Replacing rod/main bearings without pulling motor - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is it possible to replace the rod and main bearings in a 96 Vortec motor without pulling the motor? I have a 96 4x4 suburban that if I remove the front differential I have pretty good access to removing the oil pan. I don't think that replacing the rod bearings will be too difficult, but don't know how hard (or if even possible) it would be to replace the main bearings without at least pulling the transmission back to allow dropping the crank out. Can the block half of the bearing be "rolled" in without dropping the crank? I just bought this thing and it was getting antifreeze in the oil. Replaced the intake manifold gaskets and that problem is fixed. It runs good and carries decent oil pressure, but I have heard that antifreeze in the oil is hard on bearings and thought if I could replace the bearings without too much hassle, that it might be good insurance against future bearing failure.

TIA,

Randy
