Got the U joints changed in the front driveshaft. Found one that had a broken bearing cap, no bearings and was completely dry. Figured that was definitely the problem. Got it back together went for a test run and all bad vibes are gone!! woohoo!! Of course my check engine light decided to come on so I will have to figure out what thats about. Didn't mess with the diff lock yet. Didn't want to get spread out over too many fires. When the weather warms up for good I will get to looking at that and try to loosen it up. Thanks everyone for the help.
