All that info is why I didn’t think they should be turned with the wheels in 2wd. I have a Lariat and yes I have already heard about the warm up hub connection and why it does that yada yada. This was today in 50 degree weather in a warmed up truck.(conversely the only time I don’t hear the cv joints clicking is first thing in the AM on my 4 mile drive to work). The video was not meant for you to hear the clicks. The clicks are much more audible inside the cab under my feet. I posted those videos in another thread. That will be confirmed tomorrow but it’s defitently cv related and a part that’s already been pulled off the truck and replaced when they pulled the first one off after and installed the new one and didn’t replaced the messed up seal.
But now I know why I can hear the screwed up cv even when I’m in 2wd. Because the hubs are locked in and turning them. God knows how many screwed up things there are now.

By a tech not knowing it’s a 30ftlb nut or possibly not having proper depth protrusion of the spindle when going to tighten on top of tightening it with to much force is how I imagine it happened. The IWE May have been damaged at that time also, but the cvs have been pulled out of at least the hub 2 times since then so inproper reinstallation could have damaged the IWE at any one of those junctures.

I do know about the warm up hub lock. But what’s funny is I don’t hear the cv clicks in the morning when it’s cold and at a time when the hubs might suppose to be locked when all other times of the day I hear the clicks and the hubs are locked when not suppose to be.
I have had all last weekend and this week to wait on my appointment tomorrow so I’ve been checking stuff out myself. I started wondering why I even heard a bad cv in 2wd in the first place. If hubs were working I probably wouldn’t have heard clicking until one day when I went in 4wd or 4A. So I haven’t put the go pro on it in the mornings to see what it’s doing yet since this has all been tested and realized with the hubs just today. But now I’m very curious why during a cold morning I’m not hearing the cv clicking and if they are not turning because my hubs are locked which would be contrary to the only time they might “suppose to be” turning during the warm up hub lock period. Maybe the trucks doing the opposite because of the issue of the iwe being messed up or it’s possible when everything is cold the bearings smacking noise in the cv aren’t moving around as much yet and sticking. Without knowing exactly what damage is done to the CV to cause the clicking its hard to know yet. But I’m almost fully expecting tomorrow morning to find out the hubs are not locked first thing in the morning, thus no damaged cv joint spin and no clicks heard.
But one thing is for sure in that the hubs are locked when the truck is well past any warm up but tomorrow I will be mounting the camera to see why the cv might be quiet during that 4 mile drive in to work when the hubs are quite possibly suppose to be locked anyway during that time.

I think that is an interesting thought. And I would honestly be happy if the clicking was not the replaced cv shaft and all the issues were localized at the actuators to the hubs. One less thing to fix and go wrong.
The one part of that theory I’m still trying to picture is where is more pressure coming from during that warm up? If the trucks sending signals to engage the hubs for a warm up protocol it would be cutting vacuum. If I put it in 4A I still hear it so I know clicking doesn’t stop when the hubs are suppose to be locked. Do you think that warm up protocol is so instantaneous when the truck cuts on that no vaccum drawl even ever touches the actuators from just turning on the truck in 2wd? I was thinking vacuum probably would start as normal and when you put it gear the warm up protocol would then take over. But if not and it’s instant I guess any peices your talking about would have had time to settle in the cold until the next morning.
Whats interesting is that originally when the clicks got real bad and non stop every drive for a couple days I decided I was going to park the truck and wait for the appointment and it set for 3 days. When I decided on last Sunday to go pick it up from the dealership parking lot and bring back home to check some stuff I read about, the noise was silent and I drove around for 15 miles trying to see if it was gonna come back. It was silent the following morning to work also. Then I jump in to go to lunch and bam it’s back to its clickly normal self. Maybe sitting long enough helps to keep any pecies together idk. That was the pattern with it, you would either hear it an entire drive or not hear it for an entire drive. But now even on the last two silent cold mornings I’ve eventually heard it began as I got fairly close to work.
Who knows I just hope it gets fixed and everything back together properly and that the tech understands what they were and why they happened so more issues spin up from installing parts and putting things back together properly.

Oh I didn’t know it was a time thing or I would have told y’all that I’m all about remote start and my cold morning drives probably all start with a at least a 5 minutes warm ups often longer. Especially lately as I get in the truck wondering what’s going to happen and thinking about stuff ect...
I’m curious what you at trying to see with shifts 2h to 4a and then 4h? I forgot to mention one night I was driving around frustrated with my brand new truck and the clicks under my feet, I did shift to 4a and 4h to see if noise stopped(it doesn’t) and after being a little aggressive with it testing in those drives because things just feel funny(now I know why), but still below speed requirements I switched it back to 2h as I was on a ramp for a coming 70mph hwy merge I went back to 2h with my foot off the gas and somewhere between that and then going to accelerate the passenger side went nuts for a short burst with the sound I hear people describe as the IWE spoke and card noise. It startled me enough where I don’t even remember exactly what I did beside slow down but it stopped quickly. I figured it was either related to the click on the driver side or me being to quick but that’s the only time I ever heard anything on that side. She was espeically clicky with me that night until we got home. Haven’t touched 4wd drive sense as I didn’t want to make anything worse if it was related to my click issue.
I can mount that Go Pro just about anywhere if you tell me what you might be wanting to Hoan in on. If you want to hear the clicks I can send you enough videos to drive you crazy. They are very easy to hear in my videos from the cab.

I planned on checking the other side in the morning but at this point I don’t even want to have to wrap my head around the potential problems of that side not being locked while the driver side is. I may just tell them to make sure they test that side also tomorrow. Last night when I got home I kept the truck running in 2wd and grabbed the half shaft sitting next to driver side CAT and turned it and both driver and passenger side cvs responded and turned with me. That actually initially put my wonders about checking the IWEs for issues to rest for one night as I figured with both wheels on the ground that if one or both hubs were not functioning correctly and locked in 2wd that they or one would not be able to spin when I spun the whole shaft if locked into a wheel with a truck sitting on it. I also didn’t think I would be able to turn that drive either if one hub was giving me resistance. But they did spin.
