How to remove ball joint

I have a 2004 polaris sportsman 700 and i am wondering how to remove the ball joint. I have the cover off that holds it, but i need a good way of pulling it out. Any help would be greatly appreciated.

Polaris makes a tool for pulling ball joints part # 2870871. Or you can make your own.
here is how i made mine..

I found a thick bracket laying around in my nuts and bolts cart and cut it 1 1/2" it already had a hole in the center of it that would fit over the ball joint, I also used a thick washer and a larger nut for a spacer as the ball joint comes out you will need a spacer to continue to pull the ball joint out.

This is what it looks like mounted

I used needle nose vise grips to keep the ball joint from spinning until it had enough pressure to start pulling the ball joint out.

This is how it should look as the ball joint starts coming out.

Note, the nut size is the same nut that is used as the lug nuts on your wheels... the castel nut i was useing stripped out the the threads, so I used one of the lug nuts to finish pulling it out.

Install of the new ball joint is just as easy. I used a 7/8 deep socket and gently tapped the new ball joint into place.

Use some blue lock tight on the srews.

and there you have it!

Hope this helps someone needing to do this job.

just my 2 cents. i've had alot of luck with simply using a propane torch. heat just the aluminum around the ball joint itself and after a few minutes you can slide it out with pliers. also put the new balljoint in the freezer before you begin taking anything apart (don't let the wife see) and when it's good and hot the old one will slide right out and the new one will slip right in. changed probably 200 or so like this and usually don't even have to pull the rotor off, did it with the wheel off and the a-arm dropped out of the way. 30 minutes for both sides start to finish. and make sure and put on a new boot!

Thanks guys for the write ups. I almost bought the Polaris tool when I thought I had broken a ball joint. Ended up being a bent A arm instead but I was dreading trying to pull it out. I can easily make one of those tools and with adding some heat they should come right out and the frozen one go right back in. Thanks again.

I just use heat, then put vice grips on the ball joint shaft and hit it with a hammer,if you have a big enough deep socket to fit over the shaft and on the collar of the new joint, get everything ready and install new one while strut is still hot, it will tap right inn with deep-socket and hammer

Just did this as well. Had to use heat and just cut a piece of thick pvc pipe and used several washers as spacers to pull them out. but if they are worn enough, you may end up pulling the ball/ bolt out of the socket. This happened to me. I had to weld the ball back in the socket and then no problems. if you have the capability to easily, i would weld them in fro the beginning.
