Replace Rear Wheel Bearings
Need to replace the rear wheel bearings on a 2017 C6 coupe. I watched a youtube video on this and the person doing the work used red loctite on the bolts attaching the bearing hub to the spindle. He also said there was a TSB that said to use red permatex gasket sealer when installing the axle nut and to let it cure for 24 hours. My 2008 shop manual does not direct the installer to do either the loctite or the permatex. Can anyone confirm that either of these are required?

The gasket sealer on the axle nut is to help prevent it from coming ever so slightly loose. If you get a popping noise at some point, that's probably what it is. For mine I had to re-tighten them I believe twice before they finally stayed put and the noise never returned. Doesn't hurt anything, just an annoying sound when doing between forward/reverse torque between the shaft and hub, it moves just enough to make a noise.
If they're torqued correctly the bolts should be fine without red loctite, though I'm surprised they didn't use any at all. I thought those bolts came with some on it actually, but it's been a few years since I changed mine. I would have at least used blue though.. really don't want those coming loose.

I put the blue thread lock and hat to remove it later to swap to long studs result was broke two 1/2 inch breaker bars would not come loose, had to buy a 1,200 foot pounds capacity newmatic torque wrench, that worked just saying.
Torque spec is 240 lbs. The dry glue on there from factory is all that’s needed imo.

By dry glue, do you mean a new spindle nut comes with the coating already applied to the threads?
