CAUTION:
  • The rotation of the spiral cable (SRS "Air bag" component part) is limited. If the steering gear must be removed, set the front wheels in the straight-ahead direction. Do not rotate the steering column while the steering gear is removed.
  • Remove the steering wheel before removing the steering lower joint to avoid damaging the SRS spiral cable. See DRIVER-SIDE AIR BAG MODULE & SPIRAL CABLE .
  1. Detach tie-rod outer sockets.

    • Observe specified tightening torque when tightening high-pressure and low-pressure line connectors. Excessive tightening will damage threads of connector or O-ring.

      Connector tightening torque: 

      1. 1 Low-pressure side: 28 - 39 N.m (2.8 - 4.0 kg-m, 21 - 28 ft-lb) 
      2. 2 High-pressure side: 15 - 25 N.m (1.5 - 2.5 kg-m, 11 - 18 ft-lb) 

    • The O-ring in low-pressure pipe connector is larger than that in high-pressure connector. Take care to install the proper O-ring.
      • CAUTION: Tightening torque must not exceed 49 N.m (5 kg-m, 36 ft-lb).

    • Initially, tighten nut on tie-rod outer socket and knuckle arm to 29 to 39 N.m (3 to 4 kg-m, 22 to 28 ft-lb). Then tighten further to align nut groove with first pin hole so that cotter pin can be installed.
    • Before removing lower joint from gear, set gear in neutral (wheels in straight-ahead position). After removing lower joint, put matching mark on pinion shaft and pinion housing to record neutral position.
    • To install, set left and right dust boots to equal deflection. Attach lower joint by aligning matching marks of pinion shaft and pinion housing.
