  1. Installation is the reverse of removal. Tighten the nuts linking the bar to the suspension arm until 0.24 in. (6mm) of bare thread is exposed. Torque the machine screws which fasten the U-shaped clip and bushing to the body to 32-39 ft. lbs. for 1983-87 626s, 27-40 ft. lbs. for 1988-89 626/MX-6s and 37-45 ft. lbs. for 929s. Also, when assembling the U-shaped rubber bushings to the bar, align the bushing with the line on the bar and install it so the slit faces the rear of the car. On 929s, this line is yellow. Tighten the locknuts on top of the bolt linking the sway bar to the steering knuckle until 0.98 in. (25mm) of bare thread is exposed for 1983-87 626s, 0.71-0.91 in. (18-23mm) for 1988-89 626/MX-6s and 0.59 (15mm) for 929s.

  2.  
  3. Remove the two locknuts, washers, bushings, bolt and spacer that link the stabilizer bar to the lower arm. Keep the parts in order.
  4.  
  5. Remove the nuts, washers, rubber bushings and bracket holding the stabilizer bar to frame and remove the stabilizer bar.
  6.  
  7. Inspect the stabilizer bar for damage such as bends, cracks, or metal deterioration. Inspect the bushings for signs of wear or deterioration and replace as necessary.
  8.  
  9. To install, mount the bushings so that the seam faces the rear of the chassis.
  10.  
  11. Mount the bracket side of the stabilizer first and temporarily tighten it. After mounting the control link side, tighten to the specified torque with the vehicle in the unloaded condition.
  12.  
  13. Tighten the stabilizer bar bushing and bracket bolts to 23-34 ft. lbs. (31-46 Nm).
  14.  
  15. On 1986-87 323s, tighten the bushing to control arm nut so that there is 0.43 in. (11mm) of thread exposed at the top of the control link. On 1988-89 models, the control link stud has two sets of nuts on each side. Torque each top nut to 9-13 ft. lbs.
