A what noise does it make when you actually drive the car?

Drivetrain noise without out any load on it, when on axles stands, is quite normal.

In gear at idle and slight throttle no noises. Gently accelerate and a loud grinding noise comes from under the car. Canít tell if from the rear diff or transfer case. Sounds like two badgers fighting in a steel drum.

Could be front diff bolts that are loose/come out?

Thanks for the help guys. It was the rear diff. To much backlash.

Iím guessing the noise wasnít there before, but then started to make itself apparent?

My question is what causes the problem with the ďrear diff backlashĒ? This is the first time Iíve ever heard it mentioned.

Is it something that in time needs adjusting? Iím just curious if itís something I need to keep an eye out for, or ear.

That I canít answer. I did a CK Lancer to Evo 5 conversion. I bought the Evo from japan as an ex track car. So was expecting some problems. You can check the build in the project section.
When the car conversion was done was the only time we got to drive it and that was the problem we encountered.
I started tearing down and servicing from the gearbox to the rear diff.
Surprisingly every thing but the rear diff was like new.
While I was servicing we changed clutch and the 4 bolts in the transfer case diff.
As for the rear diff I have yet to open it to see what is damage inside. Got a replacement off a low mileage evo6. The guy was going rs.
