JMela, I got help from someone and it took us a full morning to take the axle out. But we are not professionals. You will need two jack stands and a jack that you can put under the trail arms when you remove them with the suspension springs. The normal W108 MB jack won't do, unless you instead put something under the trail arms to retain them when they are unbolted and lift the car with the MB jack. Start by undoing all what is connected to the axle: brake lines, emergency brake cables, drive shaft, shock absorbers. Then undo the front of the trail arms making sure they are retained by something, otherwise the suspension spring will push them down violently, and the car will also fall down if it is not held by a jack or a stand. In our case, things went smoothly, no spring jumping all over the place. But it can be dangerous if miscalculated. Then I undid the central bolt in the trunk. I had to hammer the central arm down (with the bolt back into it half way) as the arm had seized in the mount. And the axle was out. While manovering the axle, make sure the right part does not come down all the way violently as this can damage the central casing under the rubber. You won't see it without taking the rubber out but it can brake under there.
