Repair Instructions

  1. Replacing Worn Bushings:

    • Remove the affected suspension component (e.g., control arm).
    • Press out the old bushing using a hydraulic press or bushing removal tool.
    • Insert the new bushing and reassemble the component.

  2. Replacing Struts/Shocks:

    • Support the suspension with a jack.
    • Remove the strut/shock assembly bolts from the top mount and the bottom.
    • Replace with a new strut/shock assembly, ensuring all bolts are torqued to the manufacturer’s specifications.

  3. Replacing Sway Bar Links:

    • Remove the nuts securing the sway bar links.
    • Install new sway bar links and torque the nuts to specification.

  4. Lubricate Squeaky Components:

    • Apply penetrating oil to any squeaky joints or moving parts.
    • Avoid getting oil on rubber components as it can degrade the material.
