Review on XtremepowerUS Torque Wrench: Efficient Labor-Saving Lug Nut Wrench with Torque Multiplier and Cr-v Socket (Includes 8pc Socket Set) by Andrew Britton

I've always seen these things online but never used them. I'm a diesel technician doing some extra work. I haven't done heavy truck brakes before because I didn't have a gas air compressor yet, so I couldn't safely loosen nuts on heavy trucks. A good client wanted me to do brakes on his truck so I decided to pull the trigger on one of them. Open the box, put a 33mm head and grip on it. After a few full turns, the nuts were loose enough that my 1/2" stun gun unscrewed them quite easily. I did the brakes, put the nuts on and tightened them with a torque wrench. This was on a full size Kenworth tractor trailer. Pays for itself the first time you use it. I'll never have to forgo brake work again because I can't loosen the nuts.
