🔧 Grand Cherokee - Front Ball Joint Replacement

Replacing the front ball joints restores tight steering and removes clunks caused by worn suspension joints. On your Grand Cherokee, the front ball joints are pressed into the steering knuckle, so this job requires a ball joint press and careful support of the suspension.

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

⚠️ Safety & Precautions

• ⚠️ Always support your Grand Cherokee with jack stands. Never rely on a floor jack alone.
• ⚠️ Wear safety glasses. Pressed ball joints can release suddenly.
• ⚠️ Do not let the brake caliper hang by the brake hose. Support it with a bungee cord.
• ⚠️ Keep the axle, ABS wire, and brake hose from being stretched or pulled.
• ⚠️ If equipped with Quadra-Lift air suspension, enable Tire/Jack Mode before lifting.
• ⚠️ A wheel alignment is required after this repair.
