Front wheel bearing torque?

Hello All,

I drive a 1993 300E 2.8 24V. I am looking to repace the front wheel nearings. Since, on a previous car, I already blew one axle by tightening the nearings to tight, I am looking to find out how I correctly tighten the nuts on the bearing. Are there any measurements in Torque that are to be followed or is there another way that I can do it correctly without all kinds of expensive or mercedes explicit tools?

Untill now I just leave a little play but that ofcourse is a pretty coarse method of adjustment.

Thanks and have fun,

marc
