1988 Jeep Comanche shaking on road

I have a 4wd 88 Comanche that has a tremble while driving. It felt like it was in the front passenger wheel so I replaced the passenger side U joint and it still trembles. So I noticed the front drag links where loose so i replaced the drag links (inner and outer).It still shakes while driving. I dont know what else to do. It was hit in a parking lot recently but it was trembling before it was hit. After it was it I noticed my rear passenger tire was wearing strangely and it seems to have a knot. Can anyone help me?
