If your Mini Cooper Countryman (2011-2016) or Paceman (2013-2016) is making humming, grinding, or rumbling noises from the wheels, it might be time for new bearings. This TRQ 4-piece set includes both front and rear wheel bearing and hub assemblies – everything you need for a complete refresh. It fits base and S models, and matches OEM numbers like 31209813211, along with brands like MOOG (512543, 512573), SKF (BR930864, BR930865), and Timken (HA590423, HA590563). TRQ parts come with a 2-year/24,000-mile warranty (covers the part, not labor or other costs). Swapping worn bearings can seriously improve ride smoothness, reduce vibration, and prevent further damage. Make sure to confirm fitment for your specific year and model. A solid, complete kit to get your Mini rolling quietly and safely again.
