Was just looking at another forum and found the following. Although it came from another brands manual it is a good process / procedure to follow for your torquing the lug nuts. Also, per this same site I see that the 1/2in stud takes a 7/8 in socket. The larger 9/16th stud take a 9/16th socket as I recall. Be sure to get the heavy duty ones because you are going to torque them fairly high.
Wheel Reinstallation After removing a wheel from your RV for any reason, you must carefully follow a 2 step process: 1. Wheel Reinstallation 2. Follow-up Step 1) Wheel Reinstallation During wheel reinstallation, the lug nut torque must be applied in 3 stages. This will ensure the wheel studs are centered in the wheel holes, and will help the lug nuts maintain proper torque. Start all lug nuts by hand. Stage 1: Set your torque wrench to 20-30 ft/lbs (50-60 ft/lbs for 9/16” stud). Begin with the appropriate bolt for your wheel (12 o’clock position for 8 and 6 hole wheels and 2 o’clock position for 5 hole wheels, as illustrated) and apply torque to all lug nuts following the star pattern indicated. Stage 2: Increase your torque wrench setting to 55-60 ft/lbs (90-100 ft/lbs for 9/16” stud). Begin with the appropriate bolt for your wheel and apply torque to all lug nuts following the star pattern indicated. Following stage 2, the wheel can support the weight of the trailer and can be lowered off of the jack stand. Stage 3: Increase your torque wrench setting to 110-120 ft/lbs (140-150 ft/lbs for 9/16” stud). Begin with the appropriate bolt for your wheel (as illustrated) and apply torque to all lug nuts following the star pattern indicated. Step 2) Follow-Up: Retorque after 10, 25, and 50 miles: 1. After the first 10 miles of your trip, pull your recreation vehicle off the road into a safe work area. 2. Set your torque wrench to 110-120 ft/lbs (140-150 ft/lbs for 9/16” stud). 3. Begin with the appropriate bolt for your wheel and apply torque to all lug nuts following the star pattern indicated. 4. Reapply torque (at 110-120 ft/lbs or 140-150 ft/lbs for 9/16” stud) and repeat steps 1, 2, & 3 again at 25 miles and at 50 miles of your first trip. The follow up process is complete and you should refer to the general lug nut torque maintenance process described in “Pre-Trip Maintenance”.
Hope this helps.
