REMOVAL & INSTALLATION



1964-1972 Vehicles
  1. Raise and support the vehicles safely using jackstands under the frame.
  2.  
  3. Position a hydraulic jack under the axle and support it.
  4.  
  5. Disconnect the shock absorber at the bottom on the side where the spring is being replaced.
  6.  
  7. Slowly lower the axle to the bottom of its travel (making sure no brake lines or cables are being stretched), then carefully pry the lower end of the spring over the axle retainer.
  8.  
  9. Remove the spring and its insulator from the vehicle.
  10.  

On 1964-66 cars, the spring retainer must be removed to remove the spring. It is fastened to the housing with a nut and bolt.

To install:
  1. Install the spring into the frame seat with its rubber insulation.
  2.  
  3. Carefully pry the spring into the axle housing retainer. Install the retainer on 1964-66 vehicles and torque the bolt to 45-55 ft. lbs. (61-75 Nm).
  4.  
  5. Slowly raise the axle into position and install the shock absorber. While holding the stud hex, tighten the shock absorber lower nut to 60 ft. lbs. (81 Nm).
  6.  
  7. Remove the jackstands, then carefully lower the vehicle.
  8.  

1973 and Later Vehicle
  1. Raise and support the vehicles safely using jackstands under the frame.
  2.  
  3. Position a hydraulic jack under the axle and support it.
  4.  
  5. Disconnect the shock absorber at the bottom on the side where the spring is being replaced.
  6.  
  7. Remove the brake hose support bolt or junction block retaining bolt, then support the brake hose aside to allow the axle to drop. For most vehicles, this should provide the necessary clearance to lower the rear axle. However, if this is not sufficient, DO NOT allow brake lines to be stretched or bent as they will be damaged. If necessary, disconnect the brake hydraulic line at the junction block located on the axle housing.
  8.  
  9. Disconnect the upper control arm at the axle.
  10.  

Note the direction which the spring ends are pointing for installation purposes.

  1. Slowly lower the axle to the bottom of its travel, then carefully pry the lower end of the spring over the axle retainer and remove the spring along with its insulator.
  2.  

To install:
  1. Install the spring in its frame seat along with its rubber insulator.
  2.  
  3. Carefully pry the lower end of the spring over the vertical flange of the axle bracket spring seat.
  4.  
  5. Position the spring so that the coil end is pointing in the direction noted during removal. For most applications, the upper coil points toward the right side of the car.
  6.  
  7. Raise the axle and connect the lower shock absorber mount. While holding the stud hex, tighten the shock absorber lower nut to 60 ft. lbs. (81 Nm).
  8.  
  9. Connect the upper control arm to the axle housing.
  10.  
  11. Secure the brake lines to the axle using the support or junction block bolt, as applicable. If any lines were disconnected, fasten them, then properly bleed the hydraulic brake system.
