⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground only.
• ⚠️ Always support your Outback with jack stands. Never rely on a floor jack alone.
• ⚠️ Do not loosen the center nut on the strut shaft unless the coil spring is safely compressed. The spring is under extreme force.
• ⚠️ Complete strut assemblies are safer for beginners because the spring is already installed.
• ⚠️ An alignment is required after this repair because the strut affects wheel angle.
• ⚠️ Battery disconnect is not required for this repair.

📋 Before You Begin

• Park your Outback on level ground and set the parking brake.
• Place wheel chocks behind the rear wheels. Wheel chocks are wedges that stop the vehicle from rolling.
• Loosen the front lug nuts slightly before lifting the vehicle.
• Spray penetrating oil on the lower strut bolts and sway bar link nuts. Let it soak for 10-15 minutes.
• Use complete strut assemblies for a beginner-friendly repair. This avoids dangerous spring compression.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use a 19mm socket and 1/2-inch drive breaker bar to loosen each front lug nut about half a turn.
• Do not remove the lug nuts yet.
• Tip: Break them loose before lifting.

Step 2: Raise and Support the Front of the Vehicle

• Use a floor jack rated 2-ton minimum to lift the front of your Outback at the front center jacking point.
• Place jack stands rated 2-ton minimum under the front side pinch welds or approved support points.
• Lower the vehicle gently onto the jack stands.
• Keep the floor jack lightly touching as a backup only.

Step 3: Remove the Front Wheels

• Use a 19mm socket and 1/2-inch drive ratchet to remove the loosened lug nuts.
• Remove both front wheels and set them flat under the vehicle as an extra safety backup.

Step 4: Mark the Strut-to-Knuckle Position

• Use a paint marker to mark the position of the lower strut bracket against the steering knuckle.
• The steering knuckle is the large metal part behind the wheel hub that turns when you steer.
• This mark helps keep the alignment close enough to drive to an alignment shop.

Step 5: Remove the Brake Hose and ABS Wire Brackets

• Use a 12mm socket and 3/8-inch drive ratchet to remove the brake hose bracket bolt from the strut.
• Use a 12mm socket and 3/8-inch drive ratchet to remove the ABS wheel speed sensor wire bracket from the strut if equipped.
• Use a flathead screwdriver or needle-nose pliers to gently release any plastic wire clips.
• Do not let the brake hose hang tight or stretch.

Step 6: Disconnect the Stabilizer Link from the Strut

• Use a 17mm socket and 1/2-inch drive ratchet to remove the stabilizer link nut from the strut bracket.
• If the stud spins, hold the stud with the correct internal hex or gripping area if present, then remove the nut with a 17mm wrench.
• The stabilizer link connects the sway bar to the strut and helps reduce body roll in turns.
• Move the link aside after the nut is removed.

Step 7: Support the Steering Knuckle

• Use the floor jack rated 2-ton minimum under the lower control arm or outer knuckle area with light upward pressure.
• This prevents the brake hose and axle from being pulled downward when the strut bolts are removed.
• Do not lift the vehicle off the jack stands.

Step 8: Remove the Lower Strut Bolts

• Use a 19mm socket, 19mm wrench, and 1/2-inch drive breaker bar to loosen the two large strut-to-knuckle nuts and bolts.
• Remove the lower bolt first, then the upper bolt.
• Use a rubber mallet to tap stubborn bolts out gently.
• Do not use a steel hammer directly on the bolt threads.

Step 9: Remove the Upper Strut Mount Nuts

• Open the hood.
• Use a 14mm socket and 3/8-inch drive ratchet to remove the three upper strut mount nuts from the strut tower.
• Hold the strut with one hand while removing the last nut so it does not fall.
• Do not remove or loosen the center strut shaft nut.

Step 10: Remove the Old Strut Assembly

• Lower the complete strut assembly out through the wheel well by hand.
• Use mechanic gloves because the strut edges and brackets can be sharp.
• Compare the old and new strut assemblies before installation.
• Make sure the brake hose bracket, sway bar link bracket, and upper mount orientation match.

Step 11: Install the New Strut Assembly

• Guide the new complete strut assembly up into the strut tower by hand.
• Install the three upper mount nuts by hand first to prevent cross-threading.
• Use a 14mm socket and torque wrench rated to 150 ft-lbs to tighten the upper strut mount nuts to Torque to 20 Nm (15 ft-lbs).

Step 12: Reconnect the Strut to the Steering Knuckle

• Align the lower strut bracket with the steering knuckle using your paint marks as a guide.
• Use the floor jack rated 2-ton minimum to raise or lower the knuckle slightly until the bolt holes line up.
• Insert the upper and lower strut-to-knuckle bolts by hand.
• Install the nuts by hand.
• Use a 19mm socket, 19mm wrench, and torque wrench rated to 150 ft-lbs to tighten the strut-to-knuckle nuts to Torque to 155 Nm (114 ft-lbs).

Step 13: Reconnect the Stabilizer Link

• Insert the stabilizer link stud into the strut bracket.
• Install a new stabilizer link nut by hand.
• Use a 17mm socket, 17mm wrench, and torque wrench rated to 150 ft-lbs to tighten the nut to Torque to 45 Nm (33 ft-lbs).

Step 14: Reattach Brake Hose and ABS Wire Brackets

• Use a 12mm socket and 3/8-inch drive ratchet to reinstall the brake hose bracket bolt.
• Use a torque wrench rated to 150 ft-lbs with the 12mm socket to tighten the bracket bolt to Torque to 18 Nm (13 ft-lbs).
• Use a 12mm socket and 3/8-inch drive ratchet to reinstall the ABS wire bracket bolt if equipped.
• Use a torque wrench rated to 150 ft-lbs with the 12mm socket to tighten the ABS bracket bolt to Torque to 18 Nm (13 ft-lbs).
• Make sure the brake hose and ABS wire are not twisted, stretched, or rubbing the tire.

Step 15: Repeat on the Other Side

• Repeat Steps 4 through 14 on the opposite front strut.
• Always replace front struts in pairs so the suspension feels balanced.

Step 16: Reinstall the Front Wheels

• Place each wheel back onto the hub.
• Install the lug nuts by hand first.
• Use a 19mm socket and 1/2-inch drive ratchet to snug the lug nuts in a star pattern.

Step 17: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack rated 2-ton minimum to lift the vehicle slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower your Outback fully to the ground.
• Use a 19mm socket and torque wrench rated to 150 ft-lbs to tighten the wheel lug nuts in a star pattern to Torque to 120 Nm (89 ft-lbs).

✅ After Repair

• ✅ Turn the steering wheel fully left and right while parked. Listen for rubbing, clunks, or pulling wires.
• ✅ Test drive slowly at first. Listen for knocking or looseness over small bumps.
• ✅ Get a professional four-wheel alignment as soon as possible.
• ✅ Recheck lug nut torque after 50-100 miles.
• ✅ If the steering wheel is off-center or the vehicle pulls, avoid highway driving until aligned.
