4600 tie rod ends

[wpc45]

My tie rod ends are loose on my 4600. Both shafts: from
steering box to axle and from wheel to wheel. Can new ends be
welded in place or must I replace entire shaft? If new ends can
be welded on, what part numbers do I need?

Here's a source except that they call them drag link ends.
