Loose nut on tie rod!

After running across the thread that discusses the loose nuts on the control arm ball joints, I decided to inspect mine. The good news is that the control arm lock nuts appear to be fine.. the bad news is that the nut on the passenger side tie rod was completely loose! This makes me wonder what else could be loose. When I checked the driver's side, I noticed that the green safety paint is not visible on the nut where it should be.

I happen to already have a SC appointment this coming Monday to look into a clunking noise that's coming from the front end somewhere, which can be heard when below 10mph on a bumpy road. It sounds like something else is loose on the front end, besides the nut on the tie rod. At higher speeds, I can't notice it. After finding this loose nut, I've requested a thorough inspection of the entire front suspension/steering assembly.

Anyway, I just wanted to share this with the forum since I find this somewhat concerning as a new Tesla owner. I've already shared the pictures with my SA and am confident that they will address this appropriately.

They usually loosen that nut to perform an alignment, then they need to re-tighten it. Definitely a good catch, because there is a chance it could work its way loose. A friend of mine had a brand new Cadillac CTS-V (very fast, with Vette engine) where this happened at high-speed. Luckily no one was hurt as he was alone on the highway in a wide open area, but it was crazy scary.
 
I agree, that’s what I was thinking too. I wonder if it has now vibrated itself out of alignment after putting 500 miles on it over the last 3 weeks.

The car was delivered fresh from the factory with a 59xxx VIN and there was zero miles on the odometer. I believe this was how it was left from the factory.

That's just the adjustment nut your tie rod isn't going to come off from that. If your tie rod did somehow back out enough turns to come off you would notice it happening long before it did. Your wheels would be pointing out like a V and the car would be pulling hard.

I would just tighten it and drive to the service center. Tell them you want an alignment because it might have moved slightly.

Agreed, and that’s exactly what I have done. However, the front end suspension noise still exists. I recorded it on my drive home today and have shared it with the SC via text. I’ll see what they say in the morning.

I wonder if the green marks are actually part of a poka yoke quality process?

I've seen stuff like Tohnichi Mfg. Co., Ltd. | Products | Tightening Assurance System | Tightening assurance system (Pokayoke) at Tokyo Motor Show.

https://www.pcsllctn.com/promotion/ has a brief video. Basically, if you tighten something to a specified torque, the wrench automatically makes a mark on the nut to indicate it has been tightened and to the correct torque. Tohnichi Mfg. Co., Ltd. | Products | MNTD is an equivalent for screws.

Thanks for your posts. Please make sure to post a follow-up.

That's the jam nut for toe-in adjustment during alignment. Torque doesn't matter here--just make sure it's tight/snug.

Make sure they check your alignment and tires for wear as that shouldn't get loose.

The tie rod is steel so the threads are probably fine, but note it with your service advisor.

Interested to hear what the SC does for the under 10mph clunking sound. I have noticed that sound on mine as well. Haven't made an appointment yet tho.

Please keep us posted.
I’ve noticed a thunk sound too so am interested in what they say. I get the sound also when driving slow and drive over a small hole (top layer of pavement is gone) or a bump that causes the front wheel to drop. It doesn’t occur when I hit bumps.

I too got the (likely same clunk), 1-2 clunk from front under side noted when lurching forward (pressing accelerator pedal) 1-20 mph.
Today, my local SC checked it out, acknowledged that the clunk is there but says that it is nothing to worry about because it's "normal" sound. Somehow I do not fully believe that its normal, just hope it's not doing damage.

OP, keep us posted. Thanks for sharing.
I am going to check on those nuts now. :eek:
 
So I dropped off the car on Monday at 930am and went through the telephone drop off process. After discussing the items I had on the service ticket, they decided to have a tech join me for a test drive to try and reproduce the issue. We drove through their parking lot and managed to find some rough somewhat bumpy areas and was able to hear a very good sample of the noise. Also, I mentioned to him that it was easy to reproduce a similar clunk sound just by turning the wheel back and forth, two to ten o’clock, when you’re parked. When I shared the photo of the loose nut, he was shocked and he agreed that a thorough inspection of the front suspension/steering assemblies was in order.

I picked up the car today and am happy to report that the noise is gone!! Unfortunately, the ticket does not go into any detail about what was found.. only that they checked the torque on all front suspension components and verified that they are all torqued to spec.

Thanks, for the update!

Quick question: do you hear a clunk sound from the front wheels when you drive over certain bumps? Specifically, bumps that cause the wheel to drop quickly?
 
Thanks for the update.

It would have been good if they provided some additional info. Only 2-3 days at the SC so any fix probably wasn't drastic.

Had same issue on my brand new 22 MYLR - day I got it I heard the noise thought it was frunk noise. Went to get my state inspection today with 1000 miles and he noticed it I didn't tell him and it was loose nut on tie rod drivers side. It definitely feels tighter now on steering wheel but my concern is there any damage now to tie rod or control arm as whenever I went over a bump I could hear the noise which I now know was the nut jiggling.
