@menjicar: BMW wheel bearing 🙊 #n54 #bmw #wheelbearing #fixingcars #335i

Karl Sigge Maxe :

Oem axles are hollow to save weight, it’s really good to swap for non hollow if you drive the car hard and or drift with the car. My friend blew both his after he welded his diff, but had no issues after swapping with non hollow.
