My W123 300CD, I got aftermarket wheels, and one lug bolt was included too short and it stripped out my hub. I had the mechanic replace it. Her is what he did. Took the wheel off, took the disc, and caliper off, take off the emergency brake parts, take the nut off, then take the drive axle out, then pushed the hub out with a mercedes tool, took off the bearing witha mercedes tool, then reinstalled a new bearing and replaced the new hub. It seems like a really hard job without the mercedes tool.
No Benzes in the stable at the moment, but itching for one again.
