Remove the lug bolts and pull the tire off.

You can now see the tie rod end. It has a jam nut at the back to keep it in place.

Loosen the jam nut. It is much easier to do this before removing the tie rod end from the knuckle.

A spritz of penetrating oil may help if it is seized.

Only loosen the nut. Leave it in the same position. This will act as a marker when you install the new part, keeping the wheel alignment similar.
