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 E30 M3, especially when turning, it's likely the bearings.
The easiest way to verify if it's your wheel bearings is to jack the front of the car, put a hand on top and on the bottom of the wheel in question, and try to see if the wheel has any play. If it does, it's best to change the wheel bearings before they become more than just an annoying sound and leave you stranded on the road.

E28 hub on E30 M3: for decades the E28 was a suitable alternative to the very expensive Genuine BMW hub. It required the ABS tone ring to be swapped but it was otherwise a direct replacement. However, starting c. 2024 the casting of the E28 hub was changed and the M3 ABS ring was no longer a direct fit (too large). Then in 2026, the OEM replacement E28 hub was discontinued altogether. This leaves the Genuine M3 hub as the only premium bolt-on replacement hub and bearing available.
