I hope someone can help me, I'm new to this page. I've got a 2005 RX330 AWD with a right rear wheel bearing on it's way out. I find this step-by-step very helpful and would like to give it a go since the Toyota Dealer quoted me $1,000 to do the job. My question is which bearing assembly do I need? When I go to parts geek via the link above, there is a meriad of options. Some say rear FWD, some say rear AWD, some indicate right or left specific. Also, they range in price from less than $100 to nearly $400. Can someone help me? Should I avoid the cheap bearing assemblies at all cost? The car DOES have 150,000 miles, so maybe the cheaper bearing is reasonable? Help. Bob
