How to Replace Front Struts on a 2014-2019 Toyota Highlander (DIY Guide) (Engine: V6 3.5L)
Step-by-step instructions with tools, parts list, safety tips, and alignment/torque spec guidance for 2014, 2015, 2016, 2017, 2018, 2019
🔧 Highlander - Strut Replacement
On your Highlander, the front suspension uses strut assemblies, but the rear is typically a separate shock + coil spring (not a strut). The exact procedure, tool list, and especially the torque specs depend on whether you’re doing the front struts, the rear shocks/springs, or both.
Difficulty Level: Advanced | Estimated Time: 3-6 hours
⚠️ Safety & Precautions
- ⚠️ Never loosen the center strut nut with the spring loaded; a compressed spring can release violently.
- ⚠️ Use jack stands on the proper lift points; never rely on a jack alone.
- ⚠️ Keep hands clear of pinch points when lowering/raising the control arm or knuckle.
- ⚠️ If you remove/loosen suspension alignment bolts, you’ll need a professional alignment afterward.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Safety glasses
- Mechanic gloves
- Breaker bar (1/2" drive)
- Torque wrench (20-200 ft-lbs range)
- Socket set (8mm-22mm)
- Wrench set (10mm-22mm)
- Pry bar (18")
- Needle-nose pliers
- Trim clip tool
- Penetrating oil
- Paint marker
- Spring compressor (external, threaded-rod type) (specialty)
- Allen/hex key set (metric)

📋 Before You Begin
- Park on level ground, set the parking brake, and chock the rear wheels.
- Loosen lug nuts slightly using a 21mm socket and breaker bar before lifting.
- Spray penetrating oil on strut-to-knuckle fasteners and sway-bar link nuts.
- Two quick questions so I can give exact, trim-correct steps + torque specs:
- Are you replacing the front struts, the rear shocks/springs, or all four corners?
- Did you buy complete quick-strut assemblies, or are you transferring the original springs to new struts?
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm your replacement type (needed for safe steps)
- If you have quick-struts, you do not use a spring compressor.
- If you are reusing springs, you must use a spring compressor (specialty) (a tool that clamps the coil spring so it can’t expand).
- Reply with your two answers above and I’ll provide the full numbered procedure with Toyota torque specs for your Highlander.
Step 2: Safety hold (do not proceed yet)
- Do not remove the strut top-center nut without the spring safely compressed or a complete assembly installed.
- Do not loosen alignment/knuckle bolts until you’re ready to support the knuckle and brake hose routing.
✅ After Repair
- Get a 4-wheel alignment after any front strut replacement.
- Test drive slowly first; listen for clunks and re-check fasteners.
- Re-torque lug nuts with a torque wrench after a short drive.
