What Causes Noise at 60 MPH?
2 Answers
The causes of noise at 60 MPH include bearings and engine accessories. Below is a detailed explanation of the reasons for noise at 60 MPH: Water in Bearings: The first thing to consider is noise from one of the four-wheel bearings, meaning there is water or sludge in the tire bearings, causing pitting on the steel rollers. This situation can produce noise while driving, but the noise will be loud, resembling a humming sound. This noise does not occur at low speeds but appears at medium to high speeds, also manifesting as a humming sound. At higher speeds, resonance may also occur. This requires disassembly and inspection to confirm. Engine Accessories: Another cause is abnormal noise from engine accessories. At idle, there may be no noise or very little noise, but when accelerating, the noise increases and becomes abnormal. Sometimes there may be a screeching sound, other times a humming sound, or even a ticking noise. These are caused by wear and tear on the accessories. The noise is directly related to vehicle speed and engine RPM, so a thorough inspection and careful troubleshooting are necessary.
I was also quite puzzled when I first encountered this issue. As soon as the speed hits 60 mph, there's this buzzing noise, almost like an airplane taking off. Try to recall carefully whether the sound is coming from the chassis or the engine compartment. My guess is it's most likely a tire wear problem. If you have time, you can check the tire tread yourself to see if there's uneven wear or peeling. Worn-out bearings can also produce similar noises, especially when the sound gets louder during turns. Also, don't overlook wheel hub deformation—hitting potholes can cause high-speed vibrations. Lastly, let's not forget the brake pads; if a small stone gets stuck, it can make a rattling noise while driving. If you're really unsure, the safest bet is to take it to a repair shop and have them lift the car for a thorough inspection—safety first, after all.
