I have done quite a few things now on my car and don't own a torque wrench. I pay attention to how hard the nut/bolt is to remove and use same approximate effort to redo (for example the nuts on the transmission pan are not stressed down very hard).....but I know that is far from precise.

Note that I am not working inside the engine.

Any comments on how important it is to torque exactly right? Even the wheel nuts have a torque requirement "by the book".

I have seen some posts where apparently experienced types talk of a one "ug" vs. two "ugs" torque concept and I have watched qualified mechanics work on my suspension without ever touching a torque wrench. So, just how important is it?
