has broken the ball joint on the passenger side?

Hello,

On this vehicle the rear control arm comes as an assembly that includes the ball joint.
To replace the control arm you will have to lift the vehicle and secure it on jack stands.
You will need basic hand tools and a pry bar to get this part out.

I have attached the replacement procedure for your reference.

Please let me know of any questions.
Thank you.
