Thanks Acrad - no, they are not. It is a mystery to me why they do not show on a bunch of devices, I would understand one, but multiple??
Anyway - I watched another pair of videos (I can see the pasted Youtube stuff !!!) and torqued those bolts to 59 lb ft, same as on the comparable Toyota SUVs. I finished the repair and the pinion seal seems not to leak.
A few observations - when installing the gasket/seal below the flange that you bolt to the front propeller shaft there is some corrosion that prevents inserting that gasket, so it needs to be sanded/metal brushed very carefully before inserting, otherwise it does not want to get in because of the rust lip. Once this is done - it goes easy. Be very careful so the dust does not get inside of the differential.
Also - on all the videos it seems that people just torque the main nut to exactly the place where it has been before disassembling, and not to those 360lb ft - this is because you do it ONLY ONCE when you install a new set of parts - then when you disassembly and assembly again, it just has to get back to the original position. This is because there is some 'crush' element that crushes only once and needs the 360lb ft, that is my understanding. Any subsequent reinstallation of the nut does not crush anything.
