On a scale of 1-10 my dad said it would be a 7-8 install but he says he's not familiar with Toyotas. He'd have to see the rear and look at it. I'm sure he'd be willing to help some. Best thing is to get a manual like Haynes. He said it should show you how to put it in if it's the wheel bearing. Don't go slapping a new part in unless you know for sure that's how it is. They're not the best books but they give you a good starting point. You just need to MAKE SURE that's what it is.
