Yes, you should get a wheel alignment after replacing struts in most cases

Struts are part of your vehicle's suspension system — they hold the wheel in place and absorb bumps from the road. When you replace them, the angle at which your wheels sit relative to the ground often shifts, even slightly. A wheel alignment is a service that adjusts those angles back to the manufacturer's specification. Without it, your tires wear unevenly, your steering may feel off-center, and your fuel economy can drop.

Whether alignment is strictly necessary depends on what you replaced and how carefully the work was done. If you replaced only the strut cartridge (the internal part) and the strut housing stayed in place, alignment may not shift much. If you replaced the entire strut assembly or worked on both front struts, misalignment is more likely. A technician can check your alignment before and after the job to tell you whether it has moved enough to matter.

The cost of alignment typically ranges from $100 to $300 depending on your vehicle and whether it is a two-wheel or four-wheel alignment. That is usually less than the cost of replacing tires prematurely due to uneven wear, so most shops recommend it as a matter of routine.

Key Takeaways

  • Replacing struts can shift the angle of your wheels, which causes uneven tire wear and steering problems if not corrected.
  • A wheel alignment after strut replacement costs between $100 and $300 and typically takes 30 minutes to an hour.
  • If you replaced only the strut cartridge and the strut housing did not move, alignment may not shift enough to require correction.
  • Many shops include a post-replacement alignment check in their service, so ask whether your repair estimate covers this step.
  • Skipping alignment after strut replacement often leads to tire replacement sooner than expected, making alignment the cheaper option upfront.

How strut replacement affects wheel angles

Your wheels sit at three key angles: camber (tilt inward or outward), caster (tilt forward or backward), and toe (point inward or outward). The strut assembly holds the wheel in place and determines these angles. When you remove and reinstall a strut, even small differences in how the bolts are torqued or how the assembly seats can shift these angles.

The front struts have the most impact on alignment because they carry more of the vehicle's weight and steer the direction of travel. Rear struts affect alignment too, but the effect is usually less noticeable to the driver. If your shop replaced both front struts, alignment is almost certain to have shifted. If they replaced one strut, the vehicle may pull slightly to one side.

Some shops use alignment racks that measure wheel angles before and after the strut job. This tells you whether the angles have moved enough to warrant correction. If the angles are still within the manufacturer's range, you may not need alignment. If they are outside that range, correction is necessary.

What happens if you skip alignment after strut replacement

The most common result is uneven tire wear. If your camber is off, the inside or outside edge of the tire wears faster than the center. If your toe is off, the tire scrubs sideways as you drive, wearing both edges while the center stays thick. This kind of wear can reduce tire life by 25 to 50 percent, depending on how far out of alignment you are.

You may also notice your steering wheel is off-center — it points slightly left or right even when you are driving straight. This is usually a toe problem. Some drivers compensate by holding the wheel at an angle, which is uncomfortable and makes steering less responsive in an emergency.

Fuel economy can drop by 3 to 5 percent when alignment is poor, because the tires are fighting each other instead of rolling freely. Over the life of a tank, this adds up to real money. The combination of early tire wear, poor handling, and lower fuel economy usually costs more than the alignment service would have.

When alignment is less critical after strut replacement

If your shop replaced only the strut cartridge — the internal shock absorber part — and left the strut housing and mounting points untouched, the wheel angles may not shift at all. The cartridge is a sealed unit inside the housing, and swapping it out does not move the housing itself. In this case, alignment may not be necessary.

Some vehicles have strut cartridges that can be replaced without removing the entire strut assembly from the car. This is called a strut cartridge replacement or strut insert replacement. It is less common than full strut replacement, but when it is done correctly, wheel angles usually stay the same.

Ask your technician whether they replaced the cartridge only or the entire assembly. If they replaced the entire assembly, alignment is the safer choice. If they replaced only the cartridge and did not disturb the mounting points, you can ask them to check alignment before you leave — many shops will do this for free or a small fee.

Two-wheel versus four-wheel alignment after strut replacement

A two-wheel alignment adjusts only the front wheels. This is the standard choice after front strut replacement because the front wheels do the steering and carry most of the vehicle's weight. Two-wheel alignment usually costs $100 to $200.

A four-wheel alignment adjusts all four wheels. This is necessary if you replaced rear struts or if your vehicle has independent rear suspension that can be adjusted. Four-wheel alignment costs more — usually $150 to $300 — but it ensures that your rear wheels are not pulling your front wheels out of line.

If you replaced only front struts, ask your shop whether a two-wheel alignment is sufficient for your vehicle. Some cars with independent rear suspension benefit from four-wheel alignment even after front-only work. Your owner's manual or the shop can tell you which is right for your vehicle.

How to know if alignment has shifted after strut replacement

The most obvious sign is that your steering wheel is off-center. Drive straight on a flat, empty road with your hands off the wheel for a moment (safely). If the car drifts left or right, your toe angle is probably off. If the steering wheel itself is tilted when you are driving straight, that is also a sign of misalignment.

Uneven tire wear is another clue, but it takes weeks or months to become visible. Check your tires a few weeks after the strut replacement. If the inside or outside edge is noticeably more worn than the center, alignment is off. This is easier to spot if you compare the wear on the two front tires — one may be worse than the other if only one strut was replaced.

The best approach is to have the shop check alignment before you leave. Most reputable shops will do this as part of their post-repair inspection. If they do not offer it, ask them to measure your alignment angles and tell you whether they are within spec. This takes 15 to 20 minutes and costs little or nothing.

What to expect during a wheel alignment service

The technician will drive your vehicle onto an alignment rack — a platform with sensors under each wheel. The sensors measure the angle of each wheel relative to the vehicle's frame and the road. This takes about 5 to 10 minutes.

The technician then compares the measured angles to your vehicle's manufacturer specifications. These specs vary by make, model, and year. If any angle is outside the acceptable range, the technician adjusts it by loosening bolts and moving the wheel assembly slightly. Adjustments are made to the tie rods (which control toe) and sometimes to the strut mounting points (which control camber and caster).

The whole process usually takes 30 minutes to an hour. You will receive a printout showing the before and after angles. Keep this for your records — it proves that alignment was corrected and can help if you have a warranty claim on your tires later.

Frequently Asked Questions

Can I drive my car right after strut replacement without alignment?

Yes, you can drive it, but you should not drive it long distances or at highway speeds until alignment is checked. Short trips to the alignment shop are fine. Driving for weeks or months without alignment will cause uneven tire wear that becomes expensive to fix.

Does the shop that replaced my struts have to do the alignment?

No, but most shops offer it as an add-on service. You can take your vehicle to a different shop for alignment if you prefer. Some independent alignment shops charge less than dealerships. Get a quote from your strut shop first, then compare.

How long does alignment last after strut replacement?

A proper alignment should last until your next major suspension work or until you hit a large pothole or curb hard enough to shift the wheels again. Most alignments do not need to be redone unless something damages the suspension.

Will my warranty cover alignment if the struts were replaced under warranty?

That depends on the warranty terms. Some warranties cover alignment as part of the repair; others do not. Ask the shop or manufacturer before you authorize the strut replacement. If alignment is not covered, ask for a discount on the alignment service since it is a direct result of the warranty repair.

What if my alignment is still off after the service?

Reputable shops may provide their alignment work for a set period — usually 30 to 90 days. If your steering wheel is still off-center or your tires are still wearing unevenly within that window, take the vehicle back and ask them to re-check and re-adjust for free. Get the may provide terms in writing before you pay.
