Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench, jack stands
Raise the vehicle using a jack and secure with jack stands.
Visually inspect the suspension components (control arms, bushings, struts, shocks) for any signs of wear or damage.
Use a torque wrench to check and tighten any loose bolts to the manufacturer's specifications.

3. Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, pry bar
If any components are found to be worn or damaged, remove them:
- For struts/shocks: Remove the mounting bolts and detach the strut from the assembly.
- For control arms: Remove the bolts securing the control arm to the frame and knuckle.
Install new components in reverse order of removal, ensuring all bolts are torqued to specification.

4. Inspect and Secure Exhaust System

Tools Required: Wrench set, exhaust hanger tool
Inspect the exhaust system for any loose hangers or damaged sections:
- If hangers are worn, replace them.
- Tighten any loose bolts or clamps securing the exhaust.

5. Reassemble and Lower the Vehicle
