Installation Tips & Best Practices

1. Safely lift and support the vehicle to access the sway bar mounting points.

2. Remove the mounting brackets and old bushings.

3. Clean the sway bar surface and the mounting bracket area to remove gunk, corrosion, or old lubricant.

4. Press in the new W0406‑22 bushings carefully and ensure proper alignment.

5. Reinstall the mounting brackets and torque hardware to spec, avoiding overtightening.

6. After a short drive, recheck torque and inspect for any movement or noise.

Pro Tip: Use a compatible lubricant in the bushing bore to ease installation and reduce binding. Also inspect after 50–100 miles to ensure everything remains secure.
