Rear Axle seal concern prior to cross country drive?

[BassCatsBeerandDeer]

Hello Gents. taking a look around the truck prior to moving cross country and noticed a oily residue build up around the rear passenger axle. take a look at the attached pictures and let me know what you think if this is permissible for future maintenance or in more dire need of maintenance/replacement. left side attached as well for reference.

Yep, sure looks like you gave a rear outer axle seal gone bad. I'd at least check your axle gear oil level before the travel and fill it up, as I'm sure u don't know how long it's been leaking.

Checked the read diff oil, looks just barely below the fill edge and very clean so very minor leak that has occurred over the past 100k miles, ill keep tabs on it cross country
