For socket size, I will have to slide under the truck tomorrow and see. For torque my 2003 Chrysler shop manual says 235 lb/ft. It does not differentiate whether a 1500 or heavy duty truck, it just has one torque in the chart of torques at the end of the rack and pinion section of Chapter 19.
Edit: I just now noticed that you have a '96 model, this is the 3rd gen forum, not 2ed gen, so I cannot guarantee the accuracy of the torque specification for a '96.
