Do I need an alignment after replacing struts?
Yes. In most cases you should plan for a wheel alignment after replacing struts to ensure proper steering, handling, and even tire wear.
Why strut replacement can impact alignment
Struts are part of the suspension geometry. Replacing them involves removing and reinstalling components, which can alter ride height, mounting angles, and the way the wheel sits in relation to the body. Even if you replace only the dampers, the process can disturb alignment settings or allow the suspension to settle differently after the install. Because of this, a wheel alignment is commonly recommended, especially on the front axle where toe and camber influence handling most noticeably.
Adjustability and vehicle design
Not all struts are adjustable. Some vehicles use fixed strut mounts with no camber or toe adjustability, while others include adjustable control arms or strut mounts that can tweak camber. Even on non-adjustable systems, alignment can shift due to ride-height changes, sagging springs, or wear on related components such as tie rods and control arms. If the service disturbed mounting hardware or altered ride height, an alignment is advisable.
Before you proceed with any service, or if you recently replaced struts yourself, you should be aware that alignment needs can vary by vehicle and by the extent of the work performed.
When you take the car in for service, or after a DIY strut replacement, it’s common to expect that alignment may be addressed as part of the repair process. Below is a guide to what typically happens and how to plan.
What to expect from an alignment after strut replacement
- 4-wheel alignment is often recommended; front-end alignment alone may be insufficient on newer cars with sensitive toe or caster settings.
- Camber, toe, and sometimes caster are checked and adjusted using the vehicle's alignment rack and adjustable components (tie rods, control arms, or adjustable strut mounts).
- Technicians typically perform a drive test and may re-check alignment after a short road test to confirm stability.
- Some cars require alignment after strut work even if the parts replaced were identical to the original.
Having an alignment after strut replacement helps ensure even tire wear, predictable steering, and safe vehicle handling.
What you can do to prepare and improve results
Preparing for alignment after strut replacement can help ensure the job is done right the first time and may reduce the need for a recheck or retightening later.
How to plan and what to expect during the service
- Have the suspension components on both sides inspected for wear; replace worn bushings, ball joints, or tie rods as needed.
- Ask for a full 4-wheel alignment if possible, not just the front wheels.
- Bring the vehicle with the same tires and tire pressures that will be used during alignment; otherwise the results can vary.
- Drive the vehicle for a short distance (the shop may advise) to allow struts to settle before final alignment adjustment.
A brief post-install alignment check, followed by a road test, helps confirm proper tracking and tire wear patterns.
When you might skip a full alignment
In some cases, if the strut replacement involved only the dampers and nothing else in the suspension was disturbed, and the ride height remains unchanged, you may be able to postpone a full alignment. However, you should still have the vehicle inspected for tire wear and steering behavior, and be prepared for a check if you notice pulling, uneven tire wear, or a wandering steering feel.
Summary
Replacing struts can alter suspension geometry and ride height, which often makes an alignment necessary or highly advisable. Even if the parts replaced are identical and non-adjustable, many vehicles benefit from a full 4-wheel alignment after service. If you notice pulling, vague steering, or unusual tire wear after replacement, don’t delay—have the alignment checked by a qualified technician. Regular maintenance and suspension inspections help maintain safe handling and tire longevity.
