Disconnect the negative battery terminal to prevent electrical issues.

Tools Required:

Socket set
Torque wrench
Steering wheel puller (if necessary)
Pliers

OBD-II scanner (for diagnostics)

2. Remove the Old Steering Rack

Lift the Vehicle:
- Use a hydraulic lift or jack stands to elevate the front of the vehicle.
Remove Front Wheels:
- Use a socket set to remove the lug nuts and take off the front wheels.
Disconnect Steering Components:
- Remove the cotter pins from the tie rod ends and use a puller to detach the tie rods from the steering rack.
Drain Power Steering Fluid:
- Position a catch pan under the steering rack and disconnect the fluid lines. Allow the fluid to fully drain.
Unbolt Steering Rack:
- Locate the mounting bolts securing the steering rack to the subframe. Use a socket set to remove these bolts.
Remove the Steering Rack:
- Carefully remove the steering rack from the vehicle. Ensure that no components are damaged during removal.

3. Install the New Steering Rack

Position New Steering Rack:
- Align the new steering rack in place, ensuring it fits into the mounting points.
Bolt the Steering Rack:
- Secure the steering rack with the mounting bolts you previously removed. Torque to manufacturer specifications (typically around 30-35 lb-ft, but verify with service manual).
Reconnect Steering Components:
- Reattach the tie rods to the new steering rack, using new cotter pins if necessary.
Reconnect Fluid Lines:
- Attach the power steering fluid lines to the new rack, ensuring they are secure to prevent leaks.

4. Refill and Bleed Power Steering System

Refill Power Steering Fluid:
- Fill the power steering reservoir with the appropriate fluid type (typically Mercon ATF for Ford).
Bleed the System:
- Start the engine and turn the steering wheel from lock to lock several times while monitoring the fluid level. Add fluid as necessary to remove air from the system.

5. Reassemble Vehicle

Reattach Front Wheels:
- Put the wheels back on and tighten the lug nuts to the specified torque (usually 100-120 lb-ft).
Lower Vehicle:
- Carefully lower the vehicle back to the ground.
Reconnect Battery:
- Reconnect the negative battery terminal.
