re-positioned it and tightened down the nut firmly. He also
tightened the other one to forestall the problem......
It's not a "rip-off" to install new wiper arms. The fellow that
fixed your wipers also did a legit repair too. It's the hub that
actually has the splines cast into it. The wiper arm does not
have splines, but you create them when you install the arm
and tighten the nut down. The wiper arm is made out of
a softer pot metal, and it simply forms itself to the splines
on the hub. You may be fine for a while, you may be
fine forever...who knows. But for a dealership (who has
to stand behind every repair), it's much simpler to install
a new wiper arm, and torque it down properly. Pretty
much guaranteed then that it will not fail any time soon.
If this fix that you just got fails, is that tech going to
refund you your money and the tip? Doubt it, and
he shouldn't, as the repair is one of those "hey, lets
give this a shot and if it works, you are on your way
for very little money" type of repairs.
