That works fine on a relatively new vehicle but one that has run in salt etc you'll save a lot of time if you remove the steering knuckle completey by separating lower ball joint and outer tie rod end ball joint and bring the whole steering knuckle to a bench to separate the hub/bearing. Soak everything with penetrant, loosen the bolts a few turns and try hitting right on the bolt heads. I also made a very sharp wedge from a chisel and rammed it hard on the other side to seoarate the hub. It will finally come apart then you'll see all the **** that was binding it due to an alumininum knuckle re-acting with a steel hub. Clean the hole and grease everything and fit new bearings

To remove the oil pan on any vehicle, first remove anything obviously in your way...starter, exhaust pipe etc. Then disconnect the engine mounts and raise engine to gain sufficient clearance between frame and pan. You cannot support the engine from under the pan so either use a fixture above the engine or put blocks between mounts and engine to support it. After all rail bolts have been removed, remember that the oil pump pickup will interfere with removal somewhat but pan can be maneuvered around it. Anything preventing you from getting the pan out will then need to be removed or moved as they are identified. Be careful when raising the engine that you do not break anything above it as it comes up.
