I tried searching for this but didn't find anything. I'm not a mechanic so I will describe what I'm doing as best I can. Basically, I need to know what to torque the stud/bolt to that connects the upper control arm to the frame in the rear of the truck.

I'm installing wheel-to-wheel running boards on my new-to-me 2019 Ram 2500 6.4L crew cab and I had to loosen the stud (bolt) that connects the rear upper control arm to the frame (see pic) so that I could slide a bracket underneath the head of the bolt. The opposite end of this control arm connects to the axle. The bolt I'm referring to is located just in front of the rear wheel and uses a shackle mount to connect the control arm to the frame. I need to know what torque to re-tighten that bolt to.

Also - I think I have the correct torques for the A, B and C pillar cab mount bolts but if someone could confirm, I would much appreciate it. I read the the A and B pillar cab mount bolts to 80ft lbs and the C pillar to 85 foot lbs. Is that correct?

and yes, I'm ordering a service manual. Guess I got a little excited and got ahead of myself here.

 

Correction - I should have said the rear LOWER control arm NOT rear UPPER control arm.
I think the bolt in question is called a hex flange headbolt

 

Dealership service department should be able to tell you. Worst case, go in and see 'em, and ask to see the body manual for your truck. (where ever the suspension section is. )

 

ok, thanks.
