The original issue was the CV axle. We had replaced the CV axle, but when we tried to screw the nuts back onto the ball joints the ball joints started spinning regardless of the amount of pressure applied. Also, when we tried to completely remove lower ball joint, it would not move no matter what we did, and in fact when we resorted to impact hammer it blew the insides of the ball joint out of its cylinder and it's stuck in the lower control arm. This is why I need to replace it because it's a driveway job. I know it might be a hassle, but could someone please tell me exactly which parts I should buy to finish this job and get this suspension good again? So far the problems have been the control arms and ball joints, but every single kit I find online seems to come with a tonne of parts that do not necessarily look the way mine do. Thank you so much for the help.
Control arm ball joint upper is stripped and will not spin. Do I replace the control arm AND balljoint?
Suspension. Do I need to replace this? Or -should- I replace it?
Lower control arm needs replacing.
This is why I need to change out some of the suspension.

 

go to the junkyard and pick up another knuckle assembly that is better shape than yours. No sense it fighting against a rusted part when a replacement is much easier...and less headache.

 

So THAT is what it's called? The part that is connected to my rotor? Knuckle assembly?

 

YES.

 

dont buy knuckle, just take what you got to the shop and have that garbage pressed out and new ball joint pressed in. new balljoints cost $30 each on rock auto and lower control arms are $42. being an old car you prob need them changed anyway. prob should change uppers too since your lowers are bad. change the tierods too their cheap.

 

i changed upper/lower arms and balljoints, sway bar links/rubbers tierod inners and outters and boots, even changed shock only cost like $300 for everything

 

nice having all new parts you will notice the difference
