Have you contacted Z1 yet? Do you have the street or track version and how long have you had them? Sorry for the all the questions but I was just about to order these.

Just happened in the last 2 hours. I have Emailed Z1 and had car towed to shop.
This seems to be an issue Z1 Front Upper Control Arm (race) followup - Page 3 - MyG37.
Had them installed less then 300 miles ago and these are the street version.

Keep us posted!!!

I'm installing these today the (street) version. Was yours assembled with the 271 red loctite?

I have no idea what Loctite they assembled them with.
I sent an Email to them last night right after it happened.
Received this Email today.

So there is a problem, but notified after the falure!

I received that email too I called and spoke with John but it was in regards to another item I purchased.

I talked to Chuck from Z1 this morning he said to have my shop contact him and they will sent new part. My shop isn't open yet, In AZ it's only 6:50am here.

He was saying that they have had some issues with these but thought most problems were from people or shops disessembeling the ball joint and not using locktite properly when putting back together.
Since I installed mine and was present when my car was alligned it was not the case.
None of us disessembeled the ball joint EVER. They were preessembled from the factory and were left that way.

Got the same email. Recently started hearing clunking noise coming from left front after greasing them to eliminate squeaking noises. Glad I didn't do the canyon run I had planned to this weekend.

There seems to be a patern formimg with these.
Zl is saying the ball jonts need a different locktite so the bolt doesnt back out.

Helm joint Malfunction
 

This is ridiculous,

Last night coming home from Palm springs my Driver Side z1 upper control arms malfunctioned as well. I received the same email that you have from spencer.

Luckily I didnt get into an accident. I replied to their email to verify that the upper control arm was the issue but not have heard anything back form them.

Terrible

Same side as mine same issue. CALL them they need to fix this issue before someone DIES!

I just called them and the guy (not Chuck or Spencer, didn't get his name) said there's no problem with any of their FUCA purchased within the last few weeks. I told him about the email people are receiving and he says it was a mistake and never should've been sent.

Something seems very fishy.

Ive only had my upper control arms since February 2016. This is still an issue. When the tow truck driver put my car on a jack he pulled out the bolt. showed me what the issue was. Im not sure giving me a replacement part will make me feel better about using their control arms.

Mods, you should make this a sticky post.

Is that bolt backing out, or breaking?

Just heard from my shop it backed out not broken. They have it back together to get in in the shop. Just got done talking with Chuck from Z1 he told me that they have revised the locktite they are using and the torgue spec.
I will have my shop do both sides with the newly suggested locktight and torque spec.

New locktite they suggets is 271 new torque spec is 57ft lbs.

For the time being I am going to remove my z1 fuca and replace with oem as my passenger side is making a **** ton of noise as of today and hearing the ball joint backing out is worrying. Noise has been there but only so slightly after my last track day.

hopefuly Z1 can help me defer some of the cost from the tow to the shop and the shop cost having to take care of the issue.

Well, you've got someone over there telling people nothing is wrong with these FUCA.Some guy told me the ones I purchased a month or so ago are fine, obviously, this is incorrect.

I sure hope Z1 going to help pay to un-install, un-assemble then, re-assemble and reinstall these fuca's

Here is the Email i received from Z1.

Here is a video that a forum member from myG37.com has put up on youtube about the problem these ball joints/heim joints are having.

Did he say anything about helping pay the cost of these repairs?

I emailed Spencer asking about this. I'm waiting for a reply.

All I got from Chuck on the phone call was that he would look in to it.
I highly dout they will step up and help us defer the costs of repairing the obviously defective parts. But hope they do the right thing!
I have towing and shop time here, just luck I wasn't hurt or more damage to my Car.

Here's an email I just got from Spencer @ Z1...This was in reply to my asking when the replacement parts were coming & if they plan to reimburse customers for the additional labor costs of having the repairs done.

since I've not had to be towed ((fingers crossed) I didn't ask about that.

Carey,

I believe they were having these kits completed and set to ship today, they should start moving either today or tomorrow from our local facility. Hopefully they will be to you within a couple days from that point.

The kit will include everything for your shop to do the repairs as outlined in the attached instructional TSB I just received. No change to the alignment be necessary and the install really should not take longer than a half hour or so, but yes it is my intent to follow up with you to get square.

Regards,
Spencer

Going to pick up car, shop said that they have never seen this before. Untreaded its self, threads are not stripped, no parts broken. charging me 28.99 for the threadlocker alone! I hope Z1 plans on reembursing me as I havent gotten the bills for towing or labor yet.
This is NOT RIGHT!!!!
When I was having noise coming from front end they said to check the lubrication and torque setting for the bushings NEVER said anything about the heim joint.

I was about to place an order for the FUCA glad I found this thread before i made my purchase. Maybe a recall should be placed for their FUCA if this is happening

Just picked up my Z from the shop everything seems tight and quiet, but then it did the first time they were installed.
The thread locker Z1 calls for cost me $28.99 alone, shop had to order it special and of course one hour labor for both sides. Without counting towing its getting expensive using Z1's FUCA.
So much for them being a bargain!

This has happen to me twice thankfully going a very low speed, I'm pissed i feel their solutions are not adequate. Im having to go back and put time and money and have my car out of commission for a few days to fix their problem.

spence4r @ z1 sends out an email saying it will be replaced, then someone else @z1 says the email should never have been sent out. then jon says replacement parts are being sent out. what is going on? sorry to hear the people who suffered are out of labor time & money spent installing these, tow charges, reinstall, alignment etc etc.
better to go spl and cut your losses.

This is a very unfortunate problem. I have been contemplating purchasing these FUCA's. I will be patient and follow this thread to see if their "fix" has been effective at eliminating this problem. I predict that the higher torque value with the higher grade Loctite will prevent the heim joint bolt from backing out. Hopefully Z1 will compensate you guys who have suffered from their product failure.

So the 271 Red Loctite is specifically designed for bolts 1/2" diameter or less which the bolt size that keeps backing out is. The 262 is designed for bolts over 1/2" which makes sense as to why it could be backing out. I mean if you put the 262 stuff in your jamnuts and haven't had issues with those loosening then you know it's a Loctite issue. I didn't get around to installing mine yesterday but plan on it today. My ball joint isn't pre-assembled like some of you from factory. So I got some 271 for 8 bucks for Ace. We'll see how she goes. First autocross this Sunday.

I went to the Locktite website and they say that the 262 is a High/Medium strength threadlocker and also give a breakaway torque value. With the 271, they say that it is for fasteners up to 1" diameter and that it is a permanent threadlocker. The only way to break the torque on it after it is cured, is by heating it up to 500 degrees.

Im considering going back to OEM Upper Control Arms. My tow alone cost me $500. I am hoping that they at least give me some type of compensation for this. If not I will have to at the least report them to BBB.

I see thank you.

Just received an email with tracking. Pleased to see that they shipped today and mine will be at my door tomorrow. Crapy situation but I'm glad its being resolved quickly. To those who experienced a failure I hope you get reimbursed in some form. Hopefully get new joints installed this week and will still continue to check them every 100 or so miles like the previous ones.

I have received an Email from Spencer Hutchins with Z1, letting me know they are sorry for what happened with their Control arms. He asked for the bill for my shop costs and any towing expenses and will make it right.
This is a great sign that they take responsibility, and want to take care of us in the Z community.

I got the same.

Very cool. And so they will continue to have my business.
