Who knows then.
Like I just said. I reckon it's a worn spindle.Who knows then.
Either drive it until you break it or fix it until you break it.
I choose drive it.
No not the trunnion bearings (I’ve replaced those), I’m talking about the pin in the top steering knuckle cap or the pin in the bottom steering arm (that go into the trunnion bearings)No kingpin on the 80 series, maybe you meant trunion bearing?
I have a feeling this is something simple like an exhaust hanger.
I feel for you though, I hate noises, rattles, clunks, etc..... I really hope you figure this one out. If you were close to me I would come try and help you find it.
Motor mounts????
Wouldn’t engine mounts make a noise on acceleration or deacceleration rather than shifting right to left or left to right?No not the trunnion bearings (I’ve replaced those), I’m talking about the pin in the top steering knuckle cap or the pin in the bottom steering arm (that go into the trunnion bearings)
Clutching a straws now
You would think so, but if this were my rig I would be checking everything at this point.Wouldn’t engine mounts make a noise on acceleration or deacceleration rather than shifting right to left or left to right?

I don't think Wits' End, Solutions for Problems You Didn't Know You Had - https://absolute-wits-end.com/ sells clunk stop kits other than bushings.......Thanks for everyone’s input but it’s none of the mentioned things.
I now suspect a crack in the frame but can’t find it.
i know there are speciality services that can find cracks but are very expensive.
I would have though a crack in the chassis loud enough to hear it clunk would be easily found.
ive tried prying on everything!
totally at wits end.
Thought I’d post an update since I invested so much time and effort to finding this bastard noise.
well I’ve found where it’s coming from.
The chassis/frame near the cross brace rod appears to have a crack down the weld. You can sort of see from these endoscopic camera down the frame rail (inside).
if I clamp the frame like I’ve done in the pics the noise isn’t there anymore.
im hoping I can just grind the frame where the joint weld is, then re-weld. Thoughts?
