A torque wrench is the way to go in most situations dealing with a threaded aluminum housing, most involving a bearing pre-load, and pretty much any time you are dealing with a long (over 2"
fastener, especially if you have an undercut shank (smaller shank between the head and threads than normal. The old Wrench arc method was 1.5 to 2 flats past contact on flat surfaces, and I think, 1.5 turns past with a lock washer, and lots of mechanics used it for many years. You will eventually, develop a feel for how much "stank" you are applying, but after over 20 years, I still just keep the torque wrench out when I'm working. If it's there, and there's no rush, might as well. Someone went to the trouble to figure out the ideal torque range. Gotta make them "train drivers" feel useful.
