Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels, depending on where the popping sound is originating.

3. Inspect and Replace Suspension Components

Sub-step 1: Visually inspect the shock absorbers and strut mounts for leakage or damage.
Sub-step 2: If damaged, remove the strut assembly by unbolting it from the suspension and steering knuckle.
Sub-step 3: Replace the strut or shock absorber with a new part, ensuring it is properly aligned and torqued to manufacturer specifications.
Sub-step 4: Reinstall the wheel and lower the vehicle back to the ground.

4. Inspect and Replace CV Joints or Axles

Sub-step 1: If the CV joints are suspected, remove the axle nut and disconnect the lower control arm.
Sub-step 2: Slide out the CV axle and inspect for torn boots or worn joints.
Sub-step 3: Replace the CV axle if any issues are found, ensuring proper installation and torque specifications are followed.

5. Check Exhaust System

Sub-step 1: Inspect the exhaust hangers and supports for any looseness or damage.
Sub-step 2: Tighten any loose bolts or replace damaged hangers to eliminate noise.
