Customer Question

My '03 ML (202,000 miles) has developed a chirping and odd little noise like jarring glasses at certain times. It's becoming almost constant now. Had the water pump and pulleys replaced, my well experienced mechanic was horrified when the noise returned a couple hundred highway miles later. Also it's loud when in drive, quiets down considerably when i put it in park. Someone else suggested torque converter? My first question: any ideas as to cause? My 2nd question: how long can it be driven this way - I was on a necessary 1200 mile trip after the pump replacement (thinking all was good). I have another unavoidable 600 mile trip now.

Hello. If I can hear the noise I can tell you what the issue is. Do you have access to create a YouTube video or wanna do a phone chat where we can skype or FaceTime ? Or send me sound files via the phone ?
