Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect the shock absorber for leaks or damage. If defective, remove the bolts securing the shock to the upper and lower mounts.
4. Install the new shock absorber by reversing the removal process and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs for lower bolts).
Sway Bar Links:
1. Locate the sway bar links and inspect for wear or detachment.
2. Use a socket set to remove the bolts securing the sway bar link to the sway bar and the lower control arm.
3. Install new sway bar links and torque to appropriate specifications (usually 30-40 ft-lbs).

3. Inspect Exhaust System

Exhaust Hangers:
1. Visually inspect the exhaust system for any loose hangers or broken mounting brackets.
2. If any hangers are damaged, replace them with new ones to ensure the exhaust is securely held in place.
