Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Ensure the vehicle is supported securely with jack stands before working underneath.

2. Inspect and Replace Suspension Components

Remove Wheel
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle with a jack and support it with jack stands.
- Remove the lug nuts and take off the wheel.
Check Shock Absorbers
- Inspect the shock absorber for any signs of leakage.
- If leaking, remove the old shock absorber by disconnecting the top and bottom mounting bolts with a socket set.
- Install the new shock absorber, tightening the bolts to the manufacturer's specified torque (typically around 40-50 Nm).
Examine Sway Bar Links
- Inspect the sway bar links for wear. If damaged, remove the bolts using a socket set and replace with new links.
- Ensure proper torque is applied (generally around 25 Nm).
Replace Bushings
- If any bushings are worn, remove the old ones by pressing them out or cutting them if necessary.
- Install new bushings using a bushing tool, ensuring they are seated properly.

3. Reassemble and Test

Reattach the wheel and lower the vehicle to the ground.
Tighten the lug nuts in a crisscross pattern to the specified torque (typically around 120 Nm).
Test drive the vehicle over bumps to confirm the popping noise has been resolved.
