Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, pry bar, wrench set
Sub-steps:
1. Remove the wheel on the side with the suspected faulty shock absorber.
2. Use a socket to remove the bolts securing the shock absorber to the upper and lower mounts.
3. Carefully pull the shock absorber out of its mounting position.
4. Compare the old shock absorber with the new one to ensure correct size and fit.
5. Install the new shock absorber, securing it with the bolts; tighten to manufacturer’s specified torque.

3. Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, ball joint separator, jack stands
Sub-steps:
1. Identify and remove any worn control arms, sway bar links, or ball joints as determined in the diagnostic phase.
2. For control arm replacement, unbolt the arm from both the frame and the spindle, using a ball joint separator if necessary.
3. Install the new control arm (or other components) and secure with the bolts; ensure to torque to specifications.
4. Reattach any sway bar links or bushings, ensuring they are properly greased if applicable.
