Original Rack Removal
Note: For vehicles with airbags disconnect the negative battery cable and the positive. Wait 2 minutes before
proceeding. This is to avoid any accidental deployment of the airbags.
Note: We recommend the use of new outer tie rod ends and mounting bushings when installing this product to
obtain the proper performance.
Note: A front end alignment is necessary after installation.
1) Position the front wheels straight ahead and the lock the steering column in place.
2) Raise your vehicle and ensure that it is properly supported.
3) Disconnect your power steering lines from the rack and pinion and cap the ends to make sure that no
contamination gets into the lines.
4) Remove the pinch bolt that retains the rag joint to the rack and pinion.
5) Remove the cotter pins and castle nuts from the outer tie rod ends and then remove the outer tie rod ends
from the spindles.(A tie rod end puller or pickle fork may be necessary.)
6) Next remove the nuts and bolts that mount the rack to the cross member.
7) As you lower the steering gear separate the steering shaft from the input shaft of the steering gear.
8) Remove the bolt that retains the steering shaft to the column and remove the steering shaft from the car.
