A-Premium Front Upper & Lower Ball Joint Kit — Ford Ranger & Mazda B-Series 1998–2011, Pre-Greased

The A-Premium Front Upper & Lower Ball Joint Kit is a complete front suspension replacement set engineered to restore steering precision and reduce suspension noise for compatible Ford Ranger and Mazda B-series trucks.

This kit supplies both upper and lower front ball joints pre-greased and ready to install on select rear-wheel-drive models equipped with front coil springs. Designed as a direct-fit replacement for original suspension components, the set addresses common symptoms of worn ball joints—like looseness in the steering, clunks over bumps, and uneven tire wear—while using durable materials and rubber bushings to damp vibrations and limit noise.

Which vehicles will accept this A-Premium ball joint kit?

The kit fits Ford Ranger trucks from 1998 through 2011 and multiple Mazda B-series pickup years. It is intended only for rear-wheel-drive models with front coil springs and will not fit trucks that use a front torsion bar spring.

• Ford Ranger: 1998–2011 (RWD, front coil spring models)
• Mazda B2300: 2001–2010; B2500: 1998–2001
• Mazda B3000: 1998–2007; B4000: 1998–2003
• Not compatible with torsion-bar front suspension variants

How does this kit improve steering and ride comfort?

Worn ball joints allow unwanted play between the wheel assembly and control arm, producing sloppy steering and inconsistent tire contact. Replacing both upper and lower joints with matched, pre-greased components restores proper steering geometry and reduces vibration transfer into the cabin.

• Restores tight steering feel and consistent wheel alignment
• Rubber bushings absorb road shock and diminish squeaks
• Pre-greased fittings promote smooth articulation and extended service life
• Steel ball stud resists wear under load and temperature changes

What exactly is included in the package and what are the part references?

The shipment contains a balanced set: two front upper ball joints and two front lower ball joints plus the necessary hardware as pictured. Each joint arrives pre-greased and ready for installation, with grease fittings and accessory parts included for a straightforward swap.

• Contents: 2x front upper ball joints and 2x front lower ball joints
• Condition: Brand new, pre-greased, grease fitting included
• Materials: steel ball studs and high-strength housings with rubber bushings
• Reference part numbers: K8771T, K8771, K8738

What should I expect during installation and maintenance?

Installation typically requires basic suspension tools and a safe method to support the vehicle and control arms. Because the joints are pre-greased and supplied with fittings, final lubrication and torqueing to factory specifications are the main tasks; always follow the vehicle maker’s service manual for exact procedures and alignment after replacement.

• Requires wheel removal, control arm access, and common hand tools
• Top off grease through supplied fittings after installation
• Perform wheel alignment immediately after replacement
• Inspect torque values and recheck fasteners after first few hundred miles

Who is this for: This A-Premium front ball joint kit is aimed at DIY mechanics and professional technicians restoring steering precision on compatible Ford Ranger and Mazda B-series pickups with front coil springs. It’s a practical upgrade for vehicles showing steering looseness, suspension noise, uneven tire wear, or drifting, and for anyone replacing both sides to maintain balanced handling and ride comfort.
