Thanks for the replies folks.
The magnetic test revealed the ends were steel. I can only guess that since this 99 was a very late 99 they may have started using upgraded tie rod ends. Or this was a second set of tie rod ends and they only lasted a short time, car has only 71k on it.
Basically it appears the failure wasn't really due to the joint, but rather the boot tore on both sides and left the joint wide open for dirt.
I was only able to find one site with instructions on replacement.

Never having replaced tie rod ends on a VW, I was able to do it myself in about an hour. I lost an hour of time having to truck to the home depot to buy a blow torch to get one end loose. Other than that it was pretty un-eventful. Going to take it in for an alignment. I tried using an adjustable square to measure the length of each end before un doing it, but I would imagine its probably close, but off. Another mystery is the tightining torques, I don't have a manual yet so I just torqued it down to where it felt like it should be.
