2007 hummer h3, when I shift from R to D to P any of those 3 the car like nodge hard like you can feel it and make like clung noise when change the gear. I looked under it, I can see where the gear shift. and the big noise and clung coming from there.. I just noticed how hard like it kick when staying still and changing gear. should I be concerned? and how can I fix that?

 

I'd check the center mount under diff as well as engine mounts and trans/tranfx mounts.

 

How many MILES????? Are the U Joints still originals? Front Drive Shaft CV Joint still original?

And check that stuff per HH above.

 

engine mounts are good cus I checked them when I rebuilt the engine
and the under def mount I put a new cushion so it shouldn’t be clunging . It just happen when I switch gears and it come where drive shaft like connected to the def

 

roughly 130k
Drive shaft is original
U join original
cv axle are new but the I think the actual shaft is original

What you mean by hh?

 

HH = Happy Hummer

Not talking about Half Shafts (CV Axles). Your front drive shaft has a CV at the T Case, and it will clunk and make noises telling you it needs attention... like come LOOK at me....

 

oh yes I def want a happy hummer lol and I think I know what you talking about it’s basically where the drive shaft hook up to. Does that make that huge clung noise and shake the whole damn car when you shift the the gear? Because I can see the drive shaft like shift/rotate when I change gear and that where the sound come from like that area. does this have to be replaced alone or it like the whole drive shaft basically ? And when I take it off ? Is that differential fluid that will come from there ? Just so I know what to top off

 

Take a look

 

nice but see the cv you talking about is in the back of the truck the sound I hear is making here it’s connected right next to the oil pan infront. And there is no cv there

 

No, but there is the front U Joint.

Grab the front drive shaft like it is your pay check and try to move/wiggle/rotate it and see if it makes noise. If the rear CV Joint allows play, you can hear that in the front U Joint as well.
