Yeah, I'm pretty sure that's for rotating the inner tie rod when adjusting toe, not for replacing the inner - though I do love purpose made tools.
I do a lot of track days and racing, so my toolkit is usually pretty minimal since I don't own a semi to haul my tools over. My rule is usually "make do with what you have twice. If you're still swearing the second time, go buy a quality dedicated tool and find room in the mobile tool box".
Oh yeah for sure. I'm just a home gamer and I can't stand jumpsuits, so any axle grease or bearing grease turns me into a spec ops camouflage expert.
I'll re-shill tub-o-towels here. Seriously fucking awesome for getting the even most sticky grime off your hands before you touch any doorknobs (or to clean your hands when there's no faucet around).
