Thats a hairy situation. Heres my thoughts and expeirances.
Ive seen a couple lowers and uppers come apart going down the road.
Either from the lower bj bore being wore out or the taper in the spindle wore or egged,cheap over torqed undersized upper bolts and over torqed castle nuts.

in either case you could lose a wheel and have a big problem.

Never a good thing and very unsafe.
also its difficult to mike the bore since its stamped peice and not perfectly flat all the way through. But mikeing the bore might show ya if its egged out at all.

The bore could wore out just enough that even a oversized moog might feel like it seated but really only have little contact too the bore and still not seat correctly.

Eye ball that bore real good for cracks.
if there is movement that you may not be able too feel a weld will start cracking the steel just beyond the weld.

I would replace that lower arm and b joints for safety sake.
Control arms are common enough not too replace it.
you'll have the piece of mind that it was done correctly and be safe out on the roads.

Also it looks like you might wanna check those wheel bearings looks like hot/burned grease running down the backing plate.
