Spicer Front Steering Knuckle Ball Joint Kit for 2007-2016 Jeep Wrangler JK & Unlimited (Dana 30 / Dana 44, Both Sides)

Eliminate erratic steering wander, conquer the dreaded front-end death wobble, and restore crisp, confident handling to your rig with this genuine Spicer Front Steering Knuckle Ball Joint Kit. Specially engineered for 2007–2016 Jeep Wrangler JK and JK Unlimited (2-Door & 4-Door) models—including Sport, Sahara, and Rubicon trims—this premium master chassis package includes all the heavy-duty upper and lower ball joints required to completely rebuild both the driver and passenger sides of your front axle.

On the JK platform, the front ball joints endure constant stress from daily commuting, trailing, and the added leverage of larger aftermarket off-road tires. Over time, factory joints develop vertical and lateral play, resulting in loose steering feedback, uneven tire tread wear, and harsh front-end clunking over bumps. This genuine Spicer OEM service bundle updates your front-end steering geometry with professional-grade forgings designed to handle high torsional loads. Each component features exact dimensional indexing to guarantee a reliable, high-pressure press-fit into your factory axle yokes and steering knuckles.

Kit Highlights:

• Complete Axle Overhaul Bundle: Contains 2 upper ball joints, 2 lower ball joints, premium cotter pins, castle nuts, snap rings, and specialized hardware required to service both front steering knuckles simultaneously.

• Genuine Spicer OEM Quality: Manufactured by the original equipment supplier to meet strict structural and material tolerances, providing far greater longevity than generic aftermarket alternatives.

• Heavy-Duty Forged Steel Construction: Heat-treated internal ball studs and premium housings prevent deflection and resist stretching under intense off-road trail conditions or heavy hauling.

• Restores Steering Precision: Engineered to original equipment specifications to eliminate loose tracking, death wobble triggers, and front-end mechanical play.
