Hello everyone, I have a 2004 model 307 xt premium vehicle. At normal speeds, the car goes very quietly, but as soon as I get to 110, the hum begins to come out. As for 115, there are only 110 cuts. What is the reason, do you have any guesses?

Thanks everyone already :)

The ball would wait until 110, two had happened before, 30 was the start, and it was never cut. I changed the balls, it improved. This is a different 110, then it passes right away

It can come from bumper parts. For example, if you wear lip, your vehicle will do more harm than acceleration.
As the friend says, the bearing can come from the balls. Consider the washing machine in the spin program, it does not make a lot of noise at low speed but it increases in the hum as the speed increases. Actually, there is always a buzz, but you don't hear. It can reach a noticeable degree in that km. control is useful.

The gas is increasing in pressure, decreasing from gas and it is coming from the gearbox if it is not idle. Generally it is said that it does some speed range in the peugeot group.

I do it whether I press the gas or not, and I wasted it today and tried again 110-115. I guess not from the gearbox. Let me show you at the weekend
