⚠️ Safety & Precautions

• ⚠️ Work on level ground and support your Grand Cherokee with jack stands before going underneath.
• ⚠️ Never rely on a floor jack alone. A floor jack lifts the vehicle; jack stands hold it safely.
• ⚠️ Replace rear shock absorbers in pairs so both sides handle the same.
• ⚠️ Do not remove suspension arms or springs for this job. The rear coil springs stay installed.
• ⚠️ If your Grand Cherokee has load-leveling rear shocks, replace with the correct matching type.

📋 Before You Begin

• Park your Grand Cherokee on flat, solid ground.
• Shift to Park and apply the parking brake.
• Place wheel chocks in front of the front tires. Wheel chocks are wedges that stop the vehicle from rolling.
• Spray penetrating oil on the upper and lower rear shock bolts before starting.
• Loosen the rear wheel lug nuts slightly before lifting the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Wheel Lug Nuts

• Use the 21mm lug nut socket and 1/2-inch drive breaker bar to loosen each rear lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Lift and Support the Rear of the Vehicle

• Use the floor jack to lift the rear of your Grand Cherokee at the rear axle area.
• Place jack stands under safe rear support points on both sides.
• Lower the vehicle gently onto the jack stands.
• Keep the floor jack lightly supporting the rear axle so it does not drop when the shock is removed.

Step 3: Remove the Rear Wheels

• Use the 21mm lug nut socket and 1/2-inch drive ratchet to remove the rear lug nuts.
• Remove both rear wheels and set them flat on the ground.

Step 4: Support the Rear Axle

• Use the floor jack under the rear axle tube near the shock you are replacing.
• Raise the jack just enough to take weight off the shock bolts.
• This makes the bolts easier to remove and keeps the axle from dropping suddenly.

Step 5: Remove the Lower Shock Bolt

• Use the 18mm socket, 18mm wrench, and 1/2-inch drive ratchet to remove the lower shock mounting bolt and nut.
• If the bolt is stuck, spray more penetrating oil and tap it gently with the rubber mallet.
• Use the small pry bar only if needed to relieve light pressure on the shock eye.

Step 6: Remove the Upper Shock Bolt

• Use the 18mm socket, 18mm wrench, and 1/2-inch drive ratchet to remove the upper shock mounting bolt and nut.
• Hold the shock with one hand as the bolt comes out so it does not fall.
• Remove the old shock absorber from the vehicle.

Step 7: Compare the New Shock to the Old Shock

• Set the old and new shock absorbers side by side.
• Make sure the length, mounting ends, and bushing style match.
• A bushing is the rubber sleeve inside the shock mount that reduces vibration.

Step 8: Install the New Upper Shock Mount

• Position the new shock absorber in the upper mount.
• Slide the upper bolt through by hand first to avoid cross-threading.
• Use the 18mm socket, 18mm wrench, and 1/2-inch drive ratchet to snug the upper bolt.
• Do not fully torque it yet.

Step 9: Install the New Lower Shock Mount

• Use the floor jack to slightly raise or lower the rear axle until the lower shock eye lines up with the bracket.
• Install the lower bolt by hand first.
• Use the 18mm socket, 18mm wrench, and 1/2-inch drive ratchet to snug the lower bolt.
• Hand-start bolts to protect threads.

Step 10: Torque the Shock Bolts

• Use the torque wrench, 18mm socket, and 18mm wrench to tighten the upper shock bolt.
• Torque to 100 Nm (74 ft-lbs).
• Use the torque wrench, 18mm socket, and 18mm wrench to tighten the lower shock bolt.
• Torque to 100 Nm (74 ft-lbs).

Step 11: Repeat on the Other Side

• Move the floor jack to support the opposite side of the rear axle.
• Repeat Steps 5 through 10 for the other rear shock absorber.
• Always replace both rear shocks during the same repair.

Step 12: Reinstall the Rear Wheels

• Place each rear wheel back onto the hub.
• Use the 21mm lug nut socket and 1/2-inch drive ratchet to install the lug nuts by hand first.
• Snug the lug nuts in a star pattern.

Step 13: Lower the Vehicle and Torque Lug Nuts

• Use the floor jack to lift the rear slightly off the jack stands.
• Remove the jack stands.
• Lower your Grand Cherokee fully to the ground.
• Use the torque wrench and 21mm lug nut socket to tighten the rear lug nuts in a star pattern.
• Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• Push down firmly on the rear bumper and release. The vehicle should rise and settle quickly without bouncing several times.
• Drive slowly around the block and listen for clunks or rattles.
• Recheck that the shock bolts are tight after the test drive.
• Recheck rear lug nut torque after 25-50 miles.
• If the rear still sags, bounces, or sits unevenly, inspect the springs, bushings, and rear suspension links.
