just went through pages and pages of info for the sc400 power steering pump... I don't think they are the same so someone please help me out here. Seems my bearing/pulley assembly is messed up as there is loud chucking noise like a old train but no leaks. About to order one from carson toyota and it doesn't come with the reservoir. Is there O-rings/gaskets/parts I'm going to need in addition? Forgot to ask curt but do these pumps generally come with the pulley? Thoughts about Reman units from RockAuto? Any advise for the sc300 would be appreciated.

thanks
Charles
