Hi all, well here it is Fall in western NY... and my A/C compressor starts that death grind noise!!! Turn on the A/C or Defrost and I hear metal to metal grind for a second...ughh So , a new compressor is in order right? From what I can find 2007 Expedition EL Limited with 5.4 and rear air... should use a YCC355... first... can anyone confirm that... I would hate to buy the wrong compressor... Second, looking on ROCKAUTO, and other sites... there are quite a few options.. Motorcraft, Denso, UAC, Fourseasons... Anyone got any input on ones to stay away from and ones to go with? There is a huge difference in price... do you really get what you pay for in a compressor? Also, what other parts are required to change when I do this... some say change the condenser.. but since my compressor didn't implode do I need to? Should I replace the Drier and Expansion Valve too??? Will probably change the belt while I'm there... but anything else necessary Thanks in advance for any input... I obviously know just enough to screw things up...not enough to insure they don't get screwed up!
