Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joints for torn boots or excessive play.
4. If damaged, remove the axle nut and detach the CV joint from the wheel hub.
5. Replace the CV joint with a new unit, ensuring to use appropriate torque (typically around 250 Nm for the axle nut).
6. Reinstall the wheel and lower the vehicle.

3. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level.
3. If low, add manufacturer-recommended power steering fluid to the appropriate level.
4. Start the engine and turn the steering wheel to bleed any air from the system.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect all suspension components for cracks or signs of wear.
2. Replace any worn or damaged components, such as strut mounts or control arm bushings.
3. Ensure all nuts and bolts are torqued to manufacturer specifications.

5. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Grab the wheel at the 12 and 6 o'clock positions and shake it to check for play.
3. If play is detected, remove the wheel and inspect the wheel bearing.
4. Replace any worn wheel bearings according to manufacturer specifications.

6. Inspect Steering Rack and Tie Rod Ends

Sub-steps:
1. Check tie rod ends for any movement or looseness.
2. If any play is present, remove the tie rod end using a tie rod puller.
3. Replace with a new tie rod end and torque to specification.
4. Inspect the steering rack for leaks or damage, replacing if necessary.
