Chain problems

Hey everybody I have a 2004 4×4 500 automatic. Scrambler drive on street mostly no jumps nothing fun as of lately. The thing is last year we replaced my chain and my sproket because it was getting lose and had to tighten often but now we tighten even more often like three times more often it is real bad also front has wobble doesn’t matter speed but I like speed and it gets scary at times. Some of the things I have been reading are axle bearings? Or bearing carrier maybe front. Sprocket clip missing but does anything go with crazy wobble in front the hope is to fix some items this winter to have ready to pull toboggan any help would be great .also not little gal but the rear end does slouch pretty good when on would love not to replace alot but whatever to get it back to good running conditions
