Hi Sam.
Yah was surprised to find out how tight bolts were and
the slight challenge to get them out. Mostly due to
work position as you said.
Will use torque wrench. Used to have a 69 Beetle. Did
the "no torque" thing with CV's on that car. They came
loose. Predictably. Like the sands of time.....
To all:
thanks for all the information. Really useful stuff
like don'e use washers over, torque, reasons for
colour of *sides* of outer ring etc. Should be "easy
street" with rest of install.
Have found 2 CV bolt plates (that's all they have/all
I need!) at local VW dealership. And brace yourselves,
they're only:
$1.88 C. Ea. !
Lucky me.
Maybe they'll have washers too, though I"m sure I can
match some up at the local FLAP.
Neil.
