REMOVAL



1985-92

These models use two control arms on each rear wheel. To avoid the obvious confusion of referring to a "front rear control arm", they are referred to as No. 1 and No. 2, with arm No.1 being the closest to the front of the car.

No. 1 Arm
  1. Raise and safely support the vehicle.
  2.  
  3. Disconnect the sway bar link if so equipped.
  4.  
  5. Remove the bolt holding the arm to the body.
  6.  
  7. Remove the bolt holding the arm to the suspension knuckle.
  8.  
  9. Remove the arm.
  10.  

No. 2 Arm
  1. Raise and safely support the vehicle.
  2.  
  3. Observe and matchmark the position of the adjusting cam at the body mount.
  4.  
  5. Disconnect the bolt holding the arm to the suspension knuckle.
  6.  
  7. Disconnect the bolt holding the arm to the body.
  8.  
  9. Remove the arm.
  10.  
  11. Inspect the arms for any bending or cracking. If the arm is not true in all dimensions, it must be replaced. Any attempt to straighten a bent arm will damage it. Also check the bushings within the ends of the arms and replace any which are deformed or too spongy. If a bushing must be replaced, do not grease it before installation.

INSTALLATION



  1. Place the arm in position, install the arm to body bolts and partially tighten them. If installing arm No. 2, make sure the matchmarks for the adjusting cam are aligned.
  2.  
  3. Install the arm to the knuckle and partially tighten the bolts.
  4.  
  5. Reconnect the sway bar link if it was removed. Use a new nut and tighten it to 11 ft. lbs.

  7. Install the wheel.
  8.  
  9. Lower the car to the ground. Bounce the front and rear of the car several times to position the suspension.
