I have had good luck on the MB (and many other cars) using a small 2-arm puller for steering balljoints. No damage this way.
There are many specialized tools marketed for this purpose.
Pickle-forks should be a last resort solution, because the rubber boots are very likely to get damaged.
Of course, if Larry's big hammer method works, I may stop using pullers altogether. I really like using a big hammer whenever the chance arises. What is the MB part number for the special 4.5Kg (12 Lb) balljoint removal service tool?
Back to pullers for a minute.
If I were buying a new puller, I would consider buying a Posi-Lock puller over the standard design. I just hate when my puller slips off...
