I assume you mean to ask how difficult it is to change the main bearings WITHOUT pulling the engine out of the vehicle.
Don't bother.
To properly replace the main bearings you need to pull the crankshaft away from the engine far enough to be able to put a micrometer on the bearing surfaces of the crankshaft. To do that you need to disconnect the crankshaft from the transmission AND pull the pistons part way out. Also, depending on the type of seal used, many rear main seals must be replaced by pressing them into place after the crankshaft is in.
Don't even try to replace bearings without first verifying the status of the crankshaft. It must be round and within tolerance. If the old bearings have worn there isn't much chance that the crankshaft hasn't been affected.
