The main thing is to get the cones off. Some are threaded onto the axle and some are set screwed. Once off, the axle is fatter in the center to form a shoulder. Tap the axle end with a wood block and mallet to get the first side off, then put the axle back in to hit the other out.
Are the bearings worn or just need to be regreased? The seals are generally removable to allow regreasing. To remove, insert a small pointed knife or jeweler's screwdriver from the outer perimeter to lift the lip of the seal and pop the sheet out. Do not bend it or kink it, so gentle motion. Rinse with a cleaner such as Brake-cleaner let dry thoroughly and regrease with a good grease. The seals pop back on evenly and reinsert to the axle.
Some setups allow the bearings to be pressed back together via the QR axle and cones. It is not the fastest but is gentle and easy to manage by screwing the QR nut and flipping the lever. As it gets down to the end of the reach, add a nut large enough to shoulder over the axle end and continue the process until it is all the way down.
