8. Siphon the power steering fluid from the reservoir to prevent excessive spillage.
9. Remove the power steering fluid reservoir bracket bolt.
10. Remove the power steering fluid reservoir.
11. Siphon the brake fluid from the reservoir to minimize spillage.
12. Remove the brake booster vacuum connection from the intake plenum.
13. Remove the brake pipes from the master cylinder.
14. Remove the electrical connector from the master cylinder reservoir cap.
15. Remove the sound insulator tabs.
16. Remove the sound insulator.
17. Match-mark the lower steering coupler with splines on the steering gear, if the same gear is to be reinstalled.
    
    WARNING

    Do not allow the steering wheel to rotate when the steering gear coupler is disconnected or damage to the SIR coil inside the steering column will result.
18. Remove the steering coupler bolts (1) from the coupler. 
    
    NOTE

    After the key is removed, a substantial range of steering wheel travel is possible before the locking mechanism will set, therefore, it is necessary to lock the steering wheel with a locking device.

19. Place the steering wheel in the straight ahead position.
20. Lock the steering wheel in place with the appropriate device.
21. Remove the key from the ignition.
22. Carefully spread the clamp open to allow the shaft to be moved upward and out of the way of the steering gear connection.
23. Perform the following steps to remove the brake pedal from the brake power booster link rod:
    1. Remove the retaining clip from the pin.
    2. Drive the pin out of the linkage rod.
    3. Remove the I/P driver knee bolster energy absorber.
    4. Remove the fuse.
    5. Remove the relay panel screws.
24. Position the panels out of the way to enable easier access to the upper brake vacuum booster nuts.
25. Remove the vacuum booster nuts from the inward side of cowl.
26. Remove the vacuum booster with the master cylinder attached.
27. Remove the A/C evaporator line extension quick connect.
28. Remove the power steering hoses (2) from the steering gear. The repositioning of the power steering hoses aids in the EBTCM/BPMV assembly removal.
29. Remove the Electronic Brake Control Module (EBCM) assembly.

39. Remove the upper steering gear bolt and shim(s). Note the position of the shim(s) for reinstallation.
40. Remove the steering gear.

To install:

1. Center the steering gear, as follows:
   1. Rotate the stub shaft from stop to stop with an ⁵ / ₁₆ inch (8 mm) open-end wrench counting the number of turns before installing on the vehicle.
   2. Starting at either stop, turn the stub shaft back ¹ / ₂ the total number of turns.
   3. Align the mark on the stub shaft to V mark on the steering gear case. This is the center of the gear.
