Can't drive past 30mph, got on freeway, and it kept pulling from side to side

What is your question?

So I recently got towed..he asked if it was AWD..I specifically told him it was..he put it on dolly with 2 front tires lifted..we drove a few miles and heard loud noise and I turned around and it was smoking..I guess from my bck tires? He then got out and put my my truck on 4 wheels lifted. I thought nothing of it even though but one day my od light kept blinking entire day..it stopped next day..then I notice I can't drive over 55mph on freeway without shaking. Now it can't drive on freeway at all ..when I drove 40mph on freeway it kept going from side to side..I can't drive past 25- 30mph now..I just parked it in driveway before it gets any worse..I tried to take to shop..spent over $700 in total had tie rods replacement but car still the same. Could that tow damaged my rear end ? I don't know what's exactly wrong with my truck.
