🔧 F-150 - Front Strut Assembly Replacement

On your F-150, the “strut” is the front shock/coil assembly. Replacing it restores ride control and fixes clunks, bouncing, or uneven tire wear caused by worn struts/mounts.

Difficulty Level: Intermediate | Estimated Time: 2.5-5.0 hours (both fronts)

⚠️ Safety & Precautions

• ⚠️ Support the truck with jack stands; never rely on a jack.
• ⚠️ Do not remove the center nut on top of the strut unless you are using a spring compressor (the coil spring is stored energy).
• ⚠️ Keep hands clear when lowering/raising the lower control arm.
• ⚠️ If using a spring compressor: it’s a specialty tool; misuse can cause severe injury.
• ⚠️ No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen lug nuts and lift the front

• Use a 21mm socket and breaker bar to crack the lug nuts loose (about 1/2 turn).
• Lift the front with a floor jack (rated 3-ton minimum) at the front crossmember.
• Set the frame onto jack stands (rated 3-ton minimum) and gently lower the truck onto them.
• Remove the wheel using the 21mm socket.

Step 2: Free the strut from hoses/brackets

• Locate the brake hose/ABS wire brackets near the strut area.
• Use a 10mm socket (or the correct size present) to remove any small bracket bolts, then move the lines aside so they won’t get stretched.
• Use needle-nose pliers and a flat trim tool if you need to pop any plastic clips free.

Step 3: Disconnect the sway bar end link (if it blocks strut removal)

• At the lower control arm, remove the sway bar end link nut using an 18mm socket and 18mm combination wrench.
• If the stud spins, hold it with the wrench while turning the nut with the socket.

Step 4: Support the lower control arm

• Place the floor jack (rated 3-ton minimum) under the lower control arm and apply light upward pressure.
• This keeps the suspension from dropping suddenly when the strut bolt comes out.

Step 5: Remove the lower strut bolt/nut

• Use a paint marker to mark the bolt/nut position (helps you reassemble consistently).
• Remove the lower strut bolt/nut using an 18mm socket and 18mm combination wrench.
• If the bolt is stuck, tap it out with a hammer (16 oz) while supporting the strut with your other hand.

Step 6: Remove the upper strut mount nuts

• Under the hood, locate the top of the strut tower.
• Remove the 3 upper mount nuts using a 15mm socket.
• Do not remove the center strut shaft nut. (That’s the one holding the spring to the strut.)

Step 7: Remove the strut assembly

• Lower the floor jack (rated 3-ton minimum) slightly to create clearance.
• Work the strut out of the wheel well. Use a pry bar (18") gently if needed to clear the lower mount.

Step 8: Install the new strut assembly

• Position the new strut into the tower first, then start the 3 top nuts by hand using the 15mm socket (do not fully tighten yet).
• Align the lower strut mount and insert the lower bolt. Use the hammer (16 oz) lightly if needed.

Step 9: Tighten fasteners to spec

• Tighten the 3 upper strut mount nuts using the torque wrench: Torque to 46 Nm (34 ft-lbs).
• Tighten the lower strut bolt/nut using the torque wrench: Torque to 350 Nm (258 ft-lbs).
• If removed, tighten the sway bar end link nut using the torque wrench: Torque to 85 Nm (63 ft-lbs).
• Reinstall any brake hose/ABS brackets using the 10mm socket snugly.

Step 10: Reinstall wheel and lower the truck

• Reinstall the wheel and hand-thread all lug nuts.
• Lower the truck off the jack stands using the floor jack.
• Torque lug nuts in a star pattern using the torque wrench: Torque to 203 Nm (150 ft-lbs).

Step 11: Repeat on the other side

• Repeat Steps 1–10 for the other front strut so both sides match.
• Tip: Always replace front struts in pairs.

✅ After Repair

• Start the engine and turn the steering lock-to-lock while parked; listen for clunks.
• Test drive slowly first, then at road speed; verify no pulling, popping, or vibration.
• Get a front-end alignment done soon after replacement to protect tires and handling.
• Recheck lug nut torque after ~80–160 km (50–100 miles) using the torque wrench: 203 Nm (150 ft-lbs).
