And if you DON'T have the right size wrenches, you should buy some. If you're even the slightest bit mechanically incline you can do this. Basics of what you'd likely need:

• Decent socket set
• Decent ½” drive torque wrench (https://low.es/2xdHDSR )
• Large crescent wrench (2’ - https://bit.ly/3aJN0XH )
• 2’ breaker bar (https://bit.ly/3cREM11 )
• Pickle fork (probably necessary to remove DL from the pitman arm - https://bit.ly/2W1vBEB )

This stuff isn't expensive. Most 14" crescents aren't going open enough for jam nuts on these components and don't offer the leverage the 2' one does. 2' breaker bar and 1/2" drive torque wrench should be standard equipment for any JK owner.
