Power-assisted steering box: Removal - Refitting

JH3 or JR5, and LEFT-HAND DRIVE

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Position the vehicle on a two-post lift (see Vehicle: Towing and lifting) (MR 392, 02A, Lifting equipment).
• Remove:
  • the front wheels (see 35A, Wheels and tyres, Wheel: Removal - Refitting, 35A-1),
  • the engine undertray.

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Lift the floor carpet to access the universal joint bolt.

• Remove the universal joint cover (1) (do not keep).
• Set the wheels straight ahead.

• Remove the universal joint bolt (2) (do not keep),
• Remove the universal joint from the steering box.

• Remove:
  • the mounting nuts (3) from the track rod,
  • the anti-roll bar tie-bar upper nuts (4).

Note: It is necessary to rotate the anti-roll bar onto itself in order to make it easier to position the steering rack on the sub-frame cross member.

• Extract the ball joint using (1) Tav. 476.
• Tilt the anti-roll bar towards the rear of the vehicle.
• Unclip the oxygen sensor wiring harness from the steering rack.

• Remove the steering box mountings (5).

• Remove the engine tie-bar mounting (6) on the engine.
• Loosen the engine tie-bar retaining bracket mounting bolt (7) in order to be able to turn the retaining bracket.
• Tip the engine forwards using a lever to remove the steering rack.

• Remove the exhaust downpipe mounting bolts (8), if necessary.
• Remove the steering rack, going towards the left-hand side of the vehicle; two people are required to carry out this operation.

  If the vehicle is fitted with xenon bulbs, be careful not to damage the xenon bulb sensor.

REFITTING

I - REFITTING PREPARATION OPERATION

• Always replace the following after each removal operation:
  • the universal joint nut and bolt,
  • the anti-roll bar link rod brake nuts.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the steering rack inserting it from the left-hand side of the vehicle, being careful not to damage the xenon bulb beam sensor,
  • the xenon bulb beam sensor (if fitted to the vehicle),
  • the steering rack mounting bolts.
• Torque tighten the steering box mounting bolts (110 N.m), starting with the bolt on the right-hand side of the vehicle.
• Refit the engine tie-bar mountings.
• Torque tighten the engine tie-bar mounting bolt (105 N.m).
• Refit the exhaust downpipe mounting bolts, if they were removed.

• Respect the direction when fitting the universal joint nut and bolt.
• Refit:
  • the universal joint,
  • the new universal joint bolt,
  • the new universal joint nut.
• Pre-tighten the universal joint nut and bolt.
• Pull the intermediate shaft to make sure that the bolt is present in the neck.
• Tighten to torque:
  • the exhaust downpipe mounting bolts (21 N.m),
  • the universal joint mounting bolt (24 N.m).
• Refit the floor carpet.

Note: Check that the floor carpet fits under the accelerator pedal end-stop.

• Clip the oxygen sensor wiring harness back onto the steering rack.
• Tilt the anti-roll bar back into its original position.
• Place the ball joints back into their housing.
• Refit:
  • the track rod mounting nuts,
  • the anti-roll bar link rod lower nuts.
• Tighten to torque:
  • the anti-roll bar tie-rod nuts (44 N.m),
  • the track rod nuts (35 N.m).

III - FINAL OPERATION

• Refit:
  • the engine undertray,
  • the front wheels (see 35A, Wheels and tyres, Wheel: Removal - Refitting, 35A-1).
• Adjust the front axle assemblies (see Adjusting the front axle system).
• Be sure to initialise the xenon bulb system (if fitted to the vehicle); (see MR 394 Fault finding, 80C, Discharge bulbs, Replacement of components).

DP0 or TL4, and LEFT-HAND DRIVE

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Put the vehicle on a two-post lift (see Vehicle: Towing and lifting).
• Remove:
  • the front wheels (see 35A, Wheels and tyres, Wheel: Removal - Refitting, 35A-1),
  • the sub-frame (see 31A, Front axle components, Front axle subframe: Removal - Refitting, 31A-55).

REFITTING

I - REFITTING PREPARATION OPERATION

• Always replace the following after each removal operation:
  • the anti-roll bar link rod brake nuts,
  • the universal joint bolt and cam nut.

WARNING

Be sure to insert a 10 mm shim between the radiator cross member and the sub-frame, and centre the radiator cross member pin in the subframe opening on the lower arm front mounting, to torque tighten the radiator cross member mountings.

• Set the wheels straight ahead.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the steering rack,
  • the xenon bulb beam sensor (if fitted to the vehicle),
  • the steering rack mounting bolts.
• Tighten to torque the steering rack mounting bolts (110 Nm).

III - FINAL OPERATION
