Reason for loose feel on hiway romp

My sleep apnea is winning
At over 40 or so car seems to have a tendency to kick left on a romp. It would happen suddenly and only underr power. I found that a bushing was loose in the control arm socket. Its been replaced once and was still in good shape, but wiggles freely in the arm. It was the front upper arm PS bushing, and i hope it is reason for issue. You guys think tigging it in would ruin (burn) inside rubber of bushing? best aftermarket idea?
Thanks
