🔧 CX-5 - Front Strut Replacement

The beginner-friendly move is replacing both front struts with complete loaded assemblies. The FCS Struts Complete Strut and Coil Spring Assemblies shown in the parts list cost about $137.43 per side and include the springs, avoiding dangerous spring transfer work.

This procedure covers the front pair. Your CX-5 uses separate shock absorbers at the rear, so those follow a different procedure. Replace front struts in pairs, then have the wheel alignment checked.

Difficulty Level: Intermediate | Estimated Time: 4-6 hours

⚠️ Safety & Precautions

• ⚠️ Never work beneath a vehicle supported only by a floor jack. Use properly rated jack stands.
• ⚠️ Do not loosen the large center piston-rod nut on an assembled strut. The coil spring stores enough energy to cause severe injury.
• ⚠️ Complete assemblies are strongly recommended for a first-time repair. Compressing and transferring springs requires professional equipment.
• ⚠️ Disconnect and secure the ABS wheel-speed sensor wiring before moving the steering knuckle. Mazda warns that allowing it to stretch can damage the harness. mcx5.org
• ⚠️ Support the steering knuckle after separating it from the strut. Letting it hang can strain the brake hose, ABS wiring, and drive axle.
• ⚠️ Do not allow the brake caliper to hang from its hose.
• ⚠️ A battery disconnect is not required for complete front-strut replacement.

📋 Before You Begin

• Park your CX-5 on firm, level ground. Shift to Park and apply the parking brake.
• Center the steering wheel and place wheel chocks securely behind both rear tires.
• Confirm that the replacement assemblies are marked left and right. Their hose brackets must face the correct direction.
• Use the 21mm wheel-nut socket and breaker bar to loosen each front wheel nut about one-quarter turn.
• Do not remove the wheel nuts until the vehicle is safely supported by jack stands.
• No infotainment menu, electronic parking-brake service mode, or scan-tool command is needed.
• Plan for a professional alignment immediately after the repair. Mazda’s procedure calls for inspecting and adjusting alignment after strut installation. mcx5.org

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front

• Place the hydraulic floor jack under the approved front-center lifting point and raise your CX-5.
• Position the two jack stands beneath the reinforced side support points.
• Lower the vehicle gently onto the stands. Give it a firm stability check before continuing.
• Keep the floor jack lightly touching the front lifting point as a backup, without carrying the vehicle’s weight.

Step 2: Remove both front wheels

• Use the 21mm wheel-nut socket and ratchet to remove the five nuts from each front wheel.
• Remove both wheels and slide one beneath each reinforced rocker area as an additional safety measure.

Step 3: Record the original strut position

• Use the paint marker to draw reference lines across the steering knuckle and old strut flange.
• These marks provide an installation reference, but they do not replace the final alignment.

Step 4: Disconnect the ABS wiring and brake-hose bracket

• Use the flat-blade trim tool to release the ABS wheel-speed sensor wire from every clip attached to the strut and steering knuckle.
• Disconnect the axle-side ABS harness connector where accessible, then secure the loose harness away from the work area.
• Use the needle-nose locking pliers to withdraw the brake-hose retaining clip without crushing it.
• Lift the brake hose from its strut bracket. Do not open the hydraulic brake connection.

Step 5: Disconnect the sway-bar link

• Place the small support jack beneath the lower control arm and lift only enough to support the suspension.
• Use the 17mm combination wrench to loosen the upper sway-bar link nut.
• If the stud spins, hold its center with the 6mm hex-bit socket while turning the nut with the 17mm wrench.
• Remove the link from the strut bracket and move it aside without pulling its rubber boot.
• Do not damage the boot. A torn boot quickly ruins the link joint.

Step 6: Support the steering knuckle

• Position the small support jack directly under the steering knuckle or lower control-arm area.
• Raise it until the knuckle is supported but the vehicle remains fully seated on both jack stands.
• Secure the knuckle so it cannot fall outward when the lower strut bolts are removed.

