Newbie to this site, has anyone every replaced front wheel bearings on their 500 sec, mine is a 1985....thanks....Joe

 

I'm not sure how different it would be from the ones installed in my 91 560SEL but they are not that difficult to do. My question to you would have to be what is it that you are experiencing that has lead you to believe that yours need to be replaced? You can usually hear a failing wheel bearing before you can "feel" it. So you might want to respond with a few more symptoms that your front end is experiencing before you waste any time and money on repairs.
