So it seems that I'm one of the fellow drivers of a LS with a noisy rear. The car makes a humming, thumping type noise at high speeds (almost like the noise you hear with the back windows down). I bought an '05 LS used with 28K on the clock. It had the noise when I bought it but I figured it was something simple, tires, bent rim, alignment, wheel balance, etc. Well I had all of that replaced, new tires, new rims, and several alignments and wheel balances (darn near told me to stop coming in). I kept coming back. After all of this the mechanics decided to take a ride with me and they heard the noise but since it crops up at 75mph Ford won't touch it. I even called Michigan, no help. Now at 40K and no better, no worse.
So I replaced the easy stuff. The car doesn't make noise when I sway side to side so I'm thinking its not a bearing so maybe an out of balance driveshaft? If you guys could provide ANY words of wisdom, votes of confidence, advice, I would be a happy man. Great car but I can't get rid of that damn noise!
