REMOVAL & INSTALLATION
Without Automatic Ride Control (ARC)
See Figures 1 and 2
- Raise the vehicle and position jackstands under the axle or wheel, in order to take the load off of the shock absorber.
- Remove the shock absorber lower retaining nut and bolt. Swing the lower end free of the mounting bracket on the axle housing.
- Remove the retaining nut(s) from the upper shock absorber mounting.
- Remove the shock absorber from the vehicle.
- Installation is the reverse of the removal procedure. Torque the lower shock absorber retaining bolt to 39-53 ft. lbs.
- On the Ranger torque the upper shock absorber mounting nut to 39-53 ft. lbs. On the Explorer/Mountaineer torque the upper shock absorber retaining nuts to 15-21 ft. lbs.
See Figure 6
- Place the vehicle in two wheel drive.
- Turn off the ARC control service switch.
- Raise the rear of the vehicle and place the jackstands under the rear axle assembly.
- Pry the rear shock absorber electrical connector retainer from the cross member then disconnect the plug.
- Disconnect the air line at the shock absorber by pushing in and holding the plastic ring while firmly pulling outward on the air line.
- Remove the lower shock absorber mounting nut and bolt assembly and swing the shock out of the bracket.
- Remove the two upper shock attaching nuts from the top of the crossmember then remove the shock.
- Installation is the reverse of the removal procedure. Tighten the upper attaching nuts to 15-21 ft. lbs. (21-29 Nm) and the lower attaching bolt to 39-53 ft. lbs. (53-72 Nm).
- Visually check the shock absorbers for the presence of fluid leakage. A thin film of fluid is acceptable. Anything more than that means that the shock absorber must be replaced.
- Disconnect the lower end of the shock absorber. Compress and extend the shock fully as fast as possible. If the action is not smooth in both directions, or there is no pressure resistance, replace the shock absorber. Shock absorbers should be replaced in pairs. In the case of relatively new shock absorbers, where one has failed, that one, alone, may be replaced.
