A-Premium Front Upper Ball Joint Pair for Toyota Tacoma 4Runner Tundra Sequoia — OEM Fit, Pre-Greased with Rubber Bushings

The A-Premium Front Upper Ball Joint set replaces both left and right front upper ball joints for compatible Toyota models, restoring steering precision and factory fitment.

If your Toyota Tacoma, 4Runner, Sequoia, or Tundra is showing steering play, uneven tire wear, or front-end noise, this A-Premium front upper ball joint pair is engineered to meet original equipment dimensions for a straightforward swap. Each kit includes a driver-side and passenger-side ball joint manufactured to the same length, stud and bushing diameter as the OEM parts, pre-greased for immediate use and fitted with premium rubber bushings to reduce vibration.

How will these ball joints affect steering feel and noise?

Worn upper ball joints allow movement in the steering knuckle that translates to loose steering, clunks, and irregular tire wear. Replacing both upper joints with A-Premium components reduces unwanted play and helps return steering response closer to factory behavior.

• Pre-greased ball stud for smooth movement out of the box
• Premium rubber bushings that damp road vibration and noise
• OEM-matching dimensions for correct alignment and steering geometry

Will these parts fit my Toyota model and how easy is installation?

The set is built to fit a range of Toyota trucks and SUVs using the original specifications; compatibility spans specific Tacoma years and several 4Runner, Sequoia and Tundra model years. Because the studs, bushings and overall dimensions match OEM, installation aligns with factory mounting points, simplifying replacement for a DIY mechanic or professional installer.
