Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate type of power steering fluid if low.
Inspect the fluid for contamination (discoloration or debris) and replace if necessary.

3. Replace Power Steering Pump (if faulty)

Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid.
Disconnect the power steering fluid lines from the pump and drain fluid into the catch pan.
Remove the mounting bolts securing the power steering pump and take out the pump.
Install the new pump and tighten bolts to manufacturer specifications (typically 15-20 ft-lbs).
Reconnect the fluid lines, ensuring they are not cross-threaded.

4. Check and Replace Steering Gear (if binding)

Tools Required: Socket set, wrenches, power steering fluid.
Disconnect the tie rod ends from the steering gear.
Remove the bolts securing the steering gear to the chassis.
Replace with a new steering gear, ensuring it is aligned properly.
Reattach the tie rod ends and torque to manufacturer specifications (typically 30-35 ft-lbs).

5. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock several times to remove any air from the system.
Check the fluid level and top off as necessary.
