Boot replaceable?
 

All,

While mucking around the engine compartment cleaning it I looked down and noticed a grease boot had ruptured at a link. Is it possible to replace the boot alone or do I have to replace the whole link? Is that an inner tie rod (that would need to be replaced?) It is on the drivers side of a 2000 F250 SD CC 7.3 4x2. I think the link on the right of the top picture is called a Pitman arm?

Thanks in advance,
