Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, screwdriver, pry bar, and a multimeter if electrical diagnostics are needed.
Safety Warnings: Ensure the vehicle is on a flat surface and secure with jack stands before working underneath it.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Use a dipstick or clean cloth to check the fluid level; if low, add the recommended power steering fluid.
Inspect the fluid for contamination; if dirty, consider flushing the system.

3. Inspect and Replace Worn Components

Steering Rack: If damaged, disconnect the steering column and the fluid lines, then remove the mounting bolts and replace the steering rack.
Tie Rod Ends: Use a socket to remove the nut, and use a tie rod puller to detach the tie rod from the steering knuckle; install the new tie rod and torque to specifications.
Wheel Bearings: Remove the wheel, brake caliper, and rotor; use a bearing puller to extract the old bearing and press in a new one, ensuring proper lubrication.
CV Joints: If damaged, remove the axle from the hub and transmission; replace the joint or the entire axle assembly as needed.
Brake Components: Inspect brake pads and rotors; replace any worn pads and resurface or replace rotors if necessary.

4. Reassemble and Torque All Components

Reinstall any removed components in reverse order, ensuring all nuts and bolts are torqued to the manufacturer's specifications.
