3/4" Torque Wrench
You need a Torque wrench that provides 100 ft. lbs. setting. This is the Harbor Freight one I use.
3/4 in. Drive Click Type Torque Wrench. Pittsburgh Professional - item#808. 3/4 in. torque wrench provides a range from 50 to 300 ft. lbs. Only: $89.99 Sale: $79.99
It was a sale price of $19.95 free shipping when I bought it, at their current price you might as well just pick up one at Home Depot or Walmart. While you're at it, go ahead and get a cheap set of sockets, then you are set for torqueing your wheels too!
Here's the link for the Andersen WDH Installation Manual. It references the 1 1/4" Socket that's included in the package.
