Suspension Control Arm Bushing for Rear Knuckle Applications

Mevotech GK8588 is a suspension control arm bushing built for rear at knuckle upper locations on select Ford, Lincoln, and Mercury vehicles. It uses natural rubber construction to support suspension articulation while helping maintain a stable, quiet ride.

  • Natural rubber material for OE-style compliance and vibration isolation
  • Black finish with a 0.52 wall thickness
  • Inside diameter: 0.57; outside diameter: 1.61; length: 2.64
  • Designed for rear at knuckle (upper) suspension positions
  • Fits Ford Thunderbird, Mercury Cougar, and Lincoln Mark VIII applications
  • Mevotech GK8588 and Mevotech Original Grade GK8588 cross-reference for the same application

Detailed Product Overview

This suspension control arm bushing is intended for rear knuckle upper mounting points on 1989-1997 Ford Thunderbird, 1989-1997 Mercury Cougar, and 1993-1998 Lincoln Mark VIII models. The natural rubber construction helps preserve suspension geometry at the control arm pivot point while reducing harshness transmitted through the chassis. Mevotech GK8588 is a direct-fit service part for vehicles that need a replacement bushing with the listed dimensions and position-specific fitment.

This part cross-references MOOG Chassis Products K8588 and Bosch 17092 for the same application.

Common Repair Uses

  • Restoring worn rear suspension pivot support
  • Addressing looseness or play at the rear knuckle upper control arm area
  • Reducing clunks, squeaks, or vibration from deteriorated rubber bushings
  • Correcting suspension movement caused by cracked or compressed bushing material
  • Maintaining alignment stability in Thunderbird, Cougar, and Mark VIII rear suspension service

Installation Notes and Tips

Verify the rear at knuckle (upper) position before installation and compare the bushing dimensions to the removed part. Proper pressing tools are typically required for control arm bushing service, and the control arm should be inspected for wear, corrosion, or damage before reassembly. Confirm vehicle application by year, make, model, and suspension position for 1989-1997 Ford Thunderbird, 1989-1997 Mercury Cougar, and 1993-1998 Lincoln Mark VIII.

Quality Assurance

Mevotech GK8588 is built as a suspension service component with natural rubber construction and application-specific dimensions for the listed vehicles. Mevotech Original Grade GK8588 and GK8588 are referenced for the same fitment, supporting accurate parts matching during suspension repair.
