Opps. This isn't supposed to happen to one owner in the space of a week. I just found out in addition to my MDF problem I am now the dealing with either a transaxle or transmission problem. About a year ago I detected a dry crunching noise coming from the left front wheel area of my 2004 Prius, when I turned right at a stop sign. I took it to my dealership and they said it was a case of 'dry boot', which they lubricated. Still, the problem persisted. This week I took it in for an oil change and asked that they look again. They assessed it as a defective left transaxle. They ordered a new one and installed it. Still the noise persisted. They removed it. They then talked to Toyota super techs and decided it must be the right axle. Ordered and instlaled that and nope, still the noise. Now they are looking at the transmission. Very frustrating. There goes the gas savings for the next 700 years, unless it's a warranty issue.
