Lonnie, the 3203 doesn't have ball joints.
New tie rods.

The only thing I can see is getting thicker rod and bigger heim joints to beef up the steering on these. (maybe use 3/8" or 7/16"all thread???)
On the spindles, I welded another gusset on the top (just like the bottom) to beef those up. I hit a large rock and bent mine, so i bent it back and welded the additional gusset.
