Don't know about the rattle. Freaky.

Ask one of the custom Driveshaft guys to give a listen.

I'd like to see the inside of the new driveshaft coupler design, wonder if it's similar to a CV joint, if so, it would make sense. If that's the case your driveshaft may be sloppy if you jerk it around.

It's at the tranny. When I listen back at the diff. there is no sound but what is coming from up front. The popping COULD be from the U Joint in the middle. It's harder to pinpoint BUT the rattling is 100% coming from the rear of the tranny area.

Man I hope you find it and it is an easy fix. Mine is an LS3 and my center splines twisted at the center slip joint, didn't make any noise but was a bitch to get the stocker out of the car. If it is the shaft I used the Drive shaft shop one piece aluminium and have had no problems with it.

Man I HOPE it's just the shaft. Or U joint.

Is there a doctor in the house?

It isn't your drive shaft or u-joint.... that loud and obvious of a noise, you would see that drive shft flopping around...... that is in your transmission somewhere....

You don't notice an shifting issues, or lurching? Did this noise happen to start after a burn out out

I picked up a set and used them. Pretty cool. But I couldn't pinpoint the sound. The driveshaft was moving and the tranny housing just had no sound in it. I'd swear the sound was coming from the driveshaft. I put the needle on the spinning shat but obviously the spinning of the shaft made it useless to hear.

Driving is smooth as silk. Never a miss or hicup. Can only hear the noise under the car. I believe I've narrowed the klunking noise to just above my X-Pipe on top of the heat sheild. Isn't there a U Joint up there between the two shafts?

Anyway, I'l have to wait and just have a good shop diagnose it. I don't want to be buying new bolts several times.

So what is next??

mikepage0007 · 08-16-2011, 08:50 PM

pull the shaft and you will find the noise..

JusticePete · 08-16-2011, 09:01 PM

We could use a focussed listenting device.

It is old school, but it works. Place the point on the tranny and the rounded end of the handle to your ear. Move back by fixed points until you are out to the wheel hub. The noise we hear in the vid is loud so you will hear it throughout the process, but you should be able to isolate it between just two points where it will be louder.

Pull the shaft. It's all I can do. I'll know what to do after that.

My dad does that to listen for leaks in plumbing pipes. He's done that forever. LOL

I tried the stethescope all over the tranny where I could get to. I could hear the sound outside the stethescope better. Almost as if it were in the driveshaft it's self.

Darth_Emma · 08-16-2011, 09:27 PM

Did you turn the stethoscope on? Did you check the batteries?

When you listened at the back end of the shaft near the diff was it similar in volume?
