- Replace any damaged tires.
Balance Tires:
- Use a tire balancing machine to balance all four tires.
- Adjust weights as necessary.

2. Wheel Alignment

Alignment Procedure:
- Use a wheel alignment machine to check the alignment settings.
- Adjust the toe, camber, and caster angles according to manufacturer specifications.

3. Inspect and Replace CV Joints/Axles

Visual Inspection:
- Look for torn CV boots or leaking grease.
Replacement:
- If damaged, remove the affected CV joint or axle assembly.
- Install a new CV joint or axle, ensuring proper torque settings are followed for all bolts.

4. Engine and Transmission Mounts

Check Mounts:
- Visually inspect all engine and transmission mounts for cracks or excessive movement.
Replace Mounts:
- If mounts are found to be defective, remove the old mounts using a socket set.
- Install new mounts, ensuring they are torqued to the manufacturer's specifications.

5. Final Inspection and Adjustment

Recheck:
- After all repairs, recheck the wheel alignment and tire balance.
- Ensure all components are secure and functioning properly.
