Step-by-Step Procedure for Removing the Old Strut Assembly
Removing the strut assembly from a Subaru Crosstrek involves several careful steps to avoid damage to suspension components and ensure proper reinstallation:
First, ensure the vehicle is parked on a level surface, and the parking brake is engaged. Loosen the lug nuts on the wheel where the strut will be replaced but do not remove them yet. Using the jack, lift the vehicle and securely place it on jack stands. Remove the wheel to expose the strut assembly.
Next, spray penetrating oil on the strut mounting bolts and nuts to ease removal. Locate the brake line and ABS sensor wire attached to the strut; carefully unclip or remove their fasteners to prevent damage.
Proceed to loosen and remove the bolts securing the strut to the steering knuckle at the lower end. These bolts may require a breaker bar for extra leverage. Once free, support the steering knuckle to prevent strain on brake lines.
Under the hood, open the strut tower cover to access the upper strut mounting nuts. Remove the nuts while holding the strut shaft steady to prevent it from spinning. Once the upper mount is free, carefully lower and remove the entire strut assembly from the vehicle.
Throughout removal, take care not to damage the coil spring or other suspension parts. Use caution when handling the strut assembly, as the coil spring is under tension.
Installing the New Strut Assembly
Installing the replacement strut assembly on a Subaru Crosstrek requires attention to alignment and torque specifications to maintain suspension performance:
Start by compressing the new strut’s coil spring using a spring compressor tool, following all safety guidelines to avoid accidents. Once compressed, assemble any necessary components onto the strut, such as the mount or dust boot, if not pre-installed.
Position the new strut assembly into the strut tower and loosely thread the upper mounting nuts by hand to hold it in place. Next, align the lower strut end with the steering knuckle and insert the mounting bolts.
Hand-tighten all bolts initially, then use a torque wrench to tighten the upper mounting nuts and lower bolts to the manufacturer’s specified torque values. Applying anti-seize lubricant to bolt threads during installation is recommended to prevent future corrosion and facilitate easier removal.
Reattach the brake line and ABS sensor wire brackets to the new strut assembly. Double-check that all clips and fasteners are secure.
After the strut is fully installed, reinstall the wheel, hand-tighten the lug nuts, lower the vehicle from the jack stands, and then torque the lug nuts to the specified value.
| Component | Torque Specification | Notes |
|---|---|---|
| Upper strut mounting nuts | 37-44 ft-lbs (50-60 Nm) | Hold strut shaft steady while tightening |
| Lower strut to steering knuckle bolts | 59-74 ft-lbs (80-100 Nm) | Use anti-seize on threads |
| Wheel lug nuts | 80-90 ft-lbs (108-122 Nm) | Torque with vehicle on ground |
Post-Installation Checks and Considerations
After completing the strut replacement, several checks and adjustments are important to ensure optimal vehicle performance and safety.
Visually inspect the installation area for any loose bolts or components. Confirm that brake lines and ABS sensor wires are properly routed and secured without tension or risk of rubbing.
It is highly recommended to have a professional alignment performed. Replacing struts often alters suspension geometry, and proper wheel alignment is crucial to prevent uneven tire wear and maintain handling characteristics.
Test drive the vehicle at low speeds to listen for unusual noises such as clunks or rattles, which may indicate loose components. Pay attention to ride quality and steering response.
Regularly check the strut mounts and fasteners during early use to confirm they remain tight and intact. Monitor tire wear patterns over the coming weeks for any signs of misalignment.
