Is Impact Wrench Proper Tool?
 
I've recently ordered (delivery in late February) a freightliner
sportchassis medium duty truck (22.5X8.25 10-bolt wheels with Michelin
XRV 255/80R22.5 14-ply tires) to tow a trailer while I'm retired and
fulltiming in the RV. The truck has air brakes and air ride and
includes a quick disconnect fitting with hose for a tire inflation kit.
With this set-up I thought it might be a good idea to pruchase an air
impact wrench to periodically check/tighten the lug nuts on the truck
and trailer. However, after the research I've conducted (this is a
VERY confusing topic for a newbee) I'm not so sure this is as good an
idea as I thought. I do not anticipate using the impact wrench for any
other task. Other maintenance I do I can handle with my ratchet,
breaker bar, and/or cheater pipe.

Is an impact wrench the tool I should be considering?
If so, would an Ingersoll Rand 1/2" or 3/4" wrench (model #?)be
correct?
Or, is a good torque wrench a better choice?
Any assistance will be greatly appreciated.

An impact wrench is fine for taking the lugnuts off.
To put them on use a lugwrench and then a torque wrench.
Tighten lugs in opposite pairs.

Using an impact wrench to put lugnuts on is characteristic of
mechanics in a hurry at tire shops and brake&muffler joints who really
don't give a damn. If you care enough to check lugnuts, use a torque
wrench.

Whether you should put grease or anti-sieze on the lugs is a subject
of vociferous controversy in automotive mewsgroups. I always do.

your impact will not have enough power for you truck lugs. the proper
torque on most alumun wheel 22.5 tire wheels is about 450 ftlbs we use a
torque wrench to finish torque them all. KB

For many reasons, a torque wrench. Torque specs should be in the
owners manual.

No. It's probably the least suitable tool you'll ever need for that job.

A torque wrench would be the right tool if you're particularly pedantic about
wheel nut torque settings but most people manage perfectly well doing them up
by feel. In fact that isn't true. Most people manage perfectly well by never
checking them in the first place. After all, when was the last time you saw a
car sailing down the road on three wheels being overtaken by the fourth?

Stemmens Freeway, Dallas Texas, truck lost entire wheel/tire which hit
cement divider and went airborne to about 40 feet doing about 60 mph.

Truck tire/wheel is big and weighs a lot. Came down on hood of truck
just to left of me that didn't see it coming *(I did see it coming but
this only took a few seconds and had no time but to get out of the
way).

Check those g-damn wheel lug nuts, cause if that truck tire hit 1/2
second later than it did, it would have gone through the guys window
and squashed him like a bug.

There ya go. BTDT.

I wouldn't discourage him from regularly checking the torque though.
Most auto mfgrs. recommend one retorque of all auto wheels at some
interval after remounting them; I believe heavier trucks have regular
torque check intervals. This leads me to believe that proper torque is
more important on truck wheels than car wheels.

No, an impact wrench is not the right tool to check that your wheel nuts
are tightened properly. A troque wrench is the proper tool. Make sure that
when you do this, you follow the right ssequence. The impact wrench will
come in handy when you need to take the wheels off.

If you're just going to CHECK the torque, a torque wrench is the correct
tool and an impact wrench is dead wrong.

However, if I had a rig like that with on-board air always available,
I'd darn sure have a good impact wrench just for CHANGING tires! I hate
heaving on a lug wrench and use my impact for all my tire changing needs
in my garage. Also, smaller impact wrenches, butterfly impact wrenches,
air drills, and air grinders are a thousand times more useful than I
ever would have imagined them to be before I got a good compressor years
ago.

Loose nuts can be caused by overtightening. The stud has a
certain amount of elasticity, like most steel parts, and the proper
torque takes advantage of this to keep the nut snug. Overtightening
stretches the stud beyond its elastic limit and strains it, making it
non-elastic and if anything at all, like temperature changes or
additional stress from heavy loads or cornering is applied to it, it
will not snap back from that and the nut will now be loose.
I spent nine years selling wheels, studs and nuts, and other related
hardware. We sold a lot of this stuff to shops that didn't use torque
wrenches, and their customers had more "loose" nuts and departed
wheels.
Rust stains can be a good indicator, but many wheels are
aluminum now and it won't show so well. Black stains are more likely
there.
