🔧 Strut Replacement - Front Suspension Repair

This job replaces the front strut assemblies on your S60. The strut carries the spring and damper, so you’ll be removing a loaded suspension component and transferring or replacing the spring hardware if you are not using a complete pre-assembled strut.

Difficulty Level: Advanced | Estimated Time: 4-6 hours

⚠️ Safety & Precautions

• Front struts are under heavy spring tension. Use a spring compressor (specialty) if the new strut is not pre-assembled.
• Support the vehicle with jack stands. Never work under a car supported only by a jack.
• Disconnect the negative battery cable if you must unplug any suspension sensors near the strut area.
• Do not let the brake hose or ABS wire hang from the knuckle.
• After replacement, an alignment is required.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Loosen the front wheel lug nuts before lifting the car.
• If your struts are being replaced with complete assemblies, skip spring compression.
• Mark the position of the strut to knuckle relationship before removal. Helps keep alignment close.

🔨 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 S60 at the approved jacking point.
• Place jack stands under the proper support points and lower the vehicle onto them.
• Remove both front wheels with the ratchet and 21mm socket.

Step 2: Free the strut from attached components

• Use the 13mm socket or 15mm socket to remove the brake hose bracket and any wire clips from the strut body.
• Use the Torx bit set if the ABS wire bracket uses Torx fasteners.
• Disconnect the stabilizer link from the strut if it blocks removal. Use the 15mm wrench and ball joint separator if needed.

Step 3: Mark and separate the strut from the knuckle

• Use a paint marker to mark the strut-to-knuckle position.
• Use the 18mm socket and breaker bar to remove the lower strut bolts.
• Support the knuckle with one hand so the axle and brake hose are not stressed.
• Slide the knuckle down and away from the strut.

Step 4: Remove the upper strut mount nuts

• Open the hood.
• Use the 13mm socket or 15mm socket to remove the upper mount nuts.
• Hold the strut with your other hand so it does not drop out.
• Remove the strut assembly from the wheel well.

Step 5: Transfer the spring hardware or install the complete assembly

• If you bought a complete strut assembly, install it now and skip spring compression.
• If reusing the spring, use the spring compressor to compress the coil spring evenly.
• Remove the top nut and transfer the spring, mount, bearing, boot, and bump stop to the new strut.
• Make sure the spring ends sit in the correct pockets. Mis-seated springs cause clunks.

Step 6: Install the new strut

• Guide the strut into the tower and start the upper mount nuts by hand with the 13mm socket.
• Align the bottom of the strut with the knuckle using your paint marks as a guide.
• Install the lower strut bolts with the 18mm socket.
• Reattach the stabilizer link using the 15mm wrench.

Step 7: Reinstall brackets and tighten fasteners

• Reinstall the brake hose bracket and ABS wire clips with the 13mm socket or Torx bit set.
• Torque the upper strut mount nuts to factory specification.
• Torque the lower strut-to-knuckle bolts to factory specification.
• Torque the stabilizer link fasteners to factory specification.

Step 8: Reinstall wheels and lower the vehicle

• Install the wheels and snug the lug nuts with the 21mm socket.
• Lower the car to the ground with the floor jack.
• Torque the lug nuts to factory specification.

✅ After Repair

• Test drive slowly and listen for clunks or rattles.
• Check the brake hose and ABS wire routing after the first drive.
• Schedule a 4-wheel alignment right away.
• If you replaced one side only, the car may sit unevenly until both sides settle.
