Another method I have used to break stubborn fasteners loose is using a
punch - either a dull, cutting point or a pointed punch placed against the
head of the bolt and whacked hard in the intended direction with a BFH.
Often, the force is enough to break it loose. I replace the fastener of
course. Although recently when I used this method to break loose some
stubborn intake manifold bolts on my 91 300D I reused a couple until I got
replacements - the originals would have lasted a long time but I wanted
nice clean allen bolts.

John - thanks for the info - it really helps. The bolts on the half
shafts
of this car are definitely 12-point, or triple square. The Torx 50 is a
slightly loose fit, and since the spec for the "50" size is 8.83mm point
to
point, I'm assuming that the XZN-10 is appropriate.
Now the main problem will be to somehow get the 2 stripped out (from
using
the Torx bit) screws out - a feeble attempt with a vise grip resulted in
"polishing" the outside of the bolt head! Probably doesn't help that M-B
probably used Lock-Tight on the threads, 16 years ago! May have to
resort
to using the "blue wrench" (torch)!
No Problem. MB does have a loctite fetish-- they dont like things
coming loose. Ever. I think thats why the never use anti-sieze compounds
either (Differential drain plugs @300ft-lb to break loose anyone?)...
Does an Easy-out of any size fit the opening? Have you considered
judiciously grinding off the head (dremel and cut-off wheel?) and then
going after the remaining bolt with vice-grips or a small pipe wrench when
the axle is off? It should turn a LOT easier with no stretch on the bolt.
(pipe wrenches are great when you have a stubborn part because they bite
harder as more force is applied ... and you will end up replacing the part
anyhow)
