🔧 CX-50 - Strut Replacement

Struts support your A4’s ride height and control bouncing. On your CX-50, the steps and torque specs change depending on whether you’re doing the front (strut) or the rear (shock) and whether you’re installing complete assemblies or transferring the coil spring.

Before I give the exact step-by-step with Mazda torque specs, answer these 2 quick questions:
1) Are you replacing the front struts, rear shocks, or all four?
2) Are you installing complete “quick-strut” assemblies (pre-assembled) or bare struts/shocks (re-using the coil spring/mounts)?

Difficulty Level: Intermediate | Estimated Time: 2-5 hours

⚠️ Safety & Precautions

• 🛑 Use jack stands—never work under a vehicle on a jack.
• 🛑 If you are transferring springs: a spring compressor stores dangerous energy; use only a high-quality, matched-pair compressor and keep hands/face out of the spring path.
• 🛑 Support the knuckle/control arm so the CV axle and brake hose/ABS wire are not stretched.
• 🛑 If any sensors/brackets are removed, reinstall exactly as found to avoid ABS/traction warnings.
• 🛑 Battery disconnect is usually not required, but keep the key away and ignition OFF while working near ABS wiring.
