That's the life with these old trucks. They're getting to be senior citizens now. Your truck just seems like it's been neglected over time, which is very common.
That tie rod end is an accident waiting to happen. It could kill you or anyone else at the drop of a hat. Get yourself a new one ASAP, and when removing the old one, mark the threaded portion with duct tape, or a paint marker, etc.. That way you can thread the new one on to the same spot and it won't affect your toe-in/toe-out as badly. Many people skip an alignment after replacing them if the truck doesn't seem to need it, but an alignment is recommended in most circumstances.
As for your wheel bearing, it looks shot as well. It's been a looooong time since I tore in to the front of a 4x4 Ranger from that era. I'm not sure if some of the parts in front of that bearing are part of your 4x4 hubs or not. Do you have auto-locking hubs, or the type you have to turn the knob to engage the 4x4??
If you remove the brake caliper, you'll be able to see how much play is in the wheel bearings. The brake caliper is essentially holding it all steady. Just be careful when removing the brake caliper, because you can easily ruin an old rubber brake hose by bending it too much, and NEVER let the brake caliper hang by the hose. Use some wire to tie the brake caliper and hang it by the wire.. Then you can try to wiggle the rotor.
