The solution to the car still making a humming noise after replacing the bearing is: Remove the drive belt connected to the crankshaft, generator, compressor, power steering pump, etc., on the engine. If the noise disappears after starting the car, turn off the engine and manually rotate or shake those drive components to see which one is loose or making abnormal noises. The functions of the bearing are: 1. To ensure that the shock absorber can rotate with the wheel when the vehicle is turning, maintaining steering flexibility; 2. The outer ring of the pressure bearing is made of rubber, which maintains a soft connection between the body and the shock absorber, preventing vibrations from uneven road surfaces from being transmitted to the body through the shock absorber while driving.

Which SUV models come with a 1.8T engine?

Currently, only the Volkswagen Tiguan, Skoda Yeti, SAIC Roewe W5, and Hawtai Santa Fe are equipped with 1.8T engines. Both the Tiguan and Yeti are derived from the Volkswagen PQ35 platform, essentially urban SUVs designed based on the Sagitar chassis, performing decently on city paved roads. Additional Information: The 'T' in car displacement stands for turbocharging. A turbocharged engine compresses air before supplying it to the cylinders to increase air density and intake volume. With increased air intake, the fuel supply can be proportionally increased, thereby boosting engine power. The 'L' in car displacement stands for naturally aspirated. Naturally aspirated is a type of car intake system where air is drawn into the combustion chamber without any supercharger, relying solely on atmospheric pressure. Naturally aspirated engines offer smoother power output and more direct responsiveness compared to turbocharged engines.
