Can and would someone explain to me the proper procedure to remove and replace the rear wheel bearings in a 1982 300D turbo. While I had the differential open to replace the seals and drive axels I removed the calipers and rotors and rotated the wheel hub. Low and behold that is where my rear end whirr is coming from. I looked closely and saw the two locking spots on the inside of the hub. It looks like I need a castle wrench to remove the lock nut for the assembly. I called the local dealer to find out if I can order the wrenches from them. A full day on the phone back and forth with them resulted in nothing. They gave me an 800 number to call. I called and spoke with a tech there and he said I needed some tools but would not tell me which ones. I also asked if there was a special procedure to remove these bearings and he said yes, but would not enlighten me. He was very clear, that if I wanted to know how I would have to purchase their CD. I am not interested in doing that at this time. Can anyone here help me out? Thank you in advance for your help.

You should probably go ahead and order the CD. Most likely if you are going to attempt to do this repair you will be doing other repairs also.. Unless you are going to get rid of it.. Then you could sell the cd with the car... Second if you get the tool but not the special instructions you could mess it up and then have to start all over again..
Get the CD

The rear bearings on a 123 chassis can be a bear to do. Even getting the hub out can be difficult. The two tapered bearings have a crush-sleeve between them that gets squeezed onto the hub shaft and it has to be tightened more than you'd think to give the required clearance going back together. We used to have an old rear rotor with a tube welded to it to hold a jack handle so we could tighten the nut on those. Of course, short "bursts" with a good 1/2" drive air gun will do the same thing. It's just a matter of choice.
If you really want to do it yourself,the tool(s) can be had from either Baum Tools in Florida or AST(Assenmacher Specialty Tools) in Colorado. You can find both on the web. When I was still at the dealer AST was supplying some of the tools for MB. Regards, Randy D. |

You might want to think about exchangeing the whole rear control arm with a used one. I did so on my 84 300D at a delivered by UPS from a local junk yard for $153. The car has been on the road for 2 months now with no problems. Changing the control arm was not a difficult job. I took a chance on a used arm but so far it has worked out for me and I got the car on the road fast.
