When I greased the front wheel bearings on the '83 300D the new bearing would not go on. There was a ridge next to where the bearing inner race seated. I sanded the ridge as much as I dared with emery cloth but the new bearing would still not go and I didn't want to try and drive it on. I took the new bearing back and got another new bearing, thinking the first one might be off-dimension but it wouldn't go on either. In desperation I went across the street to Autozone, thinking they might have foreign bearing with less precise dimensions, and got a Chinese bearing which went on with no problem. That was about 8 years ago and the Chinese bearing has caused no problems.
I've often wondered how that ridge around the stub axle formed. I didn't think high strength steel such as is used in stub axles is malleable/plastic enough for a frozen bearing to create a ridge without it being raised to a temperature up in the 2000 degreeF range. That is pretty much true when working with a forge. High strength steel has to be a dull shade of red before it can be shaped. It would seem that such a temperature would make the stub axle unusable.
