Failed Wheel Bearing
Wheel bearings usually appear on the top of metal pipes, and it helps to reduce friction significantly during movement.
Therefore, this part is often straightforward to rust after use. Currently, the car sounds like a helicopter or a lawnmower. This sign indicates that the wheel bearing part has failed and needs repair.
Due to the lateral movement, the wheel bearing is very susceptible to failure and produces annoying noise.
It will make a move a lot more complicated. Moreover, it is hazardous for you to continue driving with damaged wheel bearings. Stop the vehicle as soon as you notice the problem.
How to fix
Even if you hear the mower while driving, you must check each wheel for all faulty bearings. To do this, raise each tire slowly and turn the wheel; the creaking sound will help you identify the problem.
Blown Head Gasket
The head gasket is one of the essential parts of the engine system because it prevents engine oil and coolant from leaking into the environment.
When a damaged head pad makes a lawn mower sound, it harms your hearing. Moreover, this will release many dangerous gases into the vehicle’s interior. It not only affects passengers but also reduces the speed of the car significantly. At this moment, brake pedal squeaking may also appear.
