2016 2500 10.5 14-bolt Torque Specs

[cire0309]

Couldn't find anything in the search that mentioned the torque specs for the bolts on the rear cover for the 10.5 inch 14-bolt rear diff.

 

I know the drain & fill bolts are 24 ft-lb. and I've found different torque numbers for the bolts on the rear cover. Anyone have the torque specs on these bolts? TIA!

Drain is 24 ft.lbs.

 

Fill is 55 ft.lbs.

 

Cover bolts are ONE TIME USE must replace them.  New bolt torque spec is 30 ft.lbs.

 

Brake hose nut is 18 ft.lbs.

Much appreciated!

 

Is it common for fluid to slowly weep from around the cover?

I'd say no unless the gasket is failing or if it wasn't torqued properly if someone had it off prior.  Or if the vent is plugged for any reason and its pushing fluid.

Cover hasn't been off, I'm the original owner. Where's the vent fitting located?

Passenger side of the housing just inboard of the right hand axle tube.  Should be a threaded in nipple with a hose attached to it.  That hose routes all the way to the fuel filler neck and the vent itself is at the end of that hose tied to the filler neck.
