🔧 Highlander - Shock Absorber Replacement

On your Highlander, the “shocks” can mean the rear shock absorbers and/or the front strut assemblies (the front uses a strut, which is a shock + spring as one unit). The exact steps, required parts, and torque specs change a lot depending on which end you’re doing and whether you’re replacing complete assemblies.

Difficulty Level: Intermediate–Advanced | Estimated Time: 2–6 hours

⚠️ Safety & Precautions

• 🧯 Support the Highlander on jack stands—never rely on a floor jack.
• 🧤 Wear safety glasses and mechanic gloves; suspension bolts can release suddenly.
• ⚠️ Front struts contain a coil spring under high tension. If you’re not using a complete strut assembly, a spring compressor is required and can be dangerous if used wrong.
• 🔥 Let brakes/exhaust cool before working near them.

📋 Before You Begin

• 🅿️ Park on level ground, shift to P, and set the parking brake.
• Block the wheels with wheel chocks.
• Spray visible suspension fasteners with penetrating oil 10–20 minutes before removal.
• If doing front struts, plan for a professional alignment after the job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm what you’re replacing (so I give exact OEM steps & torque)

• Tell me if you’re doing front struts, rear shocks, or both.
• Tell me if you’re installing complete strut assemblies (quick/loaded struts) or reusing your coil springs (requires a spring compressor, a tool that squeezes the spring shorter so it can be removed safely).

Step 2: Don’t loosen anything spring-loaded until confirmed

• Use a lug nut socket (21mm) and breaker bar to crack lug nuts loose 1/4 turn only.
• Use a floor jack and jack stands to safely support the Highlander.
• Stop here and reply to the two questions above so I can give you the correct removal order and Torque to XX Nm (YY ft-lbs) values for your exact setup.

✅ After Repair

• For any suspension work, re-check all fasteners with a torque wrench after a short test drive.
• If you replaced front struts, get a 4-wheel alignment as soon as possible.
• Listen for clunks over bumps; that often indicates a loose mount or sway-bar link.
