Tools Required: Socket set, wrench set, power steering fluid.
Remove the drive belt from the power steering pump:
- Loosen the tensioner and slide the belt off.
Disconnect the power steering lines from the pump:
- Use a wrench to unscrew the high-pressure and return lines.
Unbolt the power steering pump from the engine block and remove it.
Install the new power steering pump:
- Position the new pump and secure it with bolts to the engine block. Torque to manufacturer specifications.
Reconnect the power steering lines securely.
Reinstall the drive belt.

4. Inspect Steering Rack and Linkage

Visually examine the steering rack and linkage for any visible damage or excessive wear.
If issues are found, replace the steering rack or linkage components as necessary.

5. Reassemble and Test

Reconnect the battery.
Start the vehicle and turn the steering wheel from lock to lock to bleed air from the system.
Check for leaks around the power steering pump and lines.
