The role of steering gear

A power "steering rack" or "steering gear" is a rack gear and a pinion gear that transmits the steering wheel rotation inside of your car to tire movement outside of your car. Most modern steering racks have either a hydraulic pump for assist or electric motor for assist. The rack is connected to the outer steering mechanisms with tie rod ends.

• It converts the rotational motion of the steering wheel into the linear motion needed to turn the wheels.
• It provides a gear reduction, making it easier to turn the wheels.

Replace the Steering Rack

1. Put the wheels in a straight-ahead position. The steering wheel should be in the center position. Remove the key from the ignition and make sure the steering wheel is locked You do not want the steering wheel to turn while removing the rack. Doing so will make it possible for the spiral cable in the steering wheel to unwind and become useless.
2. Crack loose all the wheel lug nuts
3. Raise and support the vehicle with approved jack stands.
4. Remove both front wheels.
5. Remove the Steering Shaft Coupler Outer Seal and unbolt the upper pinch bolt on the Steering Shaft Coupler assembly.
6. Detach the outer tie rod ends. You may need to use a special tie rod end puller to get them off. You can rent one at the local rental store. Most times a sharp rap with a BFH on the end of the tie rod mount will shock it loose. Do not hit the tie rod end itself.
7. Remove any parts required to gain access to the rack mounting bolts, lines and steering coupling.
8. Depending on accessibility, at this point, you can remove the power steering rack mounting bolts, or crack the power steering high pressure and return lines.
9. Depending on accessibility, at this point, you can remove the power steering rack mounting bolts, or crack the power steering high pressure and return lines. It may be easier to get a wrench to swing on a power steering line fitting once you've unbolted the rack and moved it a bit. Also, reattaching the lines may be easier before the new rack is bolted in place.
10. Place a drain pan under the vehicle and remove the hydraulic power steering pressure hose and power steering return hose from the power steering rack.
11. Now comes the fun part, twist and turn and jiggle it out through one of the wheel well openings. Make sure the kids are in the house because certain words will be necessary to coax the rack out and they are not words little ears should hear. 
12. If the new rack has new tie rod ends, measure the overall length of the old rack and tie rod assembly. Set the overall length of the new assembly to this same dimension by twisting the tie rod ends on their threads. Keep the rack centered and split the overlap difference between the left and right rod ends as you do this, or the steering wheel will be off-center when you're done.
13. If you are reusing the old tie rod ends, crack the lock nuts loose. Count how many full turns it takes to remove the tie rod ends. Center the new rack and install tie rod ends the same number of turns on the new rack. Again, check the overall length and split the difference.
14. Install the new rack using the same words you used to get it out.
15. Reconnect the power steering lines, using new "O" rings, if required. Usually, the high-pressure line uses a slightly larger "O" ring so be careful not to mix them up.
16. Reconnect the Steering Shaft Coupler assembly and bolt the rack back into place.
17. Reattach the tie rod ends to the steering knuckles. Use new cotter pins for the castellated nuts; never reuse the old cotter pins.
18. Put the wheels back on and torque the lug nuts to specifications.
19. Remove the return line from the power steering pump and place the end into a bucket.
20. Fill the power steering pump and start the engine until clean fluid comes out of the return hose. You may be able to install an inline filter in the return line to protect the new rack. I have known guys who have used fuel filters for this purpose.
21. Have the front end aligned to reset the toe-in adjustment to specification or the vehicle will handle poorly and wear out the tire quickly.
