Just replaced the noisy bearing on my a/c compressor i decided to leave where it was and see if it could be done as most forum sites recommend to unbolt and bring to top of engine bay its a fairly simple job leaving it mounted just awkward took me about 4hrs all up for anyone who needs the replacement bearing number for this model its 83A694CS30-J it also suits the following models hope this helps (i tried to up load some pics of changing the bearing but uploading kept failing will upload when i can work it out)
