Hello, for some time now my Volvo has been running at higher speeds – from about 50/60 kmh – loud running noises. My tyres can’t be because I’ve been driving for a while and the noises have not been present before. It comes from the front, probably left side. To check, we went as follows: vehicle is bucked up, right front wheel is manually blocked, engine is switched on, individual gears are switched on and there was a grinding noise in the area between wheel sprocket and gearbox at higher speeds. Then left front wheel is blocked, engine is blocked, and fixed that with increasing wheel speed on the right, a flickering noise in the area of the gearbox rose parallel to it. Then, to check both front wheels run at the same speed, only the grinding sound of the left side was noticeable. Both brakes were completely open and thus had no contact to the brake disc. We checked gear oil before, the oil stand was flawless! I am worried that it could be the gear? Or can it be the wheel bearing? Evt. other bearings in this area can help me.
