If you feel comfortable wrenching on cars, then it's not difficult - at least in principle. The job can easily turn into a headache if the jam-nut doesn't budge, or if the joint won't separate from the mounting hole in the knuckle. PB Blaster can be your friend to loosen the fasteners.

If you can accomplish freeing the tie rod, then the only critical part of the job is to count the number of turns it takes to remove the tie rod from the threaded end so you can turn the new one in the same number of turns.
