Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace CV Joints

Inspect: Remove the front wheels to access the CV joints.
Check for Damage: Look for torn boots or grease leakage.
Remove: Unbolt the CV joint from the wheel hub and the transmission side.
Replace: Install the new CV joint in reverse order of removal. Ensure proper torque specifications (typically around 30-40 ft-lbs for axle nuts, but consult service manual for exact value).

3. Inspect and Replace Wheel Bearings

Remove: Take off the brake caliper and rotor to access the wheel bearing.
Inspect: Check for any roughness or play in the bearing.
Replace: If faulty, remove the bearing and install a new one following the manufacturer's specifications. Use a bearing press if necessary.

4. Check and Replace Suspension Components

Inspect: Look at control arms, bushings, and struts for wear.
Replace: If any component shows wear, remove and replace it with new parts.
Reassemble: Ensure all bolts are torqued to manufacturer specifications.
