How to Replace Front Struts & Rear Shocks on a 2018 Acura MDX (DIY Guide)
Step-by-step instructions with required tools, parts checklist, safety tips, and alignment recommendations


🔧 MDX - Shock Absorber/Strut Replacement
On your MDX, the front suspension uses struts (shock + spring assembly) and the rear uses shocks (separate from the spring). The steps, parts, and torque specs change a lot depending on whether you’re doing the front, rear, or all four.
Difficulty Level: Intermediate | Estimated Time: 2-6 hours
Two quick questions so I can give you the exact OEM-correct steps and torque specs:
- ❓ Are you replacing front struts, rear shocks, or all four?
- ❓ For the front, are you installing complete strut assemblies (quick-struts) or reusing the springs (requires a spring compressor)?
⚠️ Safety & Precautions
- ⚠️ Never work under the MDX supported only by a jack; use jack stands on solid ground.
- ⚠️ Suspension parts can release stored energy; if reusing front springs, a spring compressor is required (this tool compresses the coil spring so it can’t “jump”).
- ⚠️ If you disconnect any ABS/brake line brackets, do not let the caliper/knuckle hang by hoses or wires.
- ⚠️ Final tightening of suspension bolts should be done at normal ride height to avoid bushing damage.
- 🔋 Battery disconnect is usually not required for shocks/struts.

📋 Before You Begin
- 🅿️ Park on level ground, shift to P, and set the parking brake.
- Use wheel chocks at the wheels staying on the ground.
- Crack the lug nuts loose with a 21mm socket and breaker bar before lifting.
- Spray visible shock/strut fasteners with penetrating oil and wait 10 minutes.
- Plan an alignment after front strut work (recommended anytime struts are removed).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm which corners you’re replacing
- Please reply: front, rear, or all four.
- Please reply: quick-struts or reuse springs.
- Once you answer, I’ll give the exact OEM-correct removal/installation steps and Torque to XX Nm (YY ft-lbs) specs for each fastener.
Step 2: Do not begin spring disassembly yet (if front)
- If you are reusing springs, do not remove the center strut nut until the spring is compressed with a spring compressor (specialty).
- Spring force can cause severe injury.
✅ After Repair
- Re-check lug nut torque with a torque wrench after a short test drive.
- Listen for clunks over bumps; a clunk often means a mount/hardware issue.
- Get a 4-wheel alignment if front struts were replaced.
