Hello fellow DSMers, I'm having an interesting chatter noise on low rpm 1st-4th at 2k rpm. I have a new shep stage 3, with 3k miles, stock t case, rear diff and carrier bearings (probably original) it's not the motor because this sound hardly exists when warm and is not there at all upon decel or hard accell. It sounds like it could be the t case, carrier bearings, or rear diff. I can't recreate the sound when stopped either only during a roll and light throttle when the exhaust is still quiet. I'll get a second video of it, but on my dyno video in the beginning you can sort of hear the chatter. Checked with stethoscope and can't pin it because it needs to be rolling. It COULD be a harmonic vibration but something tells me thats unlikely. Everything in my car is tight.. I'll see if i can link the dyno vid. In the beginning jeff bush heard it and asked if it was a new
Motor. I told him it has 7k on it and he left it at that. Any help appreciated this is really annoying.
Edit: looked over the video and the video is cut right before the sound started I'll get another video. I hear it quite well in my parking garage.
If it is a t case or rear diff is there any way to check these while they are in te car? I have no problem taking the transfer case out if need be but i have never removed the rear diff,
Rear diff fluid never looks too good when fluid is drained either. But it's old.
