Heavy Duty Replacement Ball Joints | Jeep Cherokee Xj/comanche Mj/wrangler Tj

Built for Jeep owners who want steering precision and durability after a lift install or heavy trail use, these Heavy Duty Replacement Ball Joints upgrade the factory joints that wear quickly under the stress of larger tires and rough terrain. A set of 4 — 2 upper and 2 lower — they're a direct replacement engineered to outlast OE components and restore tight, responsive handling.

Installed and serviced at Road Runner Wheels & Tires. Most suspension upgrades go in the same day. Call (678) 400-6467 to schedule.

What's included

• Chromoly ball stud — oil-quenched and tempered for strength, with spiral grooves that ensure consistent lubrication during intense use and trail duty.
• Carburized alloy housing — provides structural durability and corrosion resistance in demanding off-road conditions.
• Polyurethane dust boot — seals out contaminants while allowing full grease access for long-term joint health.
• Metal-on-metal design — eliminates plastic and polymer wear points for a longer service life compared to inferior OE-style joints.
• Fully greaseable — allows periodic maintenance to extend joint life and maintain smooth steering feel.
• Dana 30 & Dana 44 compatibility — works with all aftermarket axle shafts and factory configurations on your XJ, MJ, YJ, or TJ.

Important notes

• Break-in period — Metal-on-metal ball joints require a 100–500 mile break-in. During this time, steering may feel hesitant to return to center and heavier than stock. After break-in, steering will feel tight and smooth.
