Tools you need for front struts on a 2015-2020 Ford F-150

Moderate · 2-4 hours for the pair · Updated 2026-09-28
Must-have tools
  1. 22 mm socket, 1/2 in drive
  2. 21 mm socket + wrench, 1/2 in drive
  3. 15 mm socket, 3/8 in drive
  4. Torque wrench, 1/2 in drive
  5. Second floor jack for control arm

On the 13th-gen F-150 the front "struts" are really coil-over shock assemblies bolted into a double-wishbone front end: three nuts on top inside the shock tower and one long through-bolt at the bottom into the lower control arm. Buying complete loaded assemblies makes this a bolt-in job with no spring compressor, and tool-wise it is simple: 22 mm for lugs, 15 mm for the top nuts, and a 21 mm socket plus wrench for the bottom bolt. Budget extra time for a seized lower bolt if the truck has seen road salt.

The one thing people get wrong is not supporting the lower control arm. Because the spring sits on the strut, pulling the bottom bolt with the arm hanging free lets everything drop and makes reinstallation a fight; keep a second jack under the outer end of the arm and lower it gradually. The other common miss is torquing the lower through-bolt with the suspension at full droop, which preloads the bushing and shortens its life.

Differences within the 2015-2020 generation

Engine choice (3.3/3.5 V6, 2.7/3.5 EcoBoost, 5.0 V8) does not change any front strut tool sizes - the front suspension hardware is common. What does change things is trim: Raptor uses Fox coil-overs with their own mounting hardware and remote-reservoir routing, and trucks with FX4 off-road packages or aftermarket leveling kits may have spacers or longer upper studs. Lug nuts are 22 mm across the generation.

Torque specs

Wheel lug nuts150 ft-lb (204 Nm)
Strut upper mount nuts (3, 15 mm)46 ft-lb (63 Nm) - verify in the service manual
Strut lower through-bolt/nut at lower control armverify in the service manual (high, roughly 110-130 ft-lb range)

How the job goes

  1. Park on level ground, chock the rear wheels, and loosen the front lug nuts about a half turn while the tires are still down.
  2. Raise the front of the truck and set jack stands under the frame rails behind the lower control arms; let the suspension hang. Remove both front wheels.
  3. Spray penetrating oil on the lower strut through-bolt and nut and let it soak.
  4. If the sway bar link is in the way or you need extra arm travel, unbolt the link from the lower control arm (hold the stud with a hex key if it spins).
  5. Unclip or unbolt any brake hose/ABS wire bracket attached to the strut or nearby so nothing gets stretched.
  6. Place the second jack under the outer end of the lower control arm and raise it slightly to take the load. Do not jack on the ball joint boot.
  7. From the engine bay, remove the three 15 mm nuts on the top of the strut mount. Leave the center rod nut alone on a complete assembly.
  8. Remove the nut from the lower through-bolt, then drive or pull the bolt out of the lower control arm. If it is stuck, spray again and tap it out with a drift, not a hammer on bare threads.
  9. Slowly lower the control arm jack to let the spring extend, then tilt the strut assembly out through the wheel opening.
  10. Compare old and new units: spring height, mount orientation, and the stud pattern on top must match.
  11. Feed the new assembly up into the shock tower, start the three top nuts by hand, and snug them.
  12. Raise the control arm with the jack until the lower eye lines up with the arm, use an alignment punch to center the holes, and push the through-bolt in from the correct side.
  13. Install the lower nut and torque it to spec with the suspension loaded (arm supported), not hanging.
  14. Torque the three upper nuts, reinstall the sway bar link and any brackets, and reattach brake hose/ABS clips.
  15. Repeat on the other side; always replace struts in pairs.
  16. Mount the wheels, lower the truck, and torque the lug nuts to 150 ft-lb in a star pattern.
  17. Bounce the front end, check for clearance at full lock both directions, then test drive and get an alignment.

Watch out

Sizes here (22 mm lugs, three 15 mm upper nuts, 21 mm lower through-bolt hardware) match the common 2015-2020 F-150 layout, but hardware varies slightly by trim and aftermarket kit, so test-fit sockets and confirm all torque values in the Ford service manual before final tightening.

Frequently asked

Do I need an alignment after replacing front struts on an F-150?

Yes, get at least a toe and camber check. The lower through-bolt and strut position can shift camber slightly, and it is cheap compared to chewing up a set of tires.

What size socket are the F-150 front strut bolts?

The three upper mount nuts in the shock tower are 15 mm, the lower control arm through-bolt and nut are typically 21 mm, and the lug nuts are 22 mm. Have both a 3/8 in and 1/2 in drive set on hand.

Can I replace just the shock and reuse the spring?

You can, but you then need a proper coil spring compressor to transfer the spring and upper mount, which is the riskiest part of the job. Most DIYers buy complete loaded assemblies and skip it.

Why won't the lower strut bolt come out of my F-150?

The bolt corrodes to the inner sleeve of the shock bushing. Soak it in penetrating oil, work it back and forth with a wrench, then drive it out with a brass drift or punch - protect the threads and never hammer the exposed thread directly.
