Another trailing arm thread - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I discovered a few weeks back that I needed new arms, the old ones were so rusted that I could see through them from the side. Being short on cash, but having a LOT of welding wire compelled me to repair the ones I have. I started by pressing out the bushings and drilling out the rivets to separate the sections. The rust had literally bowed the centers out as it expanded over the years. I hammered the lumps out and cleaned off all the rust with grinders and wire wheels. Then bolted the halves back together with 3/8" bolts and welded the seams together top and bottom. Then cut out a 3' section of rot in the center and butt welded in a 1/4" section of steel I cut out of a piece of 4" angle. The soft bolts will come out and be replaced with G8 bolts in the future. I gave 'em a coat of POR15 and then a coat of ZeroRust. I dont think I will be worrying about rust again

Looks good...probably less flex being welded that way too. Did you get any pics of em after they were painted? Either way nice work!

Looks pretty good. If thats mig welding, your going too fast, and mabee a bit cold.

It is mig, flux core wire with no gas. I am a self taught novice welder, so any advice is appreciated
