🔧 Yaris - Front Strut Replacement

Assumption: This guide covers the front struts on your Yaris hatchback. Front struts affect ride control and alignment, so both sides should be replaced together.

The front suspension strut is a loaded part, so it must be handled carefully during removal and installation. After replacement, a wheel alignment is required to protect tires and keep the car driving straight.

Difficulty Level: Intermediate | Estimated Time: 3-5 hours

⚠️ Safety & Precautions

• Use a spring compressor only if you are transferring the coil spring and top mount to the new strut. A compressed coil spring stores a lot of energy and can cause serious injury.
• Support the car securely with jack stands before removing any suspension parts.
• Do not let the brake hose or ABS wire hang by its own weight.
• Keep the steering knuckle supported when the strut is removed.
• Disconnect the battery only if you need to move the steering wheel or unplug related sensors.
• Finish with a professional wheel alignment.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the car

• Use the floor jack to lift the front of the Yaris at the approved lift point.
• Place jack stands under the front support points and lower the car onto them.
• Remove both front wheels with the 21mm lug wrench or socket.

Step 2: Free the strut from attached components

• Use the 10mm socket or 12mm socket to remove any brake hose or ABS wire brackets attached to the strut.
• Use the 17mm socket and a matching wrench to remove the stabilizer link nut from the strut.
• Spray rusty fasteners early.

Step 3: Mark the strut position

• Use a paint marker to mark the strut-to-knuckle relationship.
• This helps keep the knuckle close to its original position before alignment.

Step 4: Remove the strut from the knuckle

• Use the 19mm socket and breaker bar to remove the lower strut-to-knuckle bolts and nuts.
• Support the steering knuckle so the axle and brake hose are not strained.
• Separate the strut from the knuckle and move it clear of the wheel well.

Step 5: Remove the upper strut mount nuts

• Open the hood and locate the top strut mount.
• Use the 14mm socket to remove the upper mounting nuts.
• Hold the strut assembly with your other hand so it does not drop.

Step 6: Transfer parts if needed

• If your replacement is a complete strut assembly, skip this step.
• If reusing the spring, install the spring compressor (specialty) on the old strut spring and compress it evenly.
• Use the socket set and a matching wrench to remove the top shaft nut and disassemble the strut.
• Transfer the spring, mount, bearing, bumper, and boot to the new strut.
• Keep the spring hooks fully seated.

Step 7: Install the new strut

• Position the new strut in the tower and start the upper nuts by hand using the 14mm socket.
• Align the lower strut bracket with the steering knuckle.
• Install the lower bolts and nuts using the 19mm socket.
• Torque to 175 Nm (129 ft-lbs) for the lower strut-to-knuckle bolts.

Step 8: Reconnect brackets and stabilizer link

• Use the 10mm socket or 12mm socket to reinstall the brake hose and ABS wire brackets.
• Use the 17mm socket and wrench to reinstall the stabilizer link nut.
• Torque to 49 Nm (36 ft-lbs) for the stabilizer link nut.

Step 9: Tighten the upper mount and reinstall wheels

• Use the 14mm socket to torque the upper strut mount nuts.
• Torque to 52 Nm (38 ft-lbs) for the upper mount nuts.
• Reinstall the wheels with the 21mm lug wrench or socket.
• Torque to 103 Nm (76 ft-lbs) for the lug nuts.

✅ After Repair

• Check that all fasteners are tight and all hoses/wires are clipped back into place.
• Start the car and turn the steering wheel lock-to-lock while parked to check for binding or odd noises.
• Road test slowly first, then listen for clunks or rattles.
• Get a professional front-end alignment as soon as possible.
• Recheck lug nut torque after 50-100 miles.
