WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1990 GMC Suburban, 1990 GMC Pickup, 1990 GMC Cab & Chassis, 1990 Chevrolet Suburban, and 1990 Chevrolet Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. Bushings and control arm shaft can be replaced without removing control arm. Raise and support vehicle under frame with control arms hanging free.
  2. Remove wheel and tire assembly. Disconnect shock absorber and stabilizer bar bracket at lower control arm. Install Lower Control Arm Shaft Support (J-23028-01 ) onto a suitable jack. Position assembly under lower control arm so that shaft seats in grooves of lower control arm shaft support. See Figure .
    WARNING: Lower Control Arm Shaft Support (J-23028-01 ) must be securely bolted to jack and safety chain must be installed through lower control arm and coil spring to prevent personal injury.
  3. Remove control arm shaft-to-crossmember "U" bolts. Loosen control arm shaft bushing nuts. DO NOT remove nuts. Remove control arm-to-frame "U" bolts. Carefully lower jack until all spring tension is released. Remove nuts and "U" bolts. Lower control arm from frame.
  4. Remove stake area from front bushing. Use Control Arm Bushing Set (J-24435-A ) for bushing replacement. Using Spacer (J-24435-6 ), Bushing Remover (J-24435-2 ) and "C" Clamp (J-24435-7 ), remove one bushing from control arm. With control arm shaft still in control arm, remove remaining bushing from control arm.
  5. To install, reverse removal procedure. Using Remover/Installer (J-24435-4 ), Spacer (J-24435-6 ) and "C" Clamp (J-24435-7 ), install one bushing. Install lower control arm shaft and install remaining bushing. See Figure . Stake front control arm bushing in at least 2 areas on control arm.
  6. Install lower control arm. Ensure front indexing hole in lower control arm shaft aligns with crossmember attaching stud. Tighten all fasteners to specification. See TORQUE SPECIFICATIONS  table at the end of this article. Check wheel alignment. See ALIGNMENT SPECIFICATIONS article.
