars with non-adjustable rear suspensions. However, for optimal handling, tire wear, and long-term stability, a full four-wheel alignment is advisable when the rear is adjustable or out of spec. Always consult a qualified technician who can assess your vehicle’s suspension design and measurement data to recommend the right approach.
Can I just get a 2 wheel alignment?
While most modern cars do require a four-wheel alignment, there are a few exceptions. It's impossible to adjust the rear suspension of vehicles with a solid, fixed rear axle — often large trucks, SUVs, classic cars, or cars made by specific manufacturers.
How long does it take to do a 2 wheel alignment?
A two-wheel alignment typically takes 30 to 60 minutes. However, the time can vary depending on factors like the vehicle's condition, suspension complexity, and whether any additional repairs are needed.
Factors that can affect the total time
- Vehicle condition: If suspension or steering components are rusted, damaged, or worn, the mechanic will need to repair or replace them first, which will increase the time required.
- Vehicle type: Sportier cars or high-end vehicles with more complex suspension systems may take longer.
- Type of alignment: A two-wheel alignment is generally faster than a four-wheel alignment, which can take up to two hours.
- Additional repairs: If the technician discovers issues beyond the alignment, such as worn-out parts, the total service time will be longer.
How much does a 2 wheel alignment cost?
A front-end alignment (or two wheel alignment), which involves only the front two wheels, typically costs anywhere from $50 to $75. While a four wheel alignment costs more, usually $100 to $168.
Do you need 2 or 4 wheel alignment?
A four-wheel alignment adjusts both front and rear wheels and is required for most modern vehicles, including front-wheel and all-wheel drive cars, SUVs, and crossovers. A two-wheel alignment (also called a front-end alignment) only adjusts the front wheels and is suitable for vehicles with a fixed rear axle, like some large trucks and classic cars. The main difference is that a four-wheel alignment corrects the alignment of all four wheels, while a two-wheel alignment only addresses the front two.

Two-wheel (front-end) alignment
- What it is: Adjusts the front wheels only.
- What it adjusts: Front suspension and steering angles, including camber, caster, and toe.
- Best for: Vehicles with a solid, non-adjustable rear axle, such as some large trucks, classic cars, and certain manufacturer-specific models.
Four-wheel alignment
- What it is: Adjusts both the front and rear wheels.
- What it adjusts: Adjusts front and rear suspension and steering angles.
- Best for: The vast majority of modern vehicles, including most front-wheel drive, all-wheel drive, small SUVs, and crossovers.
Which one do you need?
- Check your vehicle type: If you drive a modern car, SUV, or crossover, you most likely need a four-wheel alignment.
- Consider the rear axle: If your vehicle has a solid or fixed rear axle, it may only need a two-wheel alignment.
- A four-wheel alignment is often recommended for AWD and 4WD vehicles, as a small misalignment in the rear can affect the entire drivetrain and handling.
