Sealants: Rear Axle Seal Install & Axle Tube
Have spent about an hour reading various posts, manuals, etc. on installing the rear axle seal in the axle tube per picture below (not mine, just grabbed off BB).
Seems some people use Permatex Ultra Blue between the outer seal housing and the axle tube to make sure it doesn't leak there. Some use grease there. Seems some don't use anything. I was thinking of using some Permatex Anaerobic (51813). What's the best practice here?
Also, I assume Permatex Anaerobic gets used where the axle tubes mate with the differential pumpkin, correct? Manuals don't mention it, but I see it some posts.
