Commentary not aimed at anyone;
One other thing, Don't strip threads. There is no excuse.
We all get that, but we have no control over what someone else has done previously (remember these trucks are senior citizens
and have likely been worked on by some hack a number of times). I've run across a number of threaded holes that are on a razor edge of being stripped already, and strip on the first turn of the wrench. At that point you need to break out the helicoil kit.
Excellent comments concerning chasing threads. If you reinstall a rusty, cruddy bolt in a rusty, cruddy hole, it's going to take some of the threads out. If you can't run them all the way in with your fingers, you either haven't cleaned them or you've cross-threaded them. Cross threading is a problem if someone else has already done that. Bolts have to be started STRAIGHT.
