Control Valve Adjustment (1970-71)
- Adjustment should be performed with full fuel tank and the equivalent of a three passenger load. Raise vehicle and support front and rear wheels.
- Disconnect shock absorber line from height control valve and connect test gauge to end of line. Attach air pressure source to test gauge and maintain 8-15 psi pressure in shock absorbers. Jounce vehicle to equalize rear suspension.
- Loosen overtravel lever adjusting nut and lower valve arm until air escapes from exhaust port. Slowly move valve arm up until air bleed stops, then tighten adjusting nut. Remove test gauge and air supply, reconnect line to control valve.
