BTW I whacked the spindle with a nylon dead blow hammer. My guess was
that was enough brutality or do Mercedes like it rough....

I know the recommended procedure people are following for setting
front wheel bearing is to use a dial indicator and, with the base on
the rotor measure the end play of the spindle. People are
recommending half a notch if one's dial indicator is measuring
thousands.
My question is that I have a 1977-1988 Mercedes Service Manual for
Chassis and Body Series 123. In section 33.3-300/2 it states :
"6 Place tester on front wheel hub and set dial gauge to approx. 2
mm pre-load."
"7 Check end play of wheel hub by pulling and pushing on flange."
Two millimeters is 0.078".... that's a lot of rattle room.
If you go to this link, at the bottom there is a pdf file which is a
copy of the manual I am referring to. Step 6 pg 266,
What gives???
Can't be right. 0.00078" would be within the recommended range of 4
to 8 ten thousands. (0004" to 0008").
If I'm in a hurry I tighten the nut while turning the wheel until the
bearing is locked. Then I back it off one third turn and whack the
spindle with a hammer to release the bearing.
If not in a hurry I use a cheap micrometer that is graduated in
thousandths of an inch and keep the needle between two adjacent
thousandths marks while pulling the wheel. Never had a bearing run hot.
