changing wheelbearing

I assume the wheel bearings on a 124 body are similiar to a 123 chassis car.

You need to loosen the allen bolt that retains the adjuster nut. Remove the nut and hub. Remove the inner grease seal along with the inner and outer bearing. Then using a punch you tap out the inner and outer bearing races. You also tap in the new inner race, outer race and the grease seal. I just had the machine shop at a local auto parts store do it for one of my 300D's. They charged me $15 labor. The bearing kit including the grease seal was $29.

It's a 4MATIC model. Is the wheel bearing any different than the "ordinary"
