Ball Loosened, Use Loctite?
From time to time my son or I have to tow bar his 1946 Chevrolet 2 ton rack truck. He uses it for his food catering business. Being it is old it breaks down once a year. So when booked to do a p...

Wow. When I used to do torque wrench training (I did a lot) I would use a torque stick to demonstrate the effect of wind up with extensions and accuracy. I would use a digital torque wrench on the input side of a torque stick that was attached to a transducer and digital meter. The torque stick would indeed wind up and limit the output and there was no impact wrench in the room. This was all documented by the peak hold functions of the equipment.
One of the first rules of good torque wrench technique is to secure your work. Chock your tires when tightening lug nuts and support your receiver if using it to tighten your hitch ball. Simple physics.
A torque stick may well limit the output torque and a truck suspension would work similarly, but ONLY if you get the rear wheels off the ground. Then and only then will you no longer be able to apply a higher torque. Until the, when the amount of torque applied reaches the setting, it will click and you're good.
All the suspension of the truck does is cause you to have to travel the wrench handle further to build the needed torque. The torque wrench simply clicks when the required torque is applied to the drive end and it doesn't care what resists the motion on the nut side of the equation.
That said, preventing movement can still a good idea if you're having to lurch the wrench as the transient torques involved will cause false readings. The same is true if you yank on a torque wrench even with a stable platform.
