Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery for safety.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar, jack, jack stands.
Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access suspension components.
3. Visually inspect control arms, bushings, and struts for any signs of wear or damage.
4. Replace any worn components with OEM or high-quality aftermarket parts.
5. Torque all bolts to the manufacturer’s specifications.

3. Inspect and Replace CV Joints/Axles

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Remove the front wheels again if not already removed.
2. Check for any tears in the CV boot; if damaged, replace the boot and inspect the joint.
3. If the CV joint is worn, remove the axle by loosening the axle nut and disconnecting it from the hub.
4. Install a new axle and torque the axle nut to the specified value.

4. Inspect Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
Sub-steps:
1. Test for play in the wheel bearings by checking for lateral movement.
2. If play is detected, remove the wheel hub and replace the bearings.
3. Reassemble and torque the hub assembly to manufacturer specifications.
