Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Inspect and Replace Worn Suspension Components

Control Arms and Bushings
1. Remove the lower control arm bolts using a socket set.
2. Inspect bushings for cracks or deterioration; replace if necessary.
3. Install new bushings and torque the bolts to the manufacturer’s specifications (typically around 80 Nm).
Struts/Shocks
1. Remove the strut assembly by unbolting it from the knuckle and top mount.
2. Inspect for oil leaks; if leaking, replace with new struts.
3. Reinstall the strut assembly and torque the top mount bolts to approximately 25 Nm.
Sway Bar Links and Bushings
1. Unbolt the sway bar links using a wrench and socket.
2. Inspect for any play; replace if worn.
3. Install new sway bar links and torque them to the manufacturer’s specification.

3. Reassemble and Lower Vehicle

Reattach any components that were removed during the inspection process.
Lower the vehicle off the jack stands and remove wheel chocks.
Perform a final inspection to ensure everything is secured properly.
