Lower Control Arms Stamped, Forged, Welded?

[czycoot1318]

I am unsure whether or not the lower control arms on my 98 silverado z71 are stamped, forged, or welded. I am replacing the lower and upper ball joints and need to know, but I can't tell for sure. Can someone help me out? Thanks

On my screen, looks like welded

That's what I'm leaning towards from the second picture...

Thanks..I had the same question about my truck..welded versus forged. Before I dive into this project, about how many hours of work should it reasonable take to replace both the upper and lower..per side?
