Thank you both. It is the alignment. 2" off in the front of the tire and 4" off in the rear. I now have it adjusted within 1/4" and it is driving kind of normal. Thank you again for taking your time to answer my question.

I snapped a tie rod on my 2018 Defender HD10. Had it repaired. Now when driving it on a dirt road at or above 15mph, the front end "jumps" left and right. The jump is significant and unsafe. What is wrong with it?
