R107 Upper Control Arm / Upper Ball Joint
 

The top ball joint has some movement. A bad thing.

My research suggest that the top ball joint is repaired by replacing the upper control arm. Wow, that seems like a big project.

Questions please:

• Is the upper ball joint repairable?
• Is it true that the whole control arm needs changed?
• I usually replace suspension parts in pairs, but the control arm?

I see that Pelican Parts has the lower ball joints and the control arm (with no upper ball joints available). All consistent with what I've read, replace the control arm not the upper ball joint.

Summary:
What are my options?

Thanks

Just replace the whole thing, it does not cost much and is fairly easy to replace.
