Yes i have good tyres 255 50 r19 front 285 45 r19 rear,ball joints already changed front and rear,the wheel bearing are new all 4,the cv axles joints don't play...the noise it's coming from the right rear and sometimes from front left,but on the front it's not so loud,and when i have this sound it's cut a little bit from acceleration,but it's not continous noise,it's not permanent,my mechanic think the problem it's coming from rear differential,but If start drive with hard acceleration i don't hear any noise,it's making only when i driving normal with constant speed in the city...it's a noise like the tyres are crawls on the asphalt...the mechanic checked the wheel speed sensor and he didn't see big diferences between the wheels. I checked with inpa/ista+ and no errors,only sometimes i find error "electronic brake distribution" but how i know this is a specific error and don't have specific symptoms...
