Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise the rear end using a jack and jack stands.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Remove the rear wheels for better access to the suspension components.
2. Locate the shock absorbers and inspect for leaks or physical damage.
3. If damaged, unbolt the upper and lower mounting points of the shock absorber using a socket set.
4. Remove the old shock absorber and replace it with a new one, ensuring it is the correct part for the Tiguan.
5. Torque the mounting nuts to the manufacturer's specifications (usually around 30-40 ft-lbs).

3. Replace Worn Bushings

Tools Required: Socket set, bushing removal tool, lubricant
Sub-steps:
1. Identify any worn bushings in the suspension arms or sway bar.
2. Use the bushing removal tool to take out the old bushings.
3. Lubricate the new bushings and install them into the suspension components.
4. Ensure that they are seated properly and reassemble the components.

4. Inspect and Replace Sway Bar Links

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the sway bar links and inspect them for wear or damage.
2. Remove the bolts securing the sway bar links to the sway bar and the lower control arm.
3. Install new sway bar links and torque bolts to manufacturer's specifications (usually around 25-30 ft-lbs).

5. Reassemble and Test

Reinstall the rear wheels and lower the vehicle.
Tighten all bolts and check the torque specifications for all components.
Test drive the vehicle to ensure that the noise has been resolved.
