I think this picture is taken out of context somewhat. There is more than 1 style of bushing for W124/W201 chassis. For example, the (early) 260E's and W201's had a bushing that looks like 17a that may very well be a steel sleeve.

However, '87 300D's have bushings that look like 17b, with a centering sleeve 18.

You can't push it out from one end to the other.

Regards,
