2006 H2. I pulled off the the skid plate and its still there. Wheel bearings seem ok. Its only on the passenger side. I've searched some and don't think its a body mount, seems more suspension related idk. Anyone else experience and fix this? Would like to know before trying to replace everything lol Thanks!!

 

Bad ball joints can sound like that.

 

This ^
I would try greasing them if you haven't already (and the rest of the front end while your at it)

 

Thanks guys! Ball joints are good and were lubed up, it still didn't help I also checked sway bar bushings and they are good, hmm maybe the shock or control arm bushing idk Any other ideas?

 

If the noise is like a wewewe then 99% is the sway bar bushings .
Got crazy with that noise and ne guy from the tire shop told me about the sway bar
Fix it with this kit ( 03 09 Hummer 2 H2 Heavy Duty Extended 1" Sway Bar End Links Mounting Bushings | eBay)
So happy the wewewe isnt there anymore

 

I just installed all new OEM body mounts in my 03 H2. My banging and noise from front end are now gone and truck rides much better.

 

My squeaks initially came from the rear lower control arms. Replaced them with aftermarkets with grease zerks and the problem went away.


Now my fuel tank squeaks like crazy, hoping to drop the tank so I can see where the hell the noise is coming from.

 

The more I think about it, I'm suspecting a body mount... for those who have replaced them, did you do it yourself, or have the dealer do it? If its it DYI, could I get a little write up please Thanks!!

 

I got it done at dealer. I don't have a lift to do it myself. I tried to find places to do it for me besides dealer but couldn't. Happy with the results though.

 

Sway bar bushings changed ..Road trip 1400 miles and no noise then suddenly the noise came back even worse
now it sound like 2000 squirrels are under the truck
I would grease the sway bushings , if not results then replace the mounts, next step the whole freaking front end ...
NOW I HATE SQUIRRELS
