Tranny/axle or something grinds when accelerating

[DsmKid98GST]

This happened after a night of spirited driving. The car is driveable, i just have to accelerate in first and second gear slowly. I do not hear grinding in any other gear while accelerating. Although, I don't push the car or spool the turbo much. The car drives and shifts fine otherwise. Now for the symptoms.

When I start off in first gear, when I accelerate and let the clutch out there's a very loud grinding noise. The same thing happens in second, just not as loud, as i accelerate. I am able to make the noise not happen by accelerating very slowly. Also, if I were to tap the gas lightly in first or second gear there's a loud CLUNK noise as if the axle or something similar is jolting in the tranny.

We suspected it being the driver side axle that i previously had to replace, but after replacing it for the second time today nothing had changed in driveability. We also put new transmition fluid in it after replacing the axle, knowingly nothing changed except how smoothe the gears shift. A friend stood outside the car as i made the noise happen, it happens on both sides of the car but on the passenger side it is a bit louder than on driver side.

I am friends with a very knowledgeable DSM professional. I usually contact him with symptoms with the car and he usually nails it. He said he's never heard of a problem like this and has been working on DSMs since '92.

Before I go to his place and we tear it apart to find out the problem, could any of you give me options or even tell me if you've had issues like this before.

Thanks,

I just got off the phone with my friend and he was contemplating the problem be coming from the motor mounts or specifically, the roll mounts. Would this cause the noise i explained in my origional post?

Thanks,

It was the motor mounts, specifically the tranny roll mount.

Just a note incase anyone has this freak problem like i did.

I'm having a similar problem and hope this is the fix. I just had the U-joint replaced the guy who is working on it has described the noise coming from just before the u-joint, but not into the actual transmission. Just that cone part before it. I hope he finds this to be the problem instead. To me it sounds like a loud vibrating, but I suppose grinding causes vibrating.
