Several times in the last few months when I have accellerated a little harder than normal (but not every time), I have gotten a metallic sounding chatter or chirp that seems to be coming from the right front under the hood for just a few seconds. The sound reminded me of something from my distant past from either a slipping manual clutch or a loose motor mount. Does this ring a bell for anyone? The dealer mechanic is thinking that it could be a TC problem or a common Liberty rear brake problem.

Thanks in advance.

Probably not related... but mine makes an odd noise in reverse. It makes a whining noise like a brake is stuck or something for just a second or two when starting to move in reverse. Anybody notice that on their CRD?

I have the "turbo bark" when you let off the throttle quickly after hard acceleration, but more disturbing is a whirring/chirping sound coming from the engine or tranny when accelerating at 1/2 or more throttle, between 2200 and 2400 rpm. It will go on as long as I hold the rpm there and go away completely on either side of that rpm band. Can't say for sure what it is, but I try to avoid holding the engine speed there for long.

I get this chirp or squeek for a fraction of a second during upshift with medium to hard accelleration. It is kind of a metallic sound a bit like the sound you hear when the ESP kicks in. I thought it might be that the transmission bands momentarily have slippage . Not enough hydraulic pressure to produce crisp shifts? Pump almost shot?
I haven't gotten the F37 done.

Yes. I had it. They put on new rear pads and rotors and that stopped it. That was 14000 miles ago.







Also, for the rest of you, DCX has asked the techs to do a check before performing the F37 to see if there is a chatter which may be TC related. Supposedly if they hear it, then a new tranny pump is needed along with the TC.

Have you done the F37 yet? If so, did this tranny condition exist before that?

This is exactly as I have described in other posts but mine occurs between 2000-2500, then the vehicle moves slightly more freely. I really theought it was the turbo but today the dealer replaced the turbo assy. Result...It's the same as it was, no difference, the dealer has acknowledged there's a problem but now has given up and can't fix it. They have seen this with 2 other CRD's but not to the extent of mine. They said I should contact DC direct if I want more results? That's it, they gave me the keys and I left, only to drive 50 feet, turn around and head right back to the dealer to point out that the parts changer miss aligned the exhaust pipe to the turbo and there's a new low growl with huge whooshing sound! The tech writer comes out to look and say's "ya I can smell exhaust"...DOH. He goes on to tell me come back tomorrow and we can fix it up.
That noise has progressivly been getting worse over the months, to the point where it does it all the time and getting louder under any load but being loudest going up steep grades at 60 KPH. I firmly believed it was the turbo, but not so sure anymore as it was changed. It could be the TC but I doubt it, that blasted noise is right where the turbo lives.....I'll try and talk with the manager tomorrow about options.
