Just thought of this but did you replace the bolts on the power steering res.? Maybe the original bolts aren't clearing and are getting hit?

Ball joint broke
 

Well my drivers side ball joint JUST BROKE. I just put these on a few weeks ago very few miles. Not looking very good for Z1's upper control arms.
Thinking I should have spent the money on SPL's.

Oh hell no..? what happened?? pics??

looks like ball joint bolt backed out. seems like a pattern with them. They have revised them and if you check the install instructions on their web site the revision date was this month!

I think I bought mine from Z1 around the same time you did.
Some kid there today told me the email from Spencer was mistakenly sent out and there's no problem with their FUCA that were purchased recently.


Well, I just heard from a member who got theirs on 4/8 and Joel told him the factory used the wrong loctite on the ball joints

My driver side fuca is making some serious clunking noises. I'm afraid to drive the car after reading some of the posts in the other thread about these arms.

Something fishy going on here.

Just talked to my shop nothing broke the bolt that holds the heim joint together came undone. They have i back to gether and I am waiting for a call from Z1 about what locktight to use on BOTH sides so this hopefully doesn't happen again.

here is a video from a member of the G37 forum he did a video of these issues so people can see what the problem is.

I called them about the cap coming loose one day I guess I'll have to call back and see what the deal is. After 100 miles I checked everything out to make sure nothing was loose and noticed that top bolt was so I tightened it up after a call with z1. I haven't had any issues driving wise but I ordered the product back during black Friday I believe.

Boy am I glad when I installed the z1 arms I used the red lock tight on those 8mm Allen bolts..
