ok so again i'm not really sure what's going on, but at least i have narrowed it down alot from my last post. Front diff is good, center diff is good, but rear diff is giving me the grief. I have pulled out and refilled the diff 3 times now, so it is put together properly and spins fairly well out of the chassis. The rear hubs spin nice and free when out of the diff, but when i put the shafts in the rear diff everything gets near impossible to turn with fingers, and on both sides of the diff. I don't know what i did, but the rear diff in the chassis is giving me grief, and i don't know what to do because it should not be this tight

If you can post so up close pictures that will give us a better idea of what is going on. I would take pics from the very back and sides of the car.

Any chance you got the front/rear shafts mixed up ? there is a 2mm difference between front/rear.

one of my first thoughts were the driveshafts, but they are 96mm back and 94mm front. Here are the pics

-Is the flat on the drivepin on the centre cvd lined up with the grub screw?
-Did you use two grub screws on the centre driveshafts?

Pull the outdrive covers/sleaves out (should be about flush with end of outdrive).....looks like they may be pushed into the 'shell'. Also check for any flashing etc on it that is left over from the molding/parts tree.
