What should a driver check first if the vehicle steering wheel shakes or vibrates at highway speeds?
Answer and explanation
Correct answer: C. Front wheel balancing and tire pressure integrity
- Step 1: High-speed steering vibration diagnosis. Step 2. Vibration at 80-120 km/h is typically caused by unbalanced front wheels or uneven tire wear. Answer: Front wheel balancing and tire pressure integrity. Why not the others: Gearbox fluid causes gear whine, not steering shake; exhaust brackets cause rattling underneath; washer fluid is irrelevant.
