Toyota already ruled this as no big deal and wnl. Nobody is getting anything changed by a dealer with Toyota’s blessing.

And after my talk I just had yet again with Toyota headquarters we are all screwed on anything replaced related to the suspension. I asked if they can replace the sway bar bushing as that makes the same issue an they said no due tot he tech bulletin. I said will they ever replace anything related to the suspension and they said no. I said so their is no warranty for them them? And my reply was we will keep telling you the same thing and was inform I was only called for customer service reasons. When I pointed out that means fixing an issue and following threw with warranty they hung up on me. I was also instructed that any fixes for the suspension I needed would have to be done by myself.
So yes Toyota has completely given up on customer service

Was not very cold this weekend here in NY but here is a quick clip of the noise. Noise gets worse the colder it is outside.

That’s not even close to the noise we are talking about. It’s a hollow thunk like a blown out bushing or strut. Also you can feel a knock on the floorboard when it does it in very cold temps.
That sounds rubbing on the shock to me

It makes the clunk noise as well however it was almost 50 degrees on Sunday so the clunk didn’t appear as much. That said it shouldn’t even make the noise it’s making in the video.

I agree a new truck shouldn’t be making that just was saying it’s not the same as we are talking about. Also, I’ve not seen it on the rear but saw some other threads talk about the rear.
I’ve emailed FOx service asking it they can fix or service and tune mine if I pull them and send them in to see if that could be a way to fix this issue

That just sounds like the seal in the shock is dry and squeaking.. Id have to double check what to put on the shaft, but a simple lube should fix that.

It has been around -13F all weekend and the clunk is definitely louder as it gets colder. Even to the point where my Wife noticed the noise riding in the passenger seat.
Pretty dissapointing that TRD/Fox cant figure this out...

Mine in SD was so bad the passenger floor board felt like a hammer hit it and everyone in the truck can hear it. I can feel it travel to the driver floorboard. But to them that’s normal 🤣🤣🤣🤣🤣

They have no intention of fixing it. The reply I got back from Fox was this is a normal issue with thousands of shocks that no one can explain. Again with the it doesn’t effect performance or longevity. Work with your dealer.
So basically don’t buy a pro. Buy another and get a different shock that’s not fox. This isn’t my first 4runner or Toyota I’ve had, but it will be my last after seeing how they handled this. And Fox will never get any more of my money

Are Fox shocks bypass shocks? I'm not so familar with trucks or SUVs, but bypass shocks in the tuner/scca racer communities all click and make noises. My Ohlins DFV shocks (which are bypass shocks) on my Honda S2000 click and clunk when it is cold outside. You can hear it a lot when you first drive it in them morning and it's chilly outside (like below 50ish). Once the shocks warm up (by driving around and the shocks soaking up the spring's forces), the clicks/clunks go away.

I've also had the privilege of being invited to drive a friend's scca rallycross car. I asked him... "hey do these things use bypass shocks (not knowing anything about rally), and he said yes and asked why... so I told him my Ohlins makes the same sounds as his rallycross car.

So perhaps what Toyota is saying is actually normal.

Say it slower and louder for the people in the back.

Well thank you for trying to be helpful unlike more people that keep saying it’s normal and deal with it. This isn’t a click. This is a loud hollow thunk almost the same as when your bushing go bad. Yes some shocks make a click, but this isn’t that. Also, it’s only one shock. If this was a standard working action, wouldn’t it be every shock instead of one? In any case, when you feel your floorboard hit from a shock, something isn’t right.
I’m still a believer that it’s possible not the shock but because of the tech tip they will not try to fix anything else. Hence it will not get fixed and we have no warranty for that part of the truck

Why don’t you crawl under and figure it out. You seem to know so much that it should be easy for you to figure out. After all, a 70k pro shouldn’t be making these noises!!

They are internal bypass shocks, yes.

Stick a GoPro under there and play process of elimination.
