I ordered these top mounts (520-1655 and 520-1656) for the left and right side of my 2011 Nissan Sentra SL and they worked great. I didn't change the racks myself like a friend did for me, but he mentioned there were no problems. For reference, I ordered these Raybestos strut mounts along with KYB Excel-G struts and Raybestos 556-1108 bellows and everything went smoothly. My initial problem was a rattle in very low speed corners e.g. B. in a parking lot or when driving over bumps at low speed. These spare parts fixed my problems perfectly and at a good price. These parts prices are almost identical to Rock Auto, I usually go to auto parts destination.
