It might, but in the 20+ years of "extreme" wheeling I've been doing in Toyota trucks, 4Runners and now my 80 I've never had an issue..
I'll stick to going "commando". 🤘
I do appreciate the advice though.
I don't use any gaskets on axles. I use Black RTV on the 3rds, front hubs, and the rear axles.
Figure it'll keep all the water, sand and other crap out and the oil in.
