I just wanted to thank everyone for their help. I bought a nut wrench for a GM with 6 teeth on it, grinded off the 4 i didn't need and it works fine. The diameter is 2 1/2 inches for anyone who wants to know. Also, I took off the lock nut, without taking off the hub, just to made sure it fit and to see how it worked. My brother is the one who needs it, and since when he comes in he only has limited time, i wanted to make sure it would work for him. Would I have to tighten it to 145 ft. lbs then loosen it to 0 ft. lbs, then back to 18 ft. lbs? Because at the time, i just tighened it to 18 ft. lbs. Just curious if i had to proload the tension if I didn't take off the hub assembly. Thanks.
