This is a new very high quality and very correct set of steering knuckle bearings. These are for the steering knuckle king pins. They are what the complete knuckle assy pivot on. These are almost always totally worn out or rusted beyond use when found. This is a very important part of your steering and front axle system.  These are well known brands of bearings and races so you know they are very high quality. (Timken, National) We never know which of the two brands we will get in so there is no choice on the brands. We will not carry off brand China or India made bearings which are inferior quality.   This will fit the MB, GPW, CJ2A, Cj3A, Cj3B, M38, and M38A1.  QTM Parts
