How loose should the ball joint end be? Mine is moveable, but I can't find any looseness in it. Just trying to avoid the cost, if at all possible.

Thanks
 
Define loose!

Does the ball move up and down in the socket.

Does the tapered shaft not fit the tapered hole on the center link?

I would think that as long as it doesn't "wobble" in the cup it should be ok.

Mine had a noticeable click in it when I moved it from side to side, so I replaced it even though it didn't wobble.

The ball does not move up and down in the socket, but it does have a sort of a click when moving side to side.
 
Did you clean it internally?

It probably will not fall apart, but you might feel the looseness in the steering wheel.

You could get a new one and compare the feel. If it's the same return the new one.
 
I forget who @72bluNblu , recommended for my Lca pins and bushings.... maybe they make a quality PA?

Proforged.

They do make a pitman arm for the large sector power steering box, doesn't look like they make a small sector one for the earlier cars though.

If the ball joint doesn't have any end play it should be ok, although clicking isn't really a good sign.

Yeah, I don't want to go to the trouble of reassembling this, only to have to remove it again for replacement.

P.S. This is for a manual steering box.

Totally understand that.

Manual box with the stock '70 center link?
 
That would be up, sir.

Ok. So yeah, that's a '67-72 centerlink. The '73+ pitman has a ball joint that points down. '67+ all the centerlinks were the same, V8 or /6, and in '73 they swapped the taper direction and took the 90° turn out of the centerlink where the inner tie rod end goes.

Unfortunately, it doesn't look like Proforged makes one for that particular application. I have used Mevotech stuff before too, haven't been burned yet but the Proforged stuff seems better.

How much do you drive the car?

1000 miles a year?

Depending on how old you are a parts store replacement will last you a life time.

It's an easy part to replace so I would not get too hung up on it

Yeah the only issue is some of the new stuff doesn't have the right tolerances. I've run across ball joints that were so tight they would effect the steering effort and some that were sloppy loose right out of the box. If the replacement is made correctly you're absolutely right, but the quality control is more hit and miss with some of the replacements.

Well, I haven't driven it in years. It's been stored in the garage, torn apart, for several years now. I'm ashamed of myself for that, and am now trying to get it back together so I can once again enjoy it. I agree it's an easy to install part, I just don't want a part that may fail during a drive.
