Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack and jack stands to safely elevate the vehicle.
- Remove the front or rear wheels as needed for access.
Check Control Arms and Bushings:
- Inspect control arms for cracks or bends.
- Look at bushings for signs of wear or deterioration.
- If damaged, replace with OEM parts.
Examine Struts and Shocks:
- Check for leaks or physical damage.
- Compress the strut or shock to test for resistance.
- Replace if any issues are found.

3. Inspect and Repair the Exhaust System

Visual Inspection:
- Examine the entire exhaust system for rust, cracks, or loose connections.
- Pay attention to exhaust hangers; replace if broken.
Tighten Loose Components:
- Use a socket set to tighten any loose bolts or clamps.
Replace Damaged Parts:
- If any exhaust components are damaged, replace them with OEM parts.

4. Drivetrain Inspection

Check CV Joints and Axles:
- Inspect CV joints for torn boots or play in the joint.
- Replace any damaged CV joints or axles if necessary.
Torque Specifications:
- Ensure all fasteners are tightened to manufacturer specifications.
