I've gotten a couple of emails saying that lincoln vs. cadillac misses me. So, I figured I would post something, as I haven't in a long time. Took my 05 LS to the dealer to determine what the grinding sound is coming from the left rear. It seems the wheel bearings are going out. It isn't bad at this point, but it will obviously get worse the longer I drive it. Anyway, it seems like just the wheel bearings can't be replaced but you have to buy the whole freaking hub/knuckle assembly, which is $900. Insane! Here is the part #: 2w4z-5b716-aa. The cheapest I have found is right at $700 at Team Ford. They also said I needed a tie rod on the right side, of which they quoted me $177 for that part. Please tell me there is a cheaper solution to my problems. Has anyone ever tackled this job before? I did come across a couple of posts in my search but they really didn't help me.
