- Inspect for leaks or physical damage.
- If damaged, replace with new shocks/struts, following manufacturer specifications for torque values.
Inspect Control Arms and Bushings:
- Remove the control arm bolts and lower it for inspection.
- Replace any worn bushings and ensure that control arms are not bent or damaged. Torque bolts to manufacturer specifications during reinstallation.
Examine Sway Bar Links:
- Remove the sway bar link bolts using a wrench.
- Check for play or damage in the links and replace if necessary.

4. Reassemble and Lower Vehicle

Reassemble all components in reverse order of disassembly.
Double-check all bolts are torqued to the correct specifications.
Lower the vehicle carefully and remove jack stands.
