Spicer Front Upper & Lower Ball Joints & Axle U-Joint Master Overhaul Kit for 2007-2018 Jeep Wrangler JK Sport & Sahara (Dana 30, Both Sides)

Eliminate loose steering play, correct front-end wander, and stop harsh axle binding or clicking noises with this premium Spicer Front Ball Joint & Axle Shaft U-Joint Master Combo Kit. Specifically engineered as a high-durability, complete original equipment replacement bundle for 2007–2018 Jeep Wrangler JK standard (non-Rubicon) models, this package contains all the primary structural and drivetrain components required to fully rebuild both the driver and passenger side wheel ends on factory Dana 30 solid front axles.

Over years of daily commuting, highway cruising, and demanding trail riding with suspension lifts and oversized off-road tires, the front wheel ends of your JK take a massive beating. The factory ball joints naturally lose their internal lubrication and develop slack, leading to steering wheel wander, uneven tire tread wear, and the infamous front-end steering oscillation known as "death wobble." Simultaneously, the needle bearings inside the front axle shaft universal joints dry up and seize from water entry during mud or stream crossings. A failing u-joint will cause a loud clicking or popping noise when turning in 4WD, heavy steering feedback, and can ultimately snap on the trail, destroying your inner and outer axle yokes.

This original equipment manufacturer (OEM) master overhaul package eliminates the hassle of sourcing individual parts by bundling a full dual-side set of premium Spicer upper and lower ball joints with a matching pair of heavy-duty Spicer solid-cross axle shaft u-joint replacements. Sourcing a genuine Spicer bundle guarantees cold-forged steel strength, advanced multi-lip synthetic rubber seals, and precision-machined tolerances that mirror original factory blueprints for an exact press-fit.
