🔧 Altima - Front Strut Replacement

On your Altima, the front suspension uses MacPherson struts (strut + spring together). Replacing worn struts restores ride control, braking stability, and reduces clunking/bouncing.

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

⚠️ Safety & Precautions

• ⚠️ The coil spring is under high force—if you are not using complete “quick strut” assemblies, use a proper spring compressor and keep hands/face away from the spring path.
• ⚠️ Support the steering knuckle so it doesn’t pull on the axle/CV joint or brake hose when the strut is removed.
• ⚠️ Always use jack stands; never work under a car supported only by a floor jack.
• ⚠️ After strut replacement, you should get a front wheel alignment to prevent tire wear and pulling.
• Disconnecting the battery is not required for this job.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Spray penetrating oil on the strut-to-knuckle bolts/nuts and sway bar end link nut 10–15 minutes before removal.
• If you are not using quick struts: a “spring compressor” clamps the coil spring so you can safely remove the top nut—inspect the tool carefully before use.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the wheel lug nuts and raise the front

• Use a 21mm socket and breaker bar to loosen (do not remove) the front lug nuts.
• Use a floor jack to lift the front jacking point, then set the car securely on jack stands.
• Remove the wheels with a 21mm socket.
• Reinstall later: Torque to 113 Nm (83 ft-lbs).

Step 2: Unbolt brackets from the strut body

• Use a 12mm socket to remove the brake hose/ABS wire brackets from the strut (if equipped).
• Don’t let hoses hang by tension.

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

• Use a 14mm wrench on the nut while holding the stud with the correct hex key (if the stud spins).
• Move the end link aside.
• Reinstall later: Torque to 65 Nm (48 ft-lbs).

Step 4: Mark camber position (if applicable) and support the knuckle

• Use a paint marker to mark the strut-to-knuckle bolt positions so you can reassemble close to the original alignment.
• Use a floor jack to lightly support the steering knuckle/lower control arm area.

Step 5: Remove the strut-to-knuckle bolts

• Use 19mm/21mm sockets (and matching wrenches) with a breaker bar to remove the two large bolts/nuts holding the strut to the steering knuckle.
• If the bolts are stuck, use penetrating oil and tap them out with a hammer.
• Reinstall later: Torque to 125 Nm (92 ft-lbs).

Step 6: Remove the strut mount nuts at the top

• Open the hood.
• At the strut tower, use a 14mm socket to remove the strut mount nuts (typically 3 nuts).
• Hold the strut so it doesn’t drop, then remove the strut assembly from the wheel well.

Step 7A: If installing quick strut assemblies (recommended path)

• Compare old vs new: spring orientation, mount stud pattern, and overall length.
• Place the new quick strut into the tower and hand-start the top nuts using a 14mm socket.
• Slide the knuckle onto the strut and install the two lower bolts/nuts using 19mm/21mm sockets and wrenches.
• Reconnect the sway bar end link using a 14mm wrench and hex key if needed.

Step 7B: If reusing the spring (spring compressor path)

• Install the spring compressor (specialty) onto opposite sides of the spring and tighten evenly until the spring is loose in the seats.
• Remove the center top nut using a pass-through strut nut socket set (specialty).
• Transfer the spring, isolators, dust boot, bump stop, and mount/bearing as needed onto the new strut.
• Install the top nut with the pass-through strut nut socket set (specialty): Torque to 59 Nm (44 ft-lbs).
• Slowly and evenly release the compressor, ensuring the spring ends sit correctly in the upper/lower seats.

Step 8: Final tighten all fasteners

• Top mount nuts at the tower using a 14mm socket: Torque to 44 Nm (33 ft-lbs).
• Strut-to-knuckle bolts using 19mm/21mm sockets and a torque wrench: Torque to 125 Nm (92 ft-lbs).
• Sway bar end link nut using a 14mm wrench: Torque to 65 Nm (48 ft-lbs).
• Brake hose/ABS brackets using a 12mm socket: Torque to 10 Nm (89 in-lbs).

Step 9: Reinstall wheels and lower the car

• Install the wheels and hand-tighten lug nuts using a 21mm socket.
• Lower the car with the floor jack.
• Tighten lug nuts in a star pattern using a torque wrench: Torque to 113 Nm (83 ft-lbs).

✅ After Repair

• Road test at low speed first. Listen for clunks and verify straight braking.
• Recheck all visible fasteners and bracket routing after the test drive.
• Get a front wheel alignment as soon as possible (recommended same day/within 50 km).
• New struts can feel firmer at first.
