Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Visually inspect all suspension components for signs of wear, such as torn bushings or leaking shock absorbers.
3. If any components are damaged, remove them using a socket set and replace with new parts.
4. Torque new components to manufacturer specifications (check service manual for specific torque values).

3. Examine and Repair Exhaust System

Sub-steps:
1. Inspect the exhaust system for any loose mounts or damaged sections.
2. Tighten or replace any loose hangers or brackets as needed.
3. If a section of the exhaust is damaged, cut out the affected area and replace with a new exhaust pipe using exhaust clamps.

4. Check and Replace CV Joints or Axles

Sub-steps:
1. Remove the wheel and inspect the CV joint for any torn boots or grease leakage.
2. If damaged, remove the axle using a socket set and replace with a new axle.
3. Torque the axle nut to manufacturer specifications.

5. Inspect Wheel Bearings

Sub-steps:
1. Raise the front of the vehicle and spin the wheels by hand to check for roughness or play.
2. If a bearing is found to be faulty, remove the wheel hub assembly and replace the bearing using a press.
3. Reassemble and torque all fasteners to specifications.
