🔧 Fusion - Front Strut Replacement

On your Fusion, the front suspension uses MacPherson struts (the strut is the shock absorber plus the spring). Replacing worn struts restores ride control, braking stability, and tire wear.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

Assumption: This covers FRONT struts; the rear uses shocks (not struts).

⚠️ Safety & Precautions

• ⚠️ Use jack stands under the pinch welds or front subframe; never rely on a floor jack alone.
• ⚠️ If you are not installing “quick struts,” you must compress the coil spring—coil springs store dangerous energy.
• ⚠️ Keep clear of orange high-voltage hybrid cables; do not pry on, pull, or drill near them.
• ⚠️ Support the steering knuckle so the axle and brake hose are not stretched.
• ⚠️ After strut replacement, a 4-wheel alignment is required to prevent tire wear.

📋 Before You Begin

• 🅿️ Park on level ground, steering wheel straight, and chock the rear wheels.
• 🧰 If you’re not using “quick struts”: a spring compressor is a clamp tool that safely squeezes the coil spring so the top mount can be removed.
• 🧼 Spray penetrating oil on the strut-to-knuckle bolts and sway bar end link nuts 10–15 minutes before disassembly.
• 🖊️ Use a paint marker to mark the strut-to-knuckle position to help keep alignment close enough to drive to an alignment shop.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and raise the front

• Use a 21mm lug nut socket and breaker bar to loosen the front lug nuts 1/2 turn (do not remove yet).
• Use a floor jack (rated 3-ton minimum) to lift the front of the car.
• Set the car onto jack stands (rated 3-ton minimum) and confirm it is stable.
• Remove the wheels using the 21mm lug nut socket.

Step 2: Unbolt hose/wire brackets from the strut

• Use a socket set (10mm–24mm, 1/2" drive) (commonly 10mm) to remove the brake hose/ABS wire brackets from the strut body.
• Use a trim clip tool and needle-nose pliers to release any clips holding the wiring to the strut.
• Tip: Don’t let the caliper hose hang or twist.

Step 3: Disconnect the sway bar end link from the strut

• Use a wrench set (10mm–24mm) and socket set (10mm–24mm, 1/2" drive) to remove the sway bar end link nut at the strut bracket.
• If the stud spins, hold it with the appropriate internal hex/Torx using your socket set while turning the nut with a wrench set.

Step 4: Support the steering knuckle

• Place a floor jack (rated 3-ton minimum) lightly under the lower control arm/knuckle area to support the assembly.
• This prevents the axle and brake hose from being pulled when the strut comes loose.

Step 5: Remove the strut-to-knuckle bolts

• Mark the bolt/knuckle relationship using a paint marker.
• Use a breaker bar (1/2") with your socket set (10mm–24mm, 1/2" drive) and a matching wrench set (10mm–24mm) to remove the two strut-to-knuckle bolts and nuts.
• If the bolts are stuck, use penetrating oil, then tap them out using a hammer (2–3 lb) and punch (6–8mm).

Step 6: Remove the upper strut mount nuts

• Open the hood.
• Use a socket set (10mm–24mm, 1/2" drive) to remove the upper strut mount nuts (typically three).
• Keep one nut threaded a few turns until you’re ready to catch the strut.
• Support the strut with one hand and remove the last nut using the socket set, then lift the strut out.

Step 7: If NOT using quick struts, transfer the spring and mount

• Install a spring compressor (specialty) on the coil spring and compress evenly until the spring is loose in the mount.
• Remove the top nut using a socket set (10mm–24mm, 1/2" drive) while holding the strut shaft as needed with your wrench set (10mm–24mm).
• Transfer the mount/bearing and spring to the new strut in the same orientation.
• Slowly release the spring compressor (specialty), making sure the spring seats correctly in the upper and lower pockets.
• Tip: If you’re unsure, buy quick struts.

Step 8: Install the new strut into the tower

• Position the strut up into the strut tower.
• Hand-start the upper mount nuts, then snug them with a socket set (10mm–24mm, 1/2" drive).
• Torque to 46 Nm (34 ft-lbs) for the upper mount nuts.

Step 9: Attach strut to steering knuckle

• Align the strut to the knuckle using your paint marks.
• Install the strut-to-knuckle bolts using the socket set (10mm–24mm, 1/2" drive) and wrench set (10mm–24mm).
• Torque to 175 Nm (129 ft-lbs) for the strut-to-knuckle bolts.

Step 10: Reconnect sway bar end link and brackets

• Reconnect the sway bar end link to the strut bracket using a socket set (10mm–24mm, 1/2" drive) and wrench set (10mm–24mm).
• Torque to 85 Nm (63 ft-lbs) for the sway bar end link nut.
• Reinstall brake hose/ABS brackets using the socket set (10mm–24mm, 1/2" drive).
• Torque to 10 Nm (89 in-lbs) for small bracket bolts.

Step 11: Reinstall wheels and lower the car

• Reinstall the wheels and hand-thread lug nuts.
• Lower the car using the floor jack (rated 3-ton minimum).
• Use a torque wrench (20–250 ft-lbs range) and 21mm lug nut socket to torque lug nuts in a star pattern: Torque to 135 Nm (100 ft-lbs).

✅ After Repair

• 🧪 Road test at low speed first; listen for clunks over bumps and confirm steering returns to center.
• 🔍 Recheck that ABS wiring and brake hoses are clipped and not rubbing the tire.
• 🛞 Get a professional 4-wheel alignment as soon as possible.
• 🧰 After 50–100 miles, recheck lug nut torque with a torque wrench: Torque to 135 Nm (100 ft-lbs).
