Brand new to tacos

I'm brand new to tacos and haven't done much with them, one of my worries is that I'll enter water that is too deep and I'll ruin the axles or the differentials by getting water into them or into the hubs and ruining the grease inside, how deep can you go with a stock Tacoma and no aftermarket axles?

 

You may want to look into the Diff-Breather mod.

Also, I wouldn't go in water deeper or taller than the door itself but that's just me.

It's not so much depth as how often and how long the components are submerged. If I went through 18+ inches of water fairly regularly, I'd change out the fluids AT LEAST twice as often as recommended. But I live in the desert...
