Power steering pump, Rack n Pinion Steering Gear, Water Pump, etc

Which is the part you have a problem with? the list of parts? Or the price? If you don't trust the diagnosis keep letting different shops look at your car until you get the answer you want. Did the independent shop come up with the same list of parts that needed replacement or did you just give them the list from the dealer and get an estimate from that. As to my recommendations I would always go with a trusted independent over a dealer.
