Well, there needs to be an accurate torque value somewhere out there.
FWIW, there are plenty of reasons to do this work yourself, as opposed to "Might be in your best interest and/or family and friends best interest to just pay the extra few bucks to have the work done at a shop." Even in good shops, things can happen, and I have experienced costly strategic mistakes even in reputable shops....
So, was replacing front and rear wheel bearings (hubs) and shocks in my '16 Expedition, using Motorcraft shocks. Unfortunately, Motorcraft does not market a quick strut for this model, so I am forced to replace the shock separately, with new mounts, insulators, shocks. On the front, the shock attaches to the lower control arm with two bolts through the lower control arm, and even after searching, the most reliable torque value for this shock to lower control arm that I could find was the Chilton value of 406 ft-lb. As I was torquing it to 300 ft-lbs, the bolt sheared off halfway down. Clearly, this smaller bolt is not meant to accommodate a torque of 406 ft-lbs. The rear shock is different, with a single through bolt which will no doubt handle 406 ft-lbs.
As for me, I guess I will trust the lower 86 ft-lb value and LocTite that is listed for the 2nd Generation Expeditions......
