- Check for leaks or physical damage.
- If defective, remove the bolts securing them and replace with new units, ensuring they are torqued to manufacturer specifications.
Inspect Control Arms and Bushings:
- Examine control arms for cracks or bends.
- Use a pry bar to test bushings for excessive wear; replace if necessary.
- Remove bolts and replace control arms as needed, ensuring proper torque.
Check Sway Bar Links:
