Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift the front using a jack and jack stands.
Disconnect the battery to prevent any electrical issues.

2. Fluid Inspection and Replacement

Tools Required: Fluid pump, funnel, rags
Check the power steering fluid reservoir for level and condition.
If fluid is low or contaminated:
- Drain old fluid from the reservoir.
- Refill with manufacturer-recommended power steering fluid.
- Start the engine and turn the wheel from lock to lock to purge air and check for leaks.

3. Steering and Suspension Inspection

Tools Required: Socket set, torque wrench, pry bar
Visually inspect the steering rack and tie rod ends for any signs of wear or damage.
Use a pry bar to check for play in suspension components.
Replace any damaged components:
- To replace tie rod ends, remove the cotter pin, nut, and use a tie rod puller to detach.
- Install new tie rod ends and torque to manufacturer's specifications.

4. Reassembly and Reinstallation

Ensure all components and connections are secure and torqued to specifications.
Reconnect battery and lower the vehicle.
Check alignment if any components were replaced.