Step 7: Remove the two lower strut bolts

• Use the 21mm combination wrench to hold each bolt head.
• Use the 21mm socket and breaker bar to loosen both strut-to-knuckle nuts.
• Remove the nuts, then withdraw the bolts while controlling the knuckle with the support jack.
• Tap stubborn bolts with the rubber mallet. Do not strike the threads with a steel hammer.
• Move the knuckle slightly outward and secure it. Never let it hang from the brake hose or axle.

Step 8: Remove the upper strut-mount nuts

• Open the hood and locate the three small nuts surrounding the strut mount.
• Support the complete strut from beneath with one hand.
• Use the 14mm deep socket, extension, and ratchet to remove the three upper mounting nuts.
• Do not loosen the large center nut.
• Lower and guide the complete strut assembly out through the wheel opening.

Step 9: Compare the replacement assembly

• Place the old and new assemblies beside one another without dismantling either unit.
• Confirm that the overall height, lower bolt holes, upper studs, spring position, and hose brackets match.
• Verify that the part marked left is being installed on the driver side and the part marked right on the passenger side.
• Do not install an assembly with damaged threads, a displaced spring, or a mount that turns roughly.

Step 10: Install the new complete strut

• Guide the complete strut through the wheel opening and insert its three upper studs into the body.
• Install all three upper nuts by hand. Do not use an impact wrench.
• Use the 14mm deep socket and torque wrench to tighten the upper nuts evenly to 49-59 Nm (36-44 ft-lbs).

Step 11: Attach the steering knuckle

• Use the small support jack to align the knuckle with the lower strut flange.
• On the right side, insert the two bolts from the front toward the rear.
• On the left side, insert the two bolts from the rear toward the front. Mazda specifies these installation directions. mcx5.org)
• Thread both nuts by hand before tightening either one.
• Use the 21mm wrench, 21mm socket, and high-capacity torque wrench to tighten both nuts to 222-245 Nm (164-181 ft-lbs). mazbook.ru)

Step 12: Reconnect the sway-bar link

• Adjust the small support jack until the sway-bar link stud enters the strut bracket without force.
• Install the lock nut by hand.
• Hold the stud with the 6mm hex-bit socket if it spins.
• Use the 17mm wrench and torque wrench to tighten the nut to 45-55 Nm (33-41 ft-lbs).

Step 13: Reattach the brake hose and ABS wiring

• Seat the brake hose fully inside its strut bracket.
• Install the retaining clip with the needle-nose locking pliers until it locks into its groove.
• Reconnect the ABS harness connector and press every wiring retainer back into its original location.
• Turn the steering gently from side to side and confirm that neither the hose nor wire stretches, twists, or contacts the tire area.

Step 14: Repeat the procedure on the opposite side

• Repeat Steps 3 through 13 using the opposite complete strut assembly.
• Keep left- and right-side hardware separated so each bolt returns to its correct location.

Step 15: Reinstall the wheels

• Clean loose rust and dirt from the wheel-to-hub contact surfaces with a dry cloth.
• Install each wheel and start all five wheel nuts by hand.
• Use the 21mm wheel-nut socket and ratchet to tighten the nuts lightly in a star pattern.
• Raise your CX-5 with the hydraulic floor jack, remove the jack stands, and lower it until the tires touch the ground.
• Use the 21mm wheel-nut socket and torque wrench to tighten the wheel nuts in a star pattern to 108-147 Nm (80-108 ft-lbs).

✅ After Repair

• ✅ Check that every ABS-wire clip and brake-hose retainer is installed before moving your CX-5.
• ✅ Start the engine and verify that the ABS and stability-control warning lights switch off normally.
• ✅ Turn the steering fully left and right while stationary. Stop if you hear binding, spring popping, or hose contact.
• ✅ Drive slowly around the parking area and listen for clunks before entering normal traffic.
• ✅ Avoid high speeds and hard cornering until a professional wheel alignment is completed.
• ✅ After approximately 80-160 km, recheck wheel-nut torque with the 21mm socket and torque wrench.
• ✅ If the steering wheel sits crooked, the vehicle pulls, or an ABS warning remains on, stop driving and inspect the work.
