Just started noticing a "chirping" coming from the driveline under certain circumstances.

Most noticable at about parking lot speeds, as I'm coasting or slowing, I'm hearing a chirping sound. More prominent with the clutch depressed, and frequency varies with gears. Faster in lower gears, slows when in higher gears. Eventually stops when the wheels stop.

Obviously transmission/clutch related, at least seems so to me. Clutch functions perfectly and shifts are smooth with no binding or grinding.

Thoughts? Troubleshooting suggestions?

Thanks in advance for inputs.

Torque tube bearings maybe?

Brake pads?

CV joints will chip too, but they go with car speed not
engine speed.

Check the bolts that hold the clamp for the TT near the trans. Mine chirps a decent amount and when I tightened those bolts it when away. Then came back and repeated the procedure lol.

So if this works, there will be a video attached here somewhere.

If you turn the volume up good and loud you can hear the chattering/squeaking/chirping at the start of the video. You should be able to hear the noise stop when the clutch is depressed and return when the clutch is released. The video is shot in the garage at idle. (Oil residue due to oil pan gasket leak )


While coasting to a stop at a light or in a parking lot, noise is still present with clutch depressed, coasting in gear. If taken out of gear while still coasting, clutch still depressed, noise will slowly "rotate" to a stop.

Release bearing? Pressure Plate? Torque Tube?

Using my ****ty laptop computer speakers but that sounds a lot like the fifth gear rattle.

all of the above.... add rear exhaust mount ?

Would love to have it be as easy as tightening a loose bolt, trust me, but when coasting with clutch in the "ratio" of the sound depends the gear I'm coasting in. In other words, it chirps faster in first than it does in third. I would think sound coming from a loose exhaust mount bolt or TT bolt would be independent of gear selection.

Really appreciate the inputs so far! Keep them coming.

Gonna swing by a fellow 'Lister tomorrow for a little troubleshooting help.

ej i have the same noise as you!!! it all started when i put a solid transmisson mount in. i think its transmission or torque tube related. call me tomorrow when you want me to come over

After meeting with MooreBoost, he helped me do a little troubleshooting. Due to his experience and expertise, he was able to narrow it down to either torque tube bearings or something downstream in the tranny itself.

As mentioned above in his quote, he has a near-identical noise in his 951 and has had it for quite some time. So at least I have the comfort of knowing I'm not likely facing a catastrophic failure immenently!

Thanks for your time today, Kyle! Great meeting you, and look forward to get togethers in the future.
