Not so easy.
This is pressed into the lower control arm.
So :
Honda knows they have a problem with the passenger side lower ball joint on 2001-2005 Honda civic. refer to Honda service bulletin 04-079 dated December 21,2004. the bulletin describes how to remove the ball joint and Honda now has a ball joint replacement. however, the service bulletin suggests checking the opening in the knuckle to make sure it will receive the new ball joint. the bulletin also suggest that Honda will repair it even if it is out of warranty as a good will gesture. if not, purchase the entire knuckle assembly with a ball joint from majestic Honda. it will cost you about 100 dollars .
The 2001 Honda Accord lower ball joint torque specification is 90 pounds. The lower ball joint should be torqued in 45 pound intervals.
Look at lower rear of engine
upper or lower?

You'll need a socket big enough to fit on the CV nut and you might need a fork for the lower ball joint. Both can probably be rented for an autoparts store that has tool rental program. It's free if you buy the part there.
You have to replace the lower control did assembly .

I recently removed the lower ball joint from a 91 Civic, hopefully it is the same as yours. You need a fairly large double jaw gear puller. Loosen the castle nut, but do not remove it. Place the jaws of the gear puller under the boot of the ball joint (be careful not to damage the boot). Then place the screw part of the puller on the end of the ball joint bolt and tighten the puller as tight as you possible can. Then use a blunt punch and hammer to hit on the lower arm where the bolt goes through it, it requires quite a vibration to jar the ball joint loose. Good luck.
