🔧 GX460 - Shock Absorber Replacement

On your GX460, the “shocks” are part of the front strut assemblies (shock + coil spring) and separate rear shock absorbers. Replacing them restores ride control, reduces bouncing, and improves braking stability over bumps.

Difficulty Level: Advanced | Estimated Time: 4-7 hours

Assumption: replacing both front strut assemblies and both rear shocks; torque values listed are common GX460 specs—verify with an OEM manual if available.

⚠️ Safety & Precautions

• ⚠️ Support the frame with jack stands; never rely on a jack alone.
• ⚠️ Front coil springs are under heavy tension—use a coil spring compressor correctly, or replace complete strut assemblies to avoid spring transfer.
• ⚠️ Keep hands clear of pinch points when lowering/raising the control arm and rear axle.
• ⚠️ Do not stretch or pull on ABS/brake line brackets and wiring.
• ⚠️ Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks at the tires staying on the ground.
• Loosen lug nuts slightly using a 21mm socket and breaker bar before lifting.
• Spray all shock/strut fasteners with penetrating oil 10–15 minutes before removal.
• If transferring springs: inspect the coil spring, top mount, and isolators; replace worn parts now to avoid doing the job twice.
• Take photos before disassembly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheels

• Lift the front using a floor jack under the front jacking point.
• Support the frame with jack stands.
• Remove the wheels using a 21mm socket.

Step 2: Disconnect brackets and sway bar link from the front strut

• Unbolt the brake hose/ABS wire brackets from the strut using a 10mm socket or 12mm socket (varies by bracket).
• Remove the sway bar end link nut at the strut using a 17mm wrench and 6mm hex key (if the stud spins) or a 17mm socket if it holds.
• Torque to 74 Nm (55 ft-lbs) on reassembly for the end link nut.
• Don’t let the brake line hang.

Step 3: Separate the front strut from the steering knuckle

• Support the lower control arm lightly with the floor jack.
• Remove the two strut-to-knuckle bolts/nuts using a 22mm socket and breaker bar.
• If the bolts are tight, tap them out using a rubber mallet and use a pry bar as needed.
• Torque to 177 Nm (131 ft-lbs) for strut-to-knuckle bolts/nuts on reassembly.

Step 4: Remove the front strut assembly

• Open the hood.
• Remove the three upper strut mount nuts using a 14mm socket. Leave the center nut alone for now.
• Hold the strut so it doesn’t drop, then guide it out of the wheel well.
• Torque to 47 Nm (35 ft-lbs) for upper mount nuts on reassembly.

Step 5: Transfer the spring (only if you are not installing complete strut assemblies)

• Install a coil spring compressor (specialty) on opposite sides of the spring. Tighten evenly until the spring is loose in the top mount.
• Mark the spring orientation with a paint marker so it goes back the same way.
• Remove the strut center nut using a 17mm socket while holding the strut shaft with the appropriate hex key (tool varies by shock design).
• Move the spring and top mount onto the new strut, aligning the spring end to the pocket.
• Tighten the center nut using a torque wrench: Torque to 70 Nm (52 ft-lbs).
• Slowly release the spring compressor, alternating sides evenly.
• Never point the spring at your body.

Step 6: Reinstall the front strut

• Position the strut in the tower and hand-start the three upper nuts using a 14mm socket.
• Align the lower strut bracket to the knuckle, insert both bolts, and install the nuts using a 22mm socket.
• Reconnect the sway bar end link using a 17mm socket / 17mm wrench.
• Reattach brake hose/ABS brackets using a 10mm socket or 12mm socket.
• Final torque:
  • Upper mount nuts: Torque to 47 Nm (35 ft-lbs)
  • Strut-to-knuckle bolts/nuts: Torque to 177 Nm (131 ft-lbs)
  • Sway bar end link nut: Torque to 74 Nm (55 ft-lbs)

Step 7: Lift and remove the rear wheels

• Chock the front wheels with wheel chocks.
• Lift the rear with a floor jack and support the frame with jack stands.
• Keep the rear axle lightly supported by the floor jack so it can move up/down a little.
• Remove the rear wheels using a 21mm socket.

Step 8: Remove the rear shocks

• Remove the lower rear shock bolt/nut using a 19mm socket and breaker bar.
• Remove the upper rear shock nut using a 17mm wrench (hold the shock shaft if it spins using needle-nose pliers on the flat spot, if provided).
• Pull the shock out.
• Torque to 137 Nm (101 ft-lbs) for the lower bolt on reassembly.
• Torque to 25 Nm (18 ft-lbs) for the upper nut on reassembly.

Step 9: Install the rear shocks

• Install the upper bushings/washers in the same order as removed.
• Position the new shock and hand-start the upper nut using a 17mm wrench.
• Line up the lower mount by raising/lowering the axle slightly with the floor jack, then insert the lower bolt and install the nut using a 19mm socket.
• Final torque:
  • Upper nut: Torque to 25 Nm (18 ft-lbs)
  • Lower bolt/nut: Torque to 137 Nm (101 ft-lbs)

Step 10: Reinstall wheels and lower the vehicle

• Install wheels and snug lug nuts using a 21mm socket.
• Lower the vehicle off jack stands using the floor jack.
• Torque lug nuts in a star pattern using a torque wrench: Torque to 131 Nm (97 ft-lbs).

✅ After Repair

• Road test at low speed first. Listen for clunks and confirm the steering feels normal.
• Recheck all visible fasteners and brackets after the test drive.
• Get a 4-wheel alignment as soon as possible after front strut work.
• Expect a slightly firmer ride at first.
