Hey, sorry if this is a dumb question. I've had my 2004 5AT G35 Sedan for a few years now, but I haven't really been under there since 2 weekends ago when I changed out my hub assemblies (side note: a slide hammer is KEY for that project).

Anyway, while under my car I noticed that this was leaking on the driver's side of the car. What is it? LCA? Compression rod? Pictures are below:

 

It's your lower ball joint, I have the same problem. I'm guessing your car slightly pulls to that direction too. It's a pretty straight forward replacement but does require a shop or hydraulic press from Autozone slightly modified to install a new ball joint. Use the search tool above to troubleshoot it, there's 2 or 3 really good posts regarding the matter and replacement procedure. I haven't tackled this myself yet so I can't give you any real first-hand tips but I know it's been said and done here like everything else! Goodluck

 

Thanks!

I just did and found some really good DIYs. I also just ordered the Duralast lower ball joints with a 20% discount + ES dust boots. Overall it came to ~ $125, which is way better than what I saw dealerships were charging for parts + labor.

I'll attempt fixing my issue next weekend. Hopefully that will solve all the suspensions issues I've been having. If not, I'll look into replacing the compression rod bushings next. Thanks guys!
