Something I learned today, Need advice.

Actually, your rear axle bearings are sealed. They don't receive any oil from the rear end (unless the axle seal leaks!) and, for all intents and purposes, are not repackable. If the bearing is making noise, it's bad, and repacking it won't repair it. the first thing you need to do is verify that it's the bearing(s) that are making the noise. I'd get the car securely up in the air, pull the rear drums, fire it up, put it in high gear and listen for noises. A stethoscope (sp?) works the best but a wooden dowel will work also. Just be carefull with all the spinning shafts so you don't get hurt. If it's only noisy with the drums and wheels on it, it's not likely there is a bearing problem. If it's making noise with drums and wheels off, try to isolate where the noise is coming from by moving the stethoscope around to various spots on the axle housing. When you find the loudest area, the closest bearing is usually the culprit. Take your time, don't rush to judgement, rear end noises can telegraph around. Sometimes it's only a subtle difference in noise from bearing to bearing.
Repair is relatively easy. The kit shown above it is a good way to go so you have all the parts you need. If you don't have a press, get one or hire a machine shop to do it for you. Other than that, and a slide hammer, you really don't need any special tools. If you choose to take the old bearings and lock rings off yourself, be carefull you don't damage the seal surface on the axle shaft. If you gouge that area it will never seal again and you'll need to get another axle shaft.
