Do you need an alignment after replacing struts Subaru?
Yes, you typically need to have your vehicle's alignment checked and adjusted after replacing the struts on a Subaru. Replacing the struts can affect the vehicle's suspension geometry, which can lead to improper wheel alignment and cause issues with handling, tire wear, and overall driving performance.
Why Alignment is Necessary After Strut Replacement
The struts on a Subaru are a critical component of the vehicle's suspension system. They provide both shock absorption and structural support for the wheels and tires. When the struts are replaced, it can change the suspension geometry, including the camber, caster, and toe angles of the wheels. These alignment angles need to be within the manufacturer's specified tolerances to ensure proper handling, tire wear, and overall vehicle safety.
If the alignment is not checked and adjusted after strut replacement, the vehicle may exhibit the following issues:
- Uneven or premature tire wear - Improper alignment can cause the tires to wear unevenly, leading to the need for early replacement.
- Pulling or drifting - The vehicle may pull to one side or the other while driving, making it difficult to keep the car centered in the lane.
- Unstable handling - Misaligned wheels can cause the vehicle to feel unstable or "wandering" at highway speeds.
- Increased fuel consumption - Misaligned wheels create additional rolling resistance, which can reduce fuel efficiency.
To ensure your Subaru is driving safely and efficiently after strut replacement, it's highly recommended to have a professional alignment performed.
The Alignment Process
During a wheel alignment, a technician will use specialized equipment to measure the camber, caster, and toe angles of each wheel. They will then make adjustments to the suspension components to bring these angles back within the manufacturer's specifications. This typically involves adjusting the tie rods, control arms, and other suspension linkages.
The entire alignment process usually takes 30-60 minutes, depending on the complexity of the vehicle and any additional repairs that may be needed. It's a good idea to have the alignment checked periodically, even if you haven't replaced any suspension components, to ensure your Subaru is driving at its best.
