Replace: Install the new shock absorber, tightening bolts to the manufacturer’s specified torque settings (refer to the vehicle manual).
Reinstall: Reattach the wheel and lower the vehicle.

4. Check and Replace Sway Bar Links and Bushings

Remove: Unbolt the sway bar link from the sway bar and control arm.
Inspect: Check the bushings for wear and replace if necessary.
Install: Attach new sway bar links and tighten to specified torque.
