I have seen control arms with bushing holes that are too large. The solution can be as simple as, pounding the hole flange inward because bushing holes are extruded, forming a flange.
Another solution is to build up the hole with weld, then grinding to size.
Tack welding the bushing is tricky because the bushing's rubber cannot tolerate any heat or it will melt.
What did 'bearing inspection' reveal?
The front coil springs have rubber isolators on the top only. - Dave
