Good morning,
I attached the procedure below with some pictures for you. You will need a portable press for the removal and installation of the ball joint.

Tools Required

Hi my lower ball joint is bolted in. My truck has a 6 inch pro comp lift on it and my ball joint looks to be real easy to replace. What I am having a problem with is getting it off the knuckle because the knuckle has too g o downward to separate from the joint. So do I need to loosen my torsion bar and take the hub off or can I just pop the upper ball joint and then the lower one and move the knuckle out of the way and unbolt the ball joint then put the new one in and just put it back together or is there something I need to know first like torsion bar or the the drive axle do I need to go through all that or just unbolt and rebolt it looks easy I just like to know what I am doing before I do it that is and I do appreciate your help thank you.

Okay, you never mentioned it was a 4X4.
Yes, the torsion bar has to be backed off to release the pressure to allow the arm to move down.
The other way is to release the upper ball joint and lift up the upper control arm to free the lower to move.

Hi, I was wondering about the torsion bars. How do I take the tension off them? Do I just need to loosen the bolt on the cross member? I have never had to mess with them before. Thank you again.

I attached a picture for you.
Yes, you loosen the bolt all the way back to release the tension.

Thank you. Oh do I need that tool or just count the threads and match it back up with what it was when I started? I know enough to not remove the adjusting bolt just mark it and align it back up, right. Well I appreciate everything Thank you.

I would count the number of turns you back off so you can tighten it back up to the original position.
