Fig. Fig. 5: Measuring the power assist effort with a spring scale

Turning the steering wheel from lock-to-lock several times will warm up the fluid. Effort should be no more than 4 lbs. (1.8 kg) for 1988-91 models, or 3.3 lbs. (1.5 kg) for 1992-95 models when measured with a spring scale attached to the steering wheel.

REMOVAL & INSTALLATION



  1. Disconnect the negative battery cable. Raise the vehicle and support it safely.
  2.  
  3. Remove the cover panel and steering joint cover. Unbolt and separate the steering shaft at the coupling.
  4.  
  5. Drain the power steering fluid by disconnecting the return hose at the box and running the engine while turning the steering wheel lock-to-lock until fluid stops draining. Remove the gearbox shield, if equipped. Remove the front wheels.
  6.  
  7. Remove the cotter pins and unscrew the castle nuts on the tie rod ends. Using a ball joint tool, disconnect the tie rod ends. Lift the tie rod ends out of the steering knuckles.
  8.  
  9. If equipped with manual transaxle, disconnect the shift lever torque rod from the clutch housing. Slide the pin retainer out of the way, drive out the spring pin and disconnect the shift rod.
  10.  
  11. If equipped with automatic transaxle, remove the shift cable guide from the floor and pull the shift cable down by hand.
  12.  
  13. Remove the two nuts connecting the exhaust header pipe to the exhaust pipe and remove the exhaust header pipe (called exhaust pipe A for 1992-95 models). Disconnect the three hydraulic lines from the control unit.
  14.  
  15. Slide the tie rod ends all the way to the right and remove the steering rack mounting bolts.
  16.  
  17. Drop the gearbox far enough to permit the end of the pinion shaft to come out of the hole in the frame channel, then rotate it forward until the shaft is pointing rearward.
  18.  
  19. Slide the gearbox to the right until the left tie rod clears the beam, then drop it down and out of the vehicle to the left.
  20.  

To install:
  1. Install the gearbox and tighten the bracket bolts to 29 ft. lbs. (40 Nm). If equipped with a manual transaxle, reinstall the pin retainer after driving in the pin and be sure the projection on the pin retainer is in the hole.
  2.  
  3. Reconnect the fluid lines and tighten the line from the pump to 28 ft. lbs. (38 Nm), the line to the reservoir to 9 ft. lbs. (13 Nm) and the line to the oil cooler to 20 ft. lbs. (29 Nm).
  4.  
  5. Reconnect the tie rod ends and tighten to the proper specification.
  6.
