Solution

1. Preparation

Gather tools and parts required for repairs.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels for better access to suspension components.
3. Inspect control arms and bushings for cracks or deterioration. Replace if necessary.
4. Check strut assemblies for leaks or damage. Replace as needed with OEM parts.
5. Reassemble the suspension, ensuring all bolts are torqued to the manufacturer specifications.

3. Check and Replace Wheel Bearings

Sub-steps:
1. Spin the wheel hub by hand; listen for any grinding or roughness indicating bad bearings.
2. If necessary, remove the wheel hub assembly using a socket set.
3. Replace the wheel bearing with a new one, applying proper grease and ensuring correct orientation.
4. Reinstall the wheel hub, torquing the retaining nut to the specified value.

4. Inspect and Repair Exhaust System

Sub-steps:
1. Visually inspect the exhaust system from the manifold to the tailpipe for any loose or damaged components.
2. Tighten any loose bolts or clamps found during inspection.
3. Replace any damaged sections of the exhaust, using appropriate gaskets for sealing.

5. Examine and Repair CV Joints and Axle Shafts

Sub-steps:
1. Inspect the CV joints for torn boots or excessive play.
