Turns out that I have 1/16" vertical movement in the left rear hub of the SEC. Not good. I've torn the front end apart many times but never went into the rear hubs. Do I need to remove the axle? The manual (35-130) indicates the use of a "slot wrench" - what is that and is it really needed to get these apart/together??

The parking brake shoes are good and the disc brake rotor and pads look fine. Do I likely need only a set of rear bearings and grease seals??

Thanks,
Mike

Here's a link to my DIY. You probably do need the special tool. Perhaps to help me recoup some costs you would like to rent mine? It was $120 at the dealer. I could ship it to you for $20 you pay shipping back. Or, maybe you could find it cheaper on the net. I did read though that some people bought the non OE tool and it broke on them. Anyway, let me know.

Haha, it looks like our posts crossed, Greeney!

This may be of only little help, but I'm not pretty sure you have to wonder that much for one sixteenth of an inch, which is not much. By the way, have you unbolted your wheels recently? If you did and have not retightened them since, maybe one or more bolts loosened? For slot wrench, see the attached picture. I'm sure you have those already. The axel end, if your not able to push it (never changed rear hub in mercedes, but on other cars), then you might use a puller, in order to free the hub. Also, I think the axle end is covered with constant velocity joints, which may explain the slot wrench. If ever I'm wrong, just ignore irrelevent infos...

The special tool seems to come with the new hub, doesn't it?
