Lower ball joint nut? Supposed to turn with the knuckle?

[my2monkeys]

Sometime ago I replaced my ball joints. Now as i trace down a wonky steering I am seeing the bottom ball joint nut turning when I turn the steering wheel.

Is this correct or is the joint bad and the big bottom nut should stay straight ahead as knuckle turns left and right.

ball joint nuts shoiuldn't be moving at all. That's a loose ball joint.

That link is a bit long.

Take a look at the one joint that is cut away, you will notice the taper on the ball joint fit inside the taper of the steering knuckle then tightened tight enough so as to move as one (both the ball joint shaft and knuckle) them the nut is pined using a split pin through both nut and ball joint shaft locking both together.

The answer is yes, the nut should turn with the knuckle if the nut is torqued to specs.

It should turn with the knuckle. The tapered shaft of the ball joint mates to the knuckle.

The end of the stud, the nut, and the knuckle it is bolted to should all stay together. If it is not it implies the taper stud is turning in the knuckle. You should try torquing the nut, if that does not fix it, expect to need to replace the balljoint and/or clean out the taper in the knuckle, maybe re-ream it gently or even have to replace it if it is too badly damaged for the taper stud to stay put when the nut is correctly torqued. I would start by simply disassembling it all, brakleen/wirebrush/rag clean the hole in the knuckle and the stud, check for any damaged areas of the knuckle hole and then reassemble, if that doesn't help enough you need to consider if it's worth re-reaming it or just toss a better condition junkyard knuckle at it for like 10 or 20 bucks.
