This part is listed by BMW as BMW part number 31221139348 (31 22 1 139 348) and is described as OEM Front Wheel Bearing & Hub for BMW E34, E32, E31 and has the standard 83mm diameter bearing.
The Front Hub (Wheel Bearing) isn't something most people think about until it's time to replace them. They generally work seamlessly... Until they don't. If you've noticed a groaning from one or both of the front wheels on your E34 5-Series, E32 7-Series or E31 8-Series, especially when turning, it's likely the bearings.
Please note: NOT for 540i 6 speed "M Sport" models (which used a different larger wheel bearing, like that of the E34 M5, part # 31212226640).
This is an OEM Hub Assembly manufactured by FAG-Schaeffler - the original supplier to BMW for this part, as well as many other engine components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
