Look around. Some one has posted up .pdf files of the repair manuals, and you could get the information there. You can torque the lowers any time, but the truck should be on the ground with all the weight on it before torquing the UCA bushing nuts. This will leave the rubber part in a neutral position. If you're up in the air and tighten them, they will be stressed by the extra twisting.
