Questions: why the car vibrates between 90 and 110 km / h?

"He car vibrates especially when circle between 90 and 110 km / h, vibrations disappearing below and above these speeds. I changed the car four tires, balancing them, and everything remains the same. What can be? Why you can continue vibrating the car?"

Response from our technical expert Luis Miguel Vitoria

We begin by discarding any possible cause. For example, bearings we assume that they have verified when changing tires and should be fine. We were not the case that the engine mounts have responsibility for their problem, because rather than velocity, They would have to generate these vibrations by revving. Anyway, you check them out.

Another possible origin or cause of the vibration your car to speed you point out would be a shock absorber supported in poor or whose operation outside defective. If this were so, it would be easy to check in driving, because it would become imprecise when circulated on bad ground. It is also possible that a bearing or wheel has been deformed by a knock or deterioration.
