Grease your new ball joints if they require before installing them

Vehicle: Dodge Caliber 2009 sxt

I bought a pair of control arms for both sides, and installed them 3 months ago, then nowadays they started to make noise, because im dumb: I didn’t grease the ball joints before installing them

And now need to buy new ones and replace them again 🤦

I learned later that Those ball joints come as sealed and manually greased, mine was 2nd, I didn’t have clue to grease them
