Help with upper ball joint I'm trying to finish up my shock install but am having a problem with the castle nut for the upper ball joint. I see the nut has no threads in it and it doesn't get tight, just kind of spins on ball joint stud. I thought it was supposed to be torqued to 39 ft/lbs?
I'm not sure if I should just put the cotter pin in as is, replace the ball joint or get a new castle nut?

I assumed the nut should have threads, but I even ran to Autozone and took a look at a new ball joint and the castle nut it came with was the same way as mine???
I don't understand how it would not have threads, maybe they are just very fine and I missed it. I know its a M10 castle nut, but does anyone happen to know the thread pitch? I called the dealer and they said it was a 10 x 1 nut, so I'm assuming the pitch is 1.

yea if you took it off it should thread back in.....see if you can gently vice grip the bottom of the bolt and then tighten the nut.
Be sure you are pulling the upper arm down enough to get thru the knuckle. It should allow for some room to place the vice at the very tip of the ball joint bolt.
Post up a pic and we'll help ya!

Does anyone know where to get a new castle nut in this size, I cannot find this thing, nor do I know the thread pitch. The dealer can order me a bag of 5 but it won't be in for a few days, or a new nut comes with a new ball joint, but I don't want that. I'm running out of ideas for this thing.

Talked to the dealer again and found out this nut is part number 11506055. They also verified it's a M10 x 1...which seems to be an impossible size to find locally. I'll probably just order the bag of 5 from the dealer and wait 3 days to get it 
In case anyone is ever searching for this, here is a parts breakdown I found.
010 11506055 NUT,FRT UPR CONT ARM(M10X1X10)(HEX SLOTTED)(8.917)

So I ordered these from the dealer and they screwed me. Went to pick them up and they claim they didn't have my order. So after some waiting they went and brought back 2 castle nuts from somewhere. I go to install them and they don't fit...wrong thread pitch, it appears they gave me something with a 1.5 instead of 1. Anyway, I'm pissed so I got 2 grade 8 hex nuts and installed those with a cotter pin underneath, actually fit perfect. Should I be worried about this?

I work at a full service shop, and have buckets full of random stuff like that.
I recommend you go find a shop that does front end work/alignments and see if they can dig one up for you.
Are the threads on the ball joint still ok?

Yes the threads on the ball joint were ok, as I didn't force the nut they gave me enough to cause damage. The car is back together using a hex nut instead of a castle nut. I still used a cotter pin and it was a tight fit to get it in, so I don't see how the nut would back off. I'll probably eventually swap it out for the correct one, I just want to make sure I'm ok for the time being.

The only real difference is how shear forces are acting on the cotter pin in one nut versus the other. It's not worth going into detail about that here but it is worth changing out the nut to the correct one.
Good Luck.
and, a Dealer who screws you over? Who ever heard of such a thing?

I live in Schaumburg and work in Downers Grove, but am also up in Wheeling almost every weekend. If you had some that would be great and I'd come pick them up.
