when installing the pml rear dif cover is thread sealent or locktite required?

 

I didn't use any. Recently checked the torque and still to spec. My guess there's plenty of the original locktite from the factory install in the holes to hold the new bolts.
I do recommend using a little teflon paste on the fill, check and drain plugs for better sealing, mine is weeping from these plugs.
