Solution

1. Preparation

Gather tools and parts needed for repairs.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electrical components.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect strut mounts, control arms, and bushings for wear or damage.
3. If any components are damaged or worn, remove them using a socket set and replace with new parts.
4. Torque the new components to the manufacturer's specifications.

3. Examine and Repair Exhaust System

Tools Required: Wrench set, exhaust hanger removal tool
Sub-steps:
1. Inspect the exhaust system for loose clamps or damaged sections.
2. Tighten any loose bolts or replace damaged hangers that may be causing the popping noise.
3. If necessary, replace any corroded or damaged exhaust parts.

4. Check CV Joints and Axles
