Thanks Bob, I did tighten the shackles up, I'll check it out when I fill the tank. I have YJ shackles on and the YJ long bolts. I could back them off to 15ft lbs like you said and double nut them for safety.
I'm going to try that first b-4 I take the spring pack apart. Since I am out in the dessert now I'm going to see what loads I carry on the trail, then I guess I can make better decision. But first, I have to re-gear, I have 3.73's on the shelf and the front D-30 is already cut for a OX locker.
Just wondering w/the TF-999 and 3.73/33" or (32" now) tires it will be bad on fuel unless I get a 4spd. Going to try out the auto behind the 360 but I have a spare T-176 in the garage.
