Spicer Front Upper & Lower Ball Joint Kit for Jeep Wrangler JK & Grand Cherokee WJ (Dana 30)

Eliminate front-end steering play and restore precise alignment to your rig with this genuine Spicer Upper and Lower Ball Joint Kit. Specially packaged for 2007–2018 Jeep Wrangler JK and 1999–2004 Jeep Grand Cherokee WJ models equipped with a Dana 30 front axle, this service kit includes the premium components required to fully refresh one side of your steering setup.

Oversized off-road tires, heavy aftermarket bumpers, and demanding trail use place immense leverage on factory suspension hardware. Over time, ball joints lose their factory tension, causing vague steering feedback, uneven tire wear, and dangerous front-end shimmies like the infamous "death wobble." Engineered by Spicer to meet strict OEM standards, these heavy-duty ball joints feature heat-treated steel construction and advanced sealing boots to lock out trail grit and moisture far better than standard economy replacements.

Kit Highlights:

• Complete Single-Side Service: Bundles one upper ball joint, one lower ball joint, and all necessary installation hardware (including cotter pins, castle nuts, and snap rings) for a complete swap.

• Genuine Spicer OEM Quality: Precision-machined from high-grade, heat-treated steel to withstand high-impact loads and ensure long-term structural integrity.

• Restores Ride & Handling: Tightens up loose knuckle tolerances to get rid of steering play, highway wandering, and front-end clunking.

• Direct Drop-In Fitment: Mapped precisely to factory measurements for a seamless installation inside your front axle's outer inner-C forgings.
