How to Replace Front Struts and Rear Shocks on a 2013 Mazda CX-5
Step-by-step DIY suspension replacement with required tools, parts list, safety tips, and alignment guidance for 2013, 2014, 2015, 2016
đź”§ CX-5 - Shock/Strut Replacement
On your CX-5, the front suspension uses struts (shock + spring as an assembly), and the rear uses separate shock absorbers. The steps and tools are different, especially if you’re reusing the front springs.
Difficulty Level: Intermediate | Estimated Time: Rear: 1.5–3.0 hours (both sides) | Front: 3–6 hours (both sides)
⚠️ Safety & Precautions
- 🛑 Support the CX-5 on jack stands—never rely on a floor jack.
- 🛑 If doing front struts and reusing springs: a coil spring compressor is required; springs store dangerous energy.
- 🛑 Do not loosen suspension bolts with the vehicle supported only by the jack.
- 🛑 After suspension work, a 4-wheel alignment is recommended.
đź”§ 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
- Lug wrench or 21mm socket
- Socket set (8mm–21mm)
- Wrench set (8mm–21mm)
- Breaker bar (1/2")
- Torque wrench (10–200 Nm range)
- Penetrating oil
- Pry bar
- Flat trim tool
- Needle-nose pliers
- Paint marker
- Coil spring compressor (specialty)
- Strut spreader tool (specialty)
- Safety glasses
- Mechanic gloves

đź“‹ Before You Begin
- Park on level ground, put the transmission in 1st gear, and set the parking brake.
- Chock the wheels that stay on the ground using wheel chocks.
- Loosen the wheel lug nuts 1/2 turn using a 21mm socket before lifting.
- Spray penetrating oil on the shock/strut bolts using penetrating oil and wait 5–10 minutes.
🔨 Step-by-Step Instructions
Follow these steps in order:
Important: I need one detail to give you correct torque specs and the exact sequence.
- Are you replacing rear shocks, front struts, or all four?
- If front: are you installing complete quick-strut assemblies (prebuilt), or reusing your springs with a spring compressor?
While you confirm, here’s the safe high-level procedure (no torque values yet):
Step 1: Lift and remove the wheels
- Use a floor jack at the proper lift point and set the vehicle on jack stands.
- Remove the wheels using a 21mm socket.
Step 2 (Rear): Remove the rear shock
- Support the rear lower control arm with the floor jack so it doesn’t drop suddenly.
- Remove the lower shock bolt using the appropriate socket and wrench.
- Remove the upper shock mounting hardware (access varies) using a socket and wrench or trim tool if interior panels must be lifted.
- Pull the shock out. Use a pry bar gently if it’s stuck.
Step 3 (Rear): Install the new rear shock
- Install the shock in the upper mount first by hand-threading the fasteners using your hand (no tools yet).
- Align the lower mount and install the lower bolt using a socket and wrench.
- Tip: Jack the control arm slightly to align holes.
Step 4 (Rear): Final tighten at ride height
- With the suspension supported close to normal ride height, tighten the shock fasteners using a torque wrench.
- This helps prevent bushing twist and squeaks.
Step 5 (Front): Remove the strut assembly
- Mark camber/reference positions (if applicable) using a paint marker.
- Detach any brake hose/ABS wire brackets from the strut using the correct socket.
- Loosen the strut-to-knuckle bolts using a breaker bar and the correct socket and wrench.
- Support the knuckle and separate it from the strut; use a strut spreader tool (specialty) if the knuckle clamps the strut.
- From the top mount, remove the mounting nuts using the correct socket, then remove the strut.
Step 6 (Front): Build/Install the strut
- If reusing springs: compress the spring using a coil spring compressor (specialty) until it’s loose in the perch. Tip: Compress evenly, side-to-side.
- Transfer mount/bearing and isolators as needed using the correct socket.
- Install the strut back into the tower, start the top nuts by hand, then attach the knuckle using the correct socket and wrench.
Step 7: Reinstall wheels and lower
- Reinstall wheels using a 21mm socket.
- Lower the CX-5 and final-tighten lug nuts with a torque wrench.
âś… After Repair
- Test drive slowly first. Listen for clunks over small bumps.
- Recheck all visible fasteners and brake hose/ABS wire routing.
- Get a 4-wheel alignment, especially after front strut replacement.
đź’° DIY vs Shop Cost
Shop Cost: $600–$1,600 (parts + labor, rear vs all four)
DIY Cost: $180–$900 (parts only, rear vs all four)
You Save: $420–$700+ by doing it yourself!
Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 2–6 hours.
