Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues while working.

2. Lift the Vehicle

Use a jack to raise the front of the vehicle and support it with jack stands.
Remove the front wheels for better access to the suspension components.

3. Inspect and Replace Components

A. Sway Bar Links

Inspection: Check for play in the sway bar links.
Replacement:
- Remove the bolts securing the sway bar links using a socket set.
- Replace with new sway bar links, ensuring they are torqued to manufacturer specifications (typically around 40-50 ft-lbs).

B. Struts and Shock Absorbers

Inspection: Look for any oil leaks or physical damage.
Replacement:
- Detach the top strut bolts and lower mounting bolts using a socket set.
- Remove the strut assembly and replace with a new unit, torquing bolts to manufacturer specifications (usually around 35-50 ft-lbs for lower bolts, 15-20 ft-lbs for upper bolts).

C. CV Joints

Inspection: Check the CV boots for tears and the joints for play.
Replacement:
- If damaged, remove the axle nut and detach the axle from the hub.
- Replace with a new axle, ensuring proper lubrication and torque (generally around 180-220 ft-lbs for the axle nut).

4. Reassemble and Lower Vehicle

Reinstall the front wheels and lower the vehicle.
Reconnect the battery.
