Wheel Lugnut Torque?

Hey guys i just got my wheel alignment done and it runs a lot straighter. Only thing is he said my front left [opposite of which side took impact] wheel bearing had a little bit of play but its ok for now, he said just to keep my eye on it. Anyways what is the specific wheel lugnut torque for a 96 cav? Is it neccisary to have them at that exact torque or can you just torque it down real tight until it doesent move anymore? Because for example when u need to swap a hubcap or w/e u need to take them off and I just tightened it till it was very snug. Thanks

100 FT-lbs

K thanks, wheres the best place to get a torque wrench for doing these? Ive never used one before but I know how they work. So it is neccisary to have it at 100 ft lbs? Thanks

I just turn the lug wrench and put all my weight onto it until its really tight :) Never had a problem yet!
