For those that have pulled the differential without removing the torque tube, how do you get it past the EBCM? I have the trans lowered pretty far but the top of the differential case is still smacking the EBCM. I am worried about lowering trans more because of the manifold/firewall clearance.

Unbolt the EBTCM from its mount and it SHOULD have enough movement/flex (on the brake lines) to be able to be moved enough to help clear the Diff..

Have you removed the rear cross member or dropped it down far enough to help let the diff drop more?

Rear cradle is out. I have the EBCM unbolted and it is un plugged. I can only push the EBCM up until it hits the surface above it (gas tank?). I guess I need to go lower with the tranny.

Pull the intake manifold off and you can lower the drive train a little more... Be careful with the big wire harness above the bell housing. As you lower it have someone keep an eye on that harness.

Or maybe loosening (not removing) the front cradle nuts so it can drop down about 1/4" to 1/2" or so. Since everything's this close, it might just be all the extra clearance you need.

Caution: Do NOT use any impact wrenches on the cradle nuts, either front or rear. Hand tools only on these.

Thanks for ideas! I found a complete Z06 differential which I think I will buy instead of adding the z06 parts to my original differential. Not planning on being at the dragstrip much so I think this may be a good solution instead of adding 300m or z06 output shafts.

You have to loosen the bolts of the torque tube at the bell housing behind the motor. Also watch the rear of motor didn't hit the fire wall or it can break it .

I was browsing through these trying to get some help on my clutch pack replacement, and no one seems to have done this with the diff on a stand. I was given some advice that if you want to avoid having to remove exhaust and tunnel plate, lower the tranny until the torque tube hits the tunnel plate, and while supporting the tranny, detatch the diff and slide back. The diff won't come off completely as it will hit the rear storage compartment, but it will detach enough to slide the carrier out of the housing if you turn the housing slightly.

Skipped a lot of steps, the bolt plate has to be removed, passenger side cover, and of course rear subframe dropped, etc.

Hope this helps.
