Mercedes tools (W202 rear wheel bearing replacement)

[MarkC]

I ordered and received a rear bearing repair kit form FastLane here. The replacement bolts for the CV joint take a 12 point male torx driver. This is contrary to the pic showing a female 6point torx socket needed for the same bearing kit:


Where can I buy a 12point male torx driver (I have a normal 6 point T50 torx driver that fits, but I suspect I'll need a 12 point for strong enough contact)?

Also, found a tool designed to remove/replace the rear wheel bearing here:

But at $341 seems a bit steep, anyone replace a rear wheel bearing using another tool, technique or (?) ?

I've never done this before, nor do I have any literature or repair guide. Anyone know the torque requirement for the bolts?

TIA
