Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Worn Components

A. Ball Joints and Tie Rod Ends

Tools Required: Socket set, torque wrench, ball joint separator
Steps:
1. Remove the wheel from the affected side to access the suspension components.
2. Use a ball joint separator to detach the ball joint from the control arm.
3. Remove the tie rod end from the steering knuckle using a wrench.
4. Inspect both components for wear; replace them if damaged.
5. Reinstall new parts and torque to manufacturer specifications (typically around 40-60 ft-lbs for tie rods).

B. Brake Inspection

Tools Required: Brake caliper tool, socket set
Steps:
1. Inspect the brake pads for wear; replace if they are less than 3mm thick.
2. Check the caliper for any loose bolts or signs of damage.
3. Clean the brake components to ensure smooth operation.
4. Reassemble the brake system and ensure all fasteners are torqued to specifications.

3. Power Steering Check

Tools Required: Power steering fluid, funnel
Steps:
1. Check the power steering fluid level; top off if low.
2. Inspect the power steering pump for leaks.
3. If leaks are found, replace the power steering pump as necessary.

4. Reassemble and Lower Vehicle

Steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Carefully lower the vehicle back to the ground.
3. Torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).
