Cab mount torque spec
Anyone know the torque specs for front vs rear mounts on a 75 c10 2wd? Can’t find it in the books.

Re: Cab mount torque spec
I never looked it up and I just crank them down nice and tight with my 1/2" breaker bar. I don't want them to ever loosen up and wear the holes or just squeak. I have a Caddy Seville that the mounts keep loosening up on me and I have to tighten them down every year or two. I don't dare to use thread locker in case I need to work on them someday. I just like 'em tight I guess.

Re: Cab mount torque spec
We found it in the manual. It's at the back of the service manual with the other torque specs I've checked before, of course. According to the manual they're 45 ft lbs front and rear on this truck. I'm using rubber mounts from LMC.
I torqued the mounts without any additive on the threads. Torquing bolts to spec with anti-seize will usually result in over-torquing because it lubes the threads. And threadlocker isn't needed on mounts. Anybody want to opine on how close is good enough in terms of squaring a cab to the frame? Within 1/16"? 1/8"? I didn't find any spec in the manual. FWIW, I think I'm around 1/16", which probably means I'm really around 1/8" due to user error with the tape measure, etc. I guess I'll know how good or bad it is after I hang the sheet metal.
