🔧 Santa Fe - Strut Replacement

On your Santa Fe, the front suspension uses MacPherson struts (a shock + coil spring in one unit). Replacing worn struts restores ride control, braking stability, and reduces clunks/bouncing.

Assumption: You’re replacing the front struts; rear uses separate shocks (procedure included below in case you meant rear).

Difficulty Level: Advanced | Estimated Time: 4-7 hours

⚠️ Safety & Precautions

• ⚠️ Coil springs store huge energy—use a coil spring compressor (specialty) correctly or choose complete strut assemblies to avoid spring transfer.
• ⚠️ Support the vehicle with jack stands on solid ground—never rely on a jack.
• ⚠️ Keep the steering knuckle supported so you don’t over-stretch the CV axle (front drive axle) or damage the ABS wire (wheel speed sensor wiring).
• ⚠️ If your Santa Fe has HID/LED leveling or ride-height sensor links, don’t pry on them.
• ⚠️ Battery disconnect is not required, but keep the key away from the vehicle so the steering doesn’t move unexpectedly.

📋 Before You Begin

• Park on level ground, straighten the steering wheel, and chock the rear wheels.
• Loosen the front lug nuts with a 21mm socket before lifting.
• Spray penetrating oil on the strut-to-knuckle bolts and sway bar end link nuts.
• If you are not using complete strut assemblies: set up the coil spring compressor (a clamp tool that safely squeezes the spring) on a bench—not on the car.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of the Santa Fe

• Use a floor jack (rated 3-ton minimum) to lift at the front center jacking point.
• Place jack stands (rated 3-ton minimum) under the front pinch welds or subframe points.
• Remove the wheels using a 21mm socket.

Step 2: Unclip ABS wire and brake hose brackets from the strut

• Use a trim clip tool and needle-nose pliers to remove clips and free the ABS wire from the strut.
• Remove any small bracket bolts using a 12mm socket.
• Don’t pull on the wire—unclip it.

Step 3: Disconnect the sway bar end link from the strut

• Hold the end link stud with a 6mm Allen key (if equipped) and remove the nut with a 17mm socket or wrench set (metric).
• If the nut is stuck, re-spray penetrating oil and use a breaker bar 1/2".

Step 4: Mark camber position (if your Santa Fe uses camber bolts)

• Use a paint marker to mark the relationship between the strut and the steering knuckle.
• This helps keep alignment close enough to drive to the shop.

Step 5: Remove strut-to-knuckle bolts

• Support the lower control arm/knuckle with a floor jack (rated 3-ton minimum) so it doesn’t drop.
• Remove the two large bolts/nuts using a 21mm socket and 22mm socket with a breaker bar 1/2".
• If the bolts are stuck, use a hammer and punch set to drive them out carefully.
• Torque to factory specification on reassembly (these are high-torque fasteners).

Step 6: Remove the strut top mount nuts

• Open the hood and locate the strut tower.
• Remove the three top mount nuts using a 14mm socket.
• Leave the center strut nut alone unless you are swapping springs.

Step 7: Remove the strut assembly

• Pull the strut outward and down from the knuckle area.
• Use a pry bar only as needed, and keep the knuckle supported so the CV axle doesn’t over-extend.

Step 8: If using complete strut assemblies (recommended), install the new strut

• Guide the new strut into the strut tower and start the three top nuts by hand using a 14mm socket (do not fully tighten yet).
• Align the strut with the knuckle and insert the two large bolts. Use a hammer lightly if needed.
• Tighten the strut-to-knuckle nuts using a torque wrench 1/2": Torque to factory specification.
• Tighten the top mount nuts using a torque wrench 3/8": Torque to factory specification.

Step 9: If transferring springs (only if you are NOT using complete assemblies)

• Install the coil spring compressor (specialty) on opposite sides of the spring and compress evenly until the spring is loose in the seat.
• Remove the center strut nut using a strut nut pass-through socket set (specialty) while holding the shaft with the appropriate bit.
• Move the spring, upper mount, bearing, dust boot, and bump stop to the new strut in the same order.
• Install the center nut and Torque to factory specification, then slowly release the spring compressors evenly.
• If anything binds, stop and reset the compressors.

Step 10: Reconnect sway bar end link, ABS wire, and brake hose bracket

• Reconnect the sway bar end link nut using a 17mm socket and hold the stud with a 6mm Allen key if needed.
• Torque to factory specification.
• Reinstall all brackets using a 12mm socket and re-clip wiring with needle-nose pliers.

Step 11: Reinstall wheels and lower the vehicle

• Install wheels and hand-tighten lug nuts using a 21mm socket.
• Lower the vehicle using a floor jack (rated 3-ton minimum).
• Tighten lug nuts in a star pattern using a torque wrench 1/2": Torque to 132 Nm (97 ft-lbs).

Step 12: Rear note (if you meant “rear struts”)

• Your Santa Fe typically uses rear shocks (not struts). Replacement is similar but easier: support the rear suspension with a floor jack, remove lower shock bolt with a 17mm socket/19mm socket, then remove upper mount nuts/bolt(s) with a 14mm socket.
• Torque to factory specification for upper and lower shock fasteners.

✅ After Repair

• Double-check that ABS wires and brake hoses are clipped and not twisted.
• Road test at low speed first. Listen for clunks over bumps.
• Get a 4-wheel alignment as soon as possible (front strut removal can change camber/toe).
• Recheck lug nut torque with a torque wrench 1/2" after 25–50 miles.
