Detailed Description

Mevotech GK8158 is a steering idler arm designed for 1967-1970 Ford Mustang and 1967-1970 Mercury Cougar front steering systems. It uses a bushing attachment type and includes the washer, castle nut, and cotter pin specified in the product data. The corrosion-resistant finish helps protect the component in undercar conditions, while the OE-replacement design supports proper steering linkage geometry for these classic vehicles. This part cross-references MOOG Chassis Products K8158 for the same application.

What It Helps Address

  • Loose or wandering steering feel in a Ford Mustang or Mercury Cougar
  • Excessive play in the front steering linkage
  • Wear-related steering response issues from an aging idler arm
  • Corrosion on the original steering component
  • Restoration work requiring a direct-fit steering idler arm replacement

Installation Notes and Tips

Verify front steering fitment before installation on 1967-1970 Ford Mustang and 1967-1970 Mercury Cougar models. Inspect related steering linkage parts for wear, and confirm the bushing attachment point, washer, castle nut, and cotter pin are seated correctly during assembly. After installation, check steering alignment and road-test the vehicle to confirm proper operation.
