Removal & Installation

Print

  1. Raise and safely support the vehicle, allowing the front suspension to hang freely.
  2.  
  3. Remove both front tire and wheel assemblies.
  4.  


CAUTION
Failure to disconnect the intermediate shaft from the rack and pinion stub shaft can result in damage to the steering gear and/or intermediate shaft. This damage may cause a loss of steering control and possibly, personal injury.

The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which will damage the coil.

  1. If equipped, move the intermediate shaft cover upward, then unfasten the intermediate shaft-to-stub shaft pinch bolt.
  2.  
  3. Using a suitable puller, separate both tie rod ends from the steering knuckles.
  4.  
  5. Position a suitable drain pan under the power steering fluid lines. Remove the power steering fluid line retainer, then disconnect the outlet and inlet hoses from the steering gear. Allow the fluid to drain, then plug the lines to avoid contaminating the system.
