What do you mean seized? The pin should be pretty easy to remove, but give us more info on what's going on.
Once you have the pin and castle nut off, leave the BJ bolted to the upper Control Arm (the 4 bolts on top). Then place a jack about 1-2 inches below the LCA. Then use a BFH and bang on the spindle where it meets the BJ until it falls off. If that doesn't work, you could try a BJ puller or pickle fork.

I can't remove the pin..it's stuck solid in the bolt/nut...to such an extent that it bent the top of my long nose pliers!
What's LCA?? I assume BFA is a big f***in hammer??

Lower Control Arm. Sorry.
Correct on the hammer.
Can you tap the pin with a hammer to break the rust? Maybe grab a box wrench and try turing the castle nut- maybe its pinching the pin. Heat?

You'll have to get in there and tweak that cotter pin out ... Like Ardent just said, maybe the nut is forced against it, so try turning it a little with a wrench. After this, I usually use a pickle fork to separate the BJ from the spindle. I leave the BJ castle nut on a few turns, so when the BJ shaft comes loose from the spindle, it doesn't all fly apart.

Second Yopar. Back that castle nut off but not all the way off. Also keeps you from ruining the threads on the balljoint should you have to put it back together if you can't get it loose. Hammer and pickle forked worked for me but that was on my old Nissan.
Good luck.

Nope, they are empty. They need to be done once installed! Good to hear you got the one side done. I just did the driverside the otherday when I installed the Ball-Joint spacers and had the same issue with the cotterpin, so I just took the sawzall to the castle nut flush with the top of the spindle and slced it off!

For grease, I use bearing pack grease, the typical goop you find in shop grease guns.
I may be stating the obvious, but make sure you dont over fill the boot

Where did you get the balljoints from? OEM are already packed with grease and I would hope aftermarket are too.
The obvious is to make sure you have the correct zerk fitting on the bj and the appropriate fitting on the grease gun. If grease leaks out then you probably just need to tighten the collar on the grease gun fitting and keep it straight as possible while pumping the handle. Ocassionally the spring loaded ball in the zerk fitting is stuck, so just push it in with a screwdriver to break it free.
I replaced all four balljoints a couple weeks ago and only one of them was a little tough to break free. I put 3/16" shims under the pickle fork, beat it a little harder and finally it came out. The castle nuts lined up correctly on only two of the studs, so I just safety wired the other two.

Here a valuable tip i picked up in a shop a long time ago about grease nipples.
take something pointy, and work the grease nipple ball, make sure it 'breaks' when pressure is applied to it.
Once youve done that, hold the grease gun fitting on it,and apply pressure. grease nipples can be a PITA.

Another tip to make it easier to replace the upper bj's is to jam a block of wood in between the upper control arm and the bumpstop before you jack it up. This gives you some extra room and makes it easier to maneuver the spindle back on the ball joint.
I use a 1x4 I have in the shop for that.
Also the last time I did it I had a lot of trouble using the pickle fork too. I was already in the job and didn't want to go to the store again so I ended up putting a pair of pliers under the fork and it gave me just enough extra bulk to break it loose. It ruined the pliers though...
All of the aftermarket ball joints I have seen are regreasable and come with no grease in them. They're half the price of oem though so they work in a pinch. After you grease them that is.
