The supplier lists them for xDrive versions of the 5 Series, 6 Series and 7 Series, including the 528i, 535i, 550i, 640i, 650i and 750i, and gives BMW reference numbers 31124081431 and 31124081432 among others. Easy Life Markets sells the two arms together, because on these cars the left and right arms wear at much the same rate.\u003c\/p\u003e\n\n\u003cp\u003eBMW uses two lower arms on each side of the front axle of these models, rather than a single wishbone. The forward one runs from the subframe to the bottom of the wheel carrier at an angle and takes most of the braking and acceleration loads. In BMW catalogues it is often called a tension strut or thrust arm. It has a ball joint at the wheel end and a large bushing at the body end, and both wear out. When they do, the steering wheel shakes under braking and the front of the car feels less precise.
