Nubs on stabilizer rod worn down. Can these be replaced?

If you have enough thread there, screw on 2 nuts, then jam them together. Work same as welding, but if you need to take it apart you can

You need to use a deep well socket if you go this route. Otherwise, it may just grab the first nut and break it free.

But unlikely you will ever need to take it apart, so a quick tack weld should work fine.
