.... values, that is.
Doing suspension work. There's one bolt that everyone says "dude, you gotta replace that": the strut pinch bolt. So that's a no brainer.
But there's a bunch of bolts that
A) VW says you should replace (but nobody does)
and
II) have a torque spec. that includes something like " + 180°"
For the ones without (II), above, I'm comfortable re-using a "must replace" bolt, tightening to the specified torque.
But what about the ones that include a "this much more"? Do you do exactly that, even on a re-used "must replace" bolt?
The ones I'm thinking (probably too hard) about:
top mount bolts, #13:
LCA mount bolts and ball joint lower nuts, parts #7, 8, and 4:
and parts #1 and 10:
I'm conflicted because usually "+xxx°" means "tighten to yield", which means "don't reuse" and more explicitly, "if you keep tightening to yield, they'll end up like this: (motorcycle brake caliper mounting bolt. I had the torque wrench set to "lb-ft" instead of Nm. I caught it before riding.)
+180° seems like "to yield", so .... what does everyone do here?
