Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery if necessary for electrical components.

2. Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack and jack stands, pry bar, impact wrench (if available).
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the side where the popping is present.
3. Inspect and remove the sway bar links if they are worn. Use a socket set to remove the bolts.
4. If shocks or struts are determined to be faulty, remove them by unbolting the top and bottom mounts.
5. Install new shocks or struts, ensuring all bolts are torqued to manufacturer specifications.
6. Reinstall the sway bar links, ensuring they are properly secured.

3. Tighten Loose Hardware

Sub-steps:
1. Check all suspension-related bolts and nuts for proper tightness.
2. Use a torque wrench to tighten bolts to the specified torque settings found in the service manual.
3. Inspect bushings and replace if damaged or excessively worn.
