1996 4x4 3.9

I'm riding home today when my wheel hub broke unexpectedly. Sucks. After getting towed home, I'm off to Autozone to pick up a hub. Anything else I should get just in case? I didn't really get a chance to look up under there too well since it was dark and rainy. I shined the flashlight long enough to see bearings was about the extent of my diagnosis.

Also, I left the left axle assembly off the truck since I need to repair the control arms and didn't want to take it off the axle again. Buddy told me it shouldn't be a problem riding like that since I won't be engaging 4x4 but that was the side that broke off. Coincidence?
