The car have on the dash 285k km,i have changed the rear subframe bushing all 7pcs,rear ball joints,rear arms,all brake pads and rotors,brake calipers,complete suspension front and rear,front arms,all wheel bearings,gearbox mount,steering rods,front arm bushings etc..in the back i hear sometimes between 30-80km/h like a buzz noise with little vibration in the back,it's happen only when i'm driving in the city with constant acceleration,If i'm driving with brutal acceleration i have no sounds..few days ago i disconnected the abs switch and the car was making this buzz only when i'm turning to left and push middle or hard acceleration,but the noise was more pronounced in this case,but If i turning right and push the acceleration was no noise making..
