i picked up a 1/2" mastercraft toqrue wrench for 79.99 at canadian tire.....it was on sale, so why not.

now that i have this wrench, whats the proper technique for using it? i tried tighting my wheels, after mounting summers on, and heard a lot of "clicks" after i set the dial to 72 lb/ft. how do i distingush the "right" click?

the reason i went with a torque wrench was to avoid warped rotors.

No instructions? First, set the torque. Use a smooth, kinda slow, not jerky motion when tightening. when the wrench reaches the specified torque, it will click and appear to slip. This is the right torque setting. Normally you use two or three settings rather than the specified one. If it says 80 ft-lbs, start with 60, then 70, then 80. This will cinch the fasteners up evenly. When I reach the specified torque, I usually run around the bolts one more time to be sure. 72 ft-lbs seems kinda low. My Chilton specifies 82 ft-lbs for the lug bolts.

72? it depends. Where did you get that number? My car is 72 if i remember correctly and i got my number from the BMW owners manual that came with the car. That is the number I personally would go with. Look in the manual and you will see a section of specifications. Even though are cars are all E36 that doesn't mean they require the same torque. My dads 1995 M3 was like 81 lb/ft, where my 1994 325is(so same body basically), is 72lb/ft. Go by what is in your manual and you will be fine. The air pressure for the tires was different between my dads and my car too.

In my 95' manual on page 112, it says 80 ft-lbs. My Chilton says 82 ft-lbs. Not really concerned about 2 ft-lb discrepancy. Wonder what the difference is in the years?
