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 ensure safety during repairs.

2. Inspect and Replace CV Joints

Tools Required: Socket set, pry bar, torque wrench, CV joint boot clamp tool
Remove the wheel to access the CV joint.
Inspect the CV joint boot for tears or leaks. If damaged, replace the CV joint.
Remove the axle nut using a socket and ratchet.
Use a pry bar to detach the CV joint from the wheel hub.
Install the new CV joint by reversing the removal steps and ensure to torque the axle nut to the manufacturer’s specifications (typically around 200 Nm).

3. Check and Replace Steering Components

Tools Required: Wrench set, torque wrench, steering rack removal tool
Inspect the tie rods and control arms for wear. Replace any worn components.
To replace tie rods, loosen the lock nut and remove the tie rod end from the steering knuckle.
Install the new tie rod end and tighten the lock nut to the specified torque (usually around 35 Nm).
Recheck the alignment after replacement.

4. Inspect and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench
Remove the wheel and brake caliper to access the wheel bearing.
Inspect the wheel bearing for noise or play. If defective, remove it using a bearing puller.
Install the new wheel bearing and torque to the manufacturer’s specifications (typically around 80 Nm).
