Detailed Description

MAS Chassis CB8710 is designed to replace the original equipment control arm and ball joint assembly on specific Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Ford Explorer Sport, Mazda B2500, Mazda B3000, Mazda B4000, and Mercury Mountaineer front right upper applications. The forged/cast steel arm is paired with an installed ball joint and service grease fitting to support consistent suspension articulation and steering feel. Its adjustable construction helps match the OE configuration used on these vehicles, while the included mounting hardware supports a proper installation.

This part number, CB8710, is built around the original suspension geometry for vehicles that use a two-piece design in the front right upper location. The assembly is intended to help maintain smooth ride quality, directional stability, and predictable handling characteristics after wear-related suspension service.

What It Helps Address

  • Clunking or looseness from a worn upper control arm assembly
  • Uneven steering response caused by ball joint wear
  • Front-end instability during braking or lane changes
  • Suspension noise from deteriorated control arm components
  • Alignment issues related to worn upper suspension hardware

Installation Notes and Tips

Install CB8710 in the front right upper position only on the listed applications. Verify the vehicle’s two-piece design, mounting hole diameter, and ball joint stud style before installation. Because this assembly is adjustable, a professional wheel alignment should be performed after replacement. Inspect adjacent suspension components, including the lower control arm, tie rods, and steering linkage, to confirm the source of wear.

Quality Assurance

MAS Chassis uses an industry-focused evaluation process for this suspension control arm and ball joint assembly to support OE-style ride control, directional stability, and predictable suspension dynamics. Part number CB8710 is built as a direct replacement for the specified applications and is engineered to meet the demands of everyday driving.
