Hey guys why is the brushroll on my windtunnel make so much vibration noise? It's loud when I'm vacuuming not smooth.. And horrible when its on the uoright position.. Very loud.. It's the BRUSHROLL because I ran it without and it's nice n quiet.. Put it back in and it's vibrating bad like maybe the bristles are hitting the duct of the brushroll housing? Not sure.. Anyone have any suggestions?? It's the original hoover BRUSHROLL that came with the vac model U5454-900
