Thanks to many of you fine folk since 2016, I've been doing more and more DIY stuff, of which my most appreciated is seasonal tire changeovers.
I bought a 3 ton floor jack, made a rail saver from a hockey puck, got all the impact sockets I'd ever need, and of course a breaker bar and separate torque wrench (along with anti seize, etc).
I find that the "manual method" requires 2-3 re-torques for my cars, but my dad's 2006 RX seems to require mid-season re-torques (they loosen considerably after a few weeks). I SUSPECT this is because the rims are 15 years old and my dad always went to a Green and Ross location that perhaps has less than a stellar record of wheels flying off - lately they've been way over-torquing wheels to avoid further fines and lawsuits.
Any way, question is: would an impact wrench make the changeover perhaps a tad safer? If so, which unit should I get? If it's just for convenience, then I'll stick with the manual tools as I don't find them that bad.
Thanks for any help!
