Do an search and you can find the "over the counter" part numbers for the wheel bearings I posted when I redid the ones on my 300D. Go by you local bearing supply company and they are available. The tricky part is getting the correct "tightness" on the bearings when you put the hub back on the car. You have to develop a "feel" for it versus just aligning the nearest hole for the cotter pin. Pretty straight forward once you do a couple.
