I hope old broken parts are being replaced it new, not being welded back together. I'm as cheap as anybody, but you don't skimp on suspension parts.
If you want to get a strong welder for repairs, check out www.readywelder.com That's what I use and its a hot welder using fluxcore. You'll need two good batteries, but if you need to do any welding on-site it is worth it. In fact, I don't currently have a shop welder(no power yet). I just use the batteries. I'd bring it down on my trip but we're taking my wife's Honda Civic(diesel prices are through the roof, otherwise I'd drive my dodge ram).
