Hi All,

Went to buy lower ball joints for the truck today. Went to Napa and they asked me if my lower control arms were welded or forged? I didn’t know so I checked somewhere else thinking it was a strange question to ask. I went to PepBoys and their computer asked the same thing.

My truck is a 1999 Chevy Suburban K2500 with torsion bar front end.

If I had to guess I would say with torsion bars the lower control arms are probably forged.

Anyone know for sure or how to tell?

Thanks,
Art.
