206 buzzing sound from behind!

friends, I took the long road last night, came to Istanbul 700 km. When I wasted the vehicle downhill for the last 100 km, it came back and it was slowing down and slowing down.

I say have the wheel balls checked.

[QUOTE = expert_emre16] I would like to have a check of the ball bearings. If we have any other information, I would be glad if it goes, let's not change the parts from idle to the ground.
