I finally found a local shop that uses a hand torque wrench to finish the lug nuts. They have a chart on the wall, and as I watched the mechanics all dutifully walked over to the chart and looked up the proper torque for the vehicle they were working on. No relying on memory, they actually looked it up. They also replace all rubber valve stems with metal without my asking, and use metal caps instead of the cheap plastic ones. This shop is a keeper.

Unfortunately, they do not three-step the torque like the manual recommends. So when I get home I redo them myself.

An old-time grizzled mechanic once told me an overtorqued nut will loosen before a properly torqued one will. I have not tested that theory, but it sounds logical. As a bolt distorts from over tightening, not all threads will be fully in contact with the nut.

Checked today. Then went to the big box hardware store and bought a 1/2" drive 13/16" deep well thin wall six point socket. (I already have a 1/2" drive breaker bar and cordless 1/2" drive impact driver.)

How much torque does the impact driver develop? Where is your torque wrench?

The impact driver doesn't develop much torque at all. It is only 18v. If I have to change the tire on the road, The impact driver will seat up the lug nuts and I will use the breaker bar to snug them firmly. For over 40 years, I didn't have a torque wrench. I never had a tire fall off.

I think it is responsible to tell newcomers that come here to do it correctly. "Snug them firmly" is not the recommended torque specification.

When we picked up our new TT at the dealer, the sales guy came out with a Home Depot Ryobi impact driver. He was going to tighten up all the nuts on the dual cam WDH and ball to get us off the lot faster. Impact drivers must have LOTS of torque... [emoticon]

I had taken a torque wrench with me and had to ask him to kindly step away from the TT please. [emoticon]

I wonder how they put customer's wheels back on in the shop when they do service work? I do know first hand that they can't even properly tighten a #8 wood screw.

Actually, impact drivers generate up to about 2,000 in-lbs ( 167 ft-lbs) which is pretty darn high for a battery operated device. For a number of reasons, not appropriate for automotive and related work. Excellent for house framing with construction screws. I framed a large house with one and would never go back to nails. I saw a mechanic on one of those car restoration shows use an impact drive on a customer's lug nuts. The boss found out and gave him [email protected]#$ and nearly fired him.

Our double ram bottle jack does (it's about 7" tall collapsed).

I am considering getting a cordless impact driver in the event I need to chang a tire on the road. Any thoughts which ones seem to be most reliable? I have a torque wrench to finish them off.

Impact wrenches should be used only on the lowest impact setting to run lugs back on and only until the lug is snug. If your torque wrench clicks before the lug turns you already over torqued it!
