Hey guys need help here. That part leaking is the steering knuckle correct? Or is it the lower control arm bushing? Gonna have to replace it. Right side of a g35 coupe. Anyone know how much it cost just to replace the bushing? Lmk thanks

 

That's your steering knuckle ball joint. You can't buy it separately from the dealer, but you can buy one from eBay. I bought one from RockAuto for about 50 bucks I think. I then rented the ball joint press from Advance Auto and swapped it out. It's not too hard, but does require a lot of elbow grease.
