Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electrical components).
Wear safety goggles and gloves.

2. Replace Worn Suspension Components

Struts/Shocks Replacement
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the strut assembly.
3. Disconnect the strut from the lower control arm by removing the bolts (use a socket set).
4. Remove the top mount bolts from the strut tower in the engine bay.
5. Remove the strut assembly from the vehicle.
6. Install the new strut by reversing the removal steps, ensuring proper alignment.
7. Torque all bolts to the manufacturer's specifications (typically around 50-70 ft-lbs for the strut bolts).
Control Arm/Bushing Replacement
1. If the control arm is damaged, support the lower control arm with a jack.
2. Remove the bolts securing the control arm to the frame and the steering knuckle.
3. Replace any worn bushings using a press or a bushing tool.
4. Install the new control arm and torque bolts to specifications.

3. Replace Sway Bar Links

Locate the sway bar links, usually found connecting the sway bar to the control arm.
Remove the nuts securing the sway bar link to the sway bar and control arm using a socket set.
Install the new sway bar links and torque to specifications.
