Steering All Over the Place at 55mph+

Looks like the old bushing shell. You pulled the old bushing guts out of the outer shell.

With the puller tool that probably means you needed a larger washer on the inside to capture the outer shell and pull it out
If I can't get it to budge with the puller even with heat. Hack saw, torch, pliers... those old ones are welded on the control arm with rust. Gave it a shot! Passenger side removal tomorrow then time for new UCA's.
