I have 128,000 miles on my '01. 5 and one of the tie rod ends (I have not located the correct one yet) has started to sweak whenever you turn the wheel. I am sure it is a tie rod end because when I started and sprayed them up the sweaking quit. Thing is it did not start to stop sweaking all at once it did is slowly after I had sprayed them all trying to make it stop. 
Can you buy greasable tie rod ends to replace the ones that are on there? I have no death wobble even when you get to triples (Vol. Fireman... . don't ask you don't want to know). Steering still tight and in good shape. Any suggestions?
