Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, flathead screwdriver, torque wrench, power steering fluid.
Ensure the vehicle is on a flat surface and secure it with jack stands after lifting.
Disconnect the negative battery terminal to prevent electrical issues during repair.

2. Remove Steering Rack

Drain Power Steering Fluid: Place a drain pan under the steering rack and remove the drain plug to collect fluid.
Detach Steering Column: Remove the steering column cover and unbolt the universal joint connecting the steering column to the rack.
Disconnect Tie Rods: Use a tie rod puller to separate the tie rods from the steering rack.
Unbolt Steering Rack: Remove the bolts securing the steering rack to the subframe and carefully slide it out of position.

3. Inspect and Replace Components

Inspect Steering Rack: Check for internal wear or damage inside the rack. If damaged, replace the steering rack.
Replace Seals: If the steering rack is in good condition but leaking, replace the seals and O-rings.
Install New or Repaired Rack: Position the new or repaired rack back into the subframe and secure it with bolts, torquing them to manufacturer's specifications (typically around 25-30 ft-lbs).

4. Reattach Components

Reconnect Tie Rods: Ensure tie rods are properly aligned and tightened to manufacturer specifications.
Reattach Steering Column: Reconnect the universal joint to the steering column and secure it.
Refill Power Steering Fluid: Fill the power steering reservoir with the appropriate type of fluid (check owner’s manual for specifications).

5. Final Checks

Bleed Power Steering System: Turn the steering wheel from lock to lock several times with the engine running to eliminate air from the system.
Reconnect Battery: Reattach the negative battery terminal.
