Hey, I recently bought my first infinity a couple months ago. I was wondering, how many ball joints doesn't have on the front? And can I replace just the ball joints, or does an entire part have to be changed out? Ive attached four photos to help. I took two pictures of the left side and two pictures of the right side both on the front of the car.

 

Pictures 1-3 are your tie-rods. Just replace the ends. Dirt cheap. You might be able to get away from having to get an alignment if you paint the threads on the tie rods before you change the ends, then match the new one up to where the old one sat.

 

Are there two per side? I just need to know what to order. It seems like Oreillys and Advanced don't know the Infiniti very well. I always fork out the extra cash for the unlimited alignments, so I'm good there. I appreciate the feedback.

 

No, just one per side. The 4th pic was your lower ball joint. You might as well check your upper ball joint too while your at it. Need to take the tire off for that one.
