BAD Front suspension noise from 20-40km/h

I just noticed a weird chunk noise, similar freq as rock in the tire but there is no rock. I can clearly hear it between 20-40km/h but gets drowned out by driving noise over 40. Could this be a bearing? CV axle ? I mounted my go pro to get a better idea of what is going on and uploaded the vid.


any ideas ?

Anyone? Ideas?

 

sub'd... is there snow where you currently are?

 

Not right now but yes.
I'm going to take it for a drive to my buddies house and listen again

 

I would check the tires for nails or rocks first.

 

U - joints maybe? Buddies truck "clicked" when in reverse and the u joints were bad.
Rotate your front drive shaft and see if there is any play in it.

 

not a rock nor a pain.
I have a feeling its something to do with the Cv axle going into the diff but I'm not sure what it could be. It was fine, came back from holiday 20 days later first drive and clunk clunk clunk but mostly between 20-40. Powered or coasting, 2 wheel or 4/

I'm mounting my go pro tomorrow and recording the Cv axle, as i checked the front hub/bearing for slop and thats fine

 

i have attached a video,
I really hope some one can help me out!

 

Idk it could be so many things from the wheel bearing to the diff...

 

yeah, when i jacked the truck up there was no Slop in the wheel bearing.
All i know is, I'm FREaking out.
Im most likely pulling it all apart again today and see if i can SEE anything wrong after i pull on everything a bit.

 

gonna drain the oil in 10 min, ill update this then if i can solve it, a call to ECG.
Diff is only about 500km old after install

Drained the oil, since this is the first oil change i was expecting some metal filings,
barely any present so thats a + but still baffles me as to what can be making that noise.

CV axles and hub bearings next
