🔧 Grand Cherokee - Front Strut Assembly Replacement

This job replaces the front strut assemblies on your Grand Cherokee. The strut supports vehicle weight, controls bounce, and helps keep the tires planted, so worn struts can cause clunking, nose-diving, uneven tire wear, and poor handling.

Difficulty Level: Advanced | Estimated Time: 3-5 hours

Assumption: This guide covers the front conventional strut assemblies. If your Grand Cherokee has air suspension components involved, do not disconnect air lines without the factory service procedure.

⚠️ Safety & Precautions

• ⚠️ Replace front struts in pairs so braking and handling stay balanced.
• ⚠️ The front coil spring is under very high tension. Use complete loaded strut assemblies when possible.
• ⚠️ Do not remove the center strut shaft nut unless the spring is safely compressed with a proper spring compressor.
• ⚠️ Support your Grand Cherokee with jack stands. Never work under a vehicle supported only by a jack.
• ⚠️ Keep brake hoses, ABS wiring, and the wheel speed sensor harness from being stretched.
• ⚠️ Disconnecting the battery is not normally required for this repair.

📋 Before You Begin

• Park your Grand Cherokee on level ground and set the parking brake.
• Place wheel chocks behind the rear wheels.
• A loaded strut assembly means the spring, strut, mount, and bearing are already assembled.
• A torque wrench tightens bolts to an exact tightness. This prevents loose bolts and damaged threads.
• Spray penetrating oil on the lower strut bolt and stabilizer link nut before starting.
• Plan for a wheel alignment after the repair. Strut replacement can change alignment angles.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use the 22mm lug nut socket and 1/2-inch drive breaker bar to loosen each front lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Raise and Support the Front

• Use the floor jack to lift the front of your Grand Cherokee at the front crossmember lift point.
• Place jack stands under the proper front frame support points.
• Lower the vehicle gently onto the stands using the floor jack.
• Keep the jack lightly touching the front crossmember as backup support.

Step 3: Remove the Front Wheels

• Use the 22mm lug nut socket to remove the lug nuts.
• Remove both front wheels and place them flat under the sides of the vehicle as extra safety backup.

Step 4: Open Access to the Upper Strut Mount

• Open the hood.
• Use the trim clip removal tool to remove any plastic push clips blocking access to the upper strut mount area.
• Use the 10mm socket if a small cover or bracket needs to be moved for access.
• Do not remove the large center nut on top of the strut.

Step 5: Support the Lower Control Arm

• Place the floor jack under the outer lower control arm, close to the ball joint area.
• Raise the jack slightly until it supports the arm without lifting the vehicle off the jack stand.
• The lower control arm is the strong metal arm that connects the wheel hub area to the vehicle frame.

Step 6: Disconnect the Stabilizer Bar Link from the Strut

• Use the 18mm socket and 18mm wrench to remove the stabilizer bar link nut from the strut bracket.
• If the stud spins, hold the stud with the correct wrench while turning the nut with the 18mm wrench.
• Move the link away from the strut.
• A stabilizer bar link connects the suspension to the sway bar, which helps reduce body roll in turns.

Step 7: Release Brake Hose and ABS Wire Brackets

• Use the 10mm socket or trim clip removal tool to detach the brake hose bracket and ABS wire retainers from the strut body.
• Use needle-nose pliers only if a small clip needs gentle help releasing.
• Do not pull on the brake hose or ABS wire.

Step 8: Mark the Lower Strut Position

• Use the paint marker to mark the relationship between the lower strut clevis and the lower control arm.
• This helps you install the new strut close to the old position before alignment.

Step 9: Remove the Lower Strut Fastener

• Use the 24mm socket, 24mm wrench, and 1/2-inch drive breaker bar to loosen the lower strut-to-control-arm nut and bolt.
• Remove the nut first, then slide the bolt out.
• If the bolt is tight, use the rubber mallet to gently tap it out while supporting the control arm with the floor jack.

Step 10: Remove the Upper Strut Mount Nuts

• Use the 15mm wrench or 15mm socket to remove the three upper strut mounting nuts.
• Keep one hand on the strut from below while removing the last nut.
• Do not remove the center shaft nut.

Step 11: Remove the Strut Assembly

• Lower the floor jack under the lower control arm slowly until the strut has room to move.
• Use the pry bar 18-inch carefully if the lower strut clevis needs help separating from the control arm.
• Guide the strut assembly down and out through the wheel opening.
• Watch the brake hose closely.

Step 12: Compare Old and New Strut Assemblies

• Place the old and new struts side by side.
• Confirm the mounting studs, lower clevis shape, brake hose bracket, and sway bar link bracket match.
• Use shop rags to clean the mounting areas before installing the new strut.

Step 13: Install the New Strut Assembly

• Guide the new loaded strut assembly into the wheel well.
• Line up the upper studs with the body holes.
• Install the new upper mounting nuts by hand first.
• Use the 15mm socket and 3/8-inch drive torque wrench to tighten the upper strut mount nuts to Torque to 47 Nm (35 ft-lbs).

Step 14: Attach the Lower Strut Mount

• Use the floor jack to slowly raise or lower the control arm until the lower strut mount lines up.
• Slide the new lower bolt through the mount by hand.
• Install the new nut by hand.
• Use the 24mm socket, 24mm wrench, and 1/2-inch drive torque wrench to tighten the lower strut fastener to Torque to 203 Nm (150 ft-lbs).

Step 15: Reconnect the Stabilizer Bar Link

• Install the stabilizer bar link into the strut bracket.
• Use the 18mm socket, 18mm wrench, and 3/8-inch drive torque wrench to tighten the link nut to Torque to 95 Nm (70 ft-lbs).

Step 16: Reattach Brake Hose and ABS Wire Brackets

• Use the 10mm socket to reinstall the brake hose bracket fastener if removed.
• Tighten small bracket bolts to Torque to 10 Nm (89 in-lbs).
• Use the trim clip removal tool or your fingers to seat ABS wire retainers fully into the strut bracket.
• Turn the steering by hand left and right to confirm the wire and hose do not stretch.

Step 17: Repeat on the Other Side

• Repeat Steps 5 through 16 on the opposite front strut.
• Replace both sides before driving.

Step 18: Reinstall the Front Wheels

• Install the wheels onto the hubs.
• Thread the lug nuts by hand first to avoid cross-threading.
• Use the 22mm lug nut socket to snug the lug nuts in a star pattern.

Step 19: Lower the Vehicle and Torque the Wheels

• Use the floor jack to raise the vehicle slightly and remove the jack stands.
• Lower the vehicle until the tires touch the ground.
• Use the 22mm lug nut socket and 1/2-inch drive torque wrench to tighten lug nuts in a star pattern to Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• ✅ Bounce-test the front corners. The body should settle quickly without repeated bouncing.
• ✅ Test drive slowly first. Listen for clunks, rattles, or rubbing.
• ✅ Recheck that brake hoses and ABS wires are clipped in place after the test drive.
• ✅ Have a professional wheel alignment performed as soon as possible.
• ✅ Recheck lug nut torque after 25-50 miles to 176 Nm (130 ft-lbs).
