Well the other night I was under the car installing new springs. Since I had the rear tires off, I was looking and heard that, apparently, one of the reasons why there is squeeking coming from the rear is because the e-brake cable is rubbing against one of the holders/carriers (or whatever you call them). I noted that this was the case as some of the rubber was wearing down. So I shot all four of the holders with some silicone lube and haven't heard a squeek since. But it has been a couple days since--however, it has been raining here and I don't think it has been washed off. We'll see. FYI for those that are being bugged by some rear end squeeks. Uh, from your car.
