We're worse than women. Differential oil/grease smells like absolute shit. Like holy fuck, you guys don't even understand. Tore apart a rear diff in a yukon today and about threw up. Shit is fucking disgusting. It's one of those smells that draws you in because you're trying to figure out what it reminds you of but can never put a finger on it. It's like a mix between rotten eggs, shit, and something else. It's fucking ridiculous.
