Coil Springs: Removal
- Raise and support vehicle under frame, with control arms hanging free. Remove wheel and tire assembly. Disconnect shock absorber and stabilizer bar at lower control arm. Install Lower Control Arm Shaft Support (J-23028-01
) on a jack. See Figure. Position assembly under lower control arm so shaft seats in grooves of lower control arm shaft support.WARNING: Securely bolt Lower Control Arm Shaft Support (J-23028-01 ) to jack, and install safety chain through lower control arm and coil spring to prevent personal injury.
- If air bags are installed in coil springs, remove valve cap and valve core. Pry on air cylinder to release air pressure. Reinstall valve core and valve cap to retain vacuum condition. Push air cylinder upward as far as possible. Install safety chain around coil spring and through lower control arm.
- Raise jack to release tension from lower control arm shaft. Remove control arm shaft-to-crossmember "U" bolts. Carefully lower jack until all tension is released from coil spring. Remove safety chain and coil spring. Remove air cylinder.
- Check air cylinder for leaks. Inflate air cylinder to 20 psi (1.4 kg/cm2 ) and submerge in water. Check for air bubbles. Replace air cylinder if leaks exist.
