Front end wobble

I have not done anything to the brake system. Reason being that I had plenty of pedal pressure before unbolting the caliper. And the tire was fine. Could it be that the new half shaft is out of balance? Seems unlikely. I am wondering if something is out of whack from the joint grenading while cruising at bout eighty five mph. But that seems unlikely as well. It broke the outer joint which is pretty forgiving in my experiences. I am baffled at this point.

Caliper was not damaged nor was anything hit when it broke, the boot held together and I triple checked all my torque pecs. Forgot to mention that I only separated the upper ball joint, caliper bracket, tie rod end, and sway bar link. All were in good shape. I greased everything as well. Would over-tightening the sway bar give me a wobble? I figure not, but figured I ask for an opinion on that as well. I am starting to think the clip on the stub shaft was in disrepair, even though after inserting the half shaft. I could not remove it by hand maybe the shaft is moving in and out but then again the a arms are good, and bushings good. The car is solid as can be. What is more, would unplugging the ABS have anything to do with the loss of pressure? Trac light came on when it was not before.
Thanks for all the insight guys.
