Looking for help identifying a clunk.

Sounds like you found the problem.

One other thing I do for suspension noises, is to crazy rock the truck by hand so it is just bouncing up and down. That is how I found my last broken swaybar link.

However, if you have nothing to hold onto while doing this ot can be tricky to get it moving.
In my case it is simple as I just grab the top of my center roof rack and start bouncing it up and down.

Had my wife do that last time while I am watching under the truck, and clickety clackety another swaybar link gone. That is 2 in the last 8 months. Truck gets beat on while off road. Not driven hard, just too many trips on shit washboard and pothole roads.

I just grab that red circled spot and start rocking it like a son of a B. If the noise is not reproduced, it at least provides good entertainment for the neighbours. Starts to look like its on a trampoline.

 

Mine does the same thing. I believe it is the castle nuts on the ball joints that needs to be tightened. They will feel tight but you have to really wrench them down. I had the same issue on my Jeep and it solved it immediately. I tested one of mine the other day to see if it was slightly loose but it wasn't and I didn't have quite the leverage I needed to really tighten it anymore so I left it alone.

 

Well it wasn't the steering rack guide, or if it is it's past the point of fixing by tightening. Still made the noise with the steering stiff to where it would still turn on bends in the road hands off the wheel. I backed it off to a comfortable level. I tried swapping the sway bar bushings as well, the drivers side one looked widened out. Still makes the noise, but for $20 I'm still glad I did it. Here's another quick clip.

seems to be triggered by body roll or flex, or cycling the front suspension. The swaybar endlinks feel tight? but I may try swapping them as well.

 

Ok, that sound. Mine has been making that sound for 5.5 years now, and over 25K off road miles now. Sound has not changed in that time.

Whatever it is, is still attached under the truck. When something falls out and clatters behind the truck then I guess I will know what it is. Until then, I chalk it up to “f’n rackety new fangled trucks”.

After a “brake service” at my dealer, my brakes are 10 times louder than that sound, they make a huge clang on about every third stop or so. So loud that folks walking down the street jump a foot high and duck for cover.

Going to take it to the spot that did my ECGS bushing and see of they can tighten it up. My brakes never made a single sound in the 3 years prior to that “brake service”.

 

Well after yet another weekend day of laying in the driveway and getting undercoating all over myself, I think I found the issue. Here's a clip of the play in the drivers side LBJ.

I thought I had checked the ball joints by wiggling 12 and 6 with the truck in the air, but by jacking on the LCA and putting a bar under the tire I found this.

 

Looks like that could be the culprit.

 

Sound is still there after replacing the ball joint today . But it had play so needed to be done anyways, and the swap was pretty painless. There's a nice bumpy cul-de-sac near me that I can it to make the noise the whole way around, and I can hear it groan a bit vs. just the knocking kinda noise from before. Which brings me back to the front body mounts. Who the hell knows. At least I know the wheels not going to "kachow" anytime soon.

 

You've got to be kidding me. I just hit these spots (and the other 4 of the same on the passenger side) with silicone spray and it was dead silent on the same road that was making noise the whole way down a half an hour ago.

 

Squeaky hood eh?

 

God I hope so. We'll see on my drive to work tomorrow if I was just (not) hearing things on my quick test drive yesterday.

 

The little pieces of film that are stuck to the hood where the rubber rests were wrecked, slid off to one side by the rubber and you can see where the paint wore through. I pulled them off, cleaned it up, and stuck on some new circles of some 3m ppf I had laying around. Hoping this cures it for a long time.
