can anyone help me up with the part number here.
what the part number of the plastic cover on the front bolt nuts?
photos attached

 

Don't know. I have owned an 06 and an 08 and neither had those on them.

 

i have a 06 and did not have them,ask the dealer

 

Same here, 07 and no nut covers.
What's wrong with letting your nuts show, sic?

 

cause the car came with it. so since my dog bite it off. i was thinking to replace them with new ones. its just feel more comformtable of having it like new. hahahah

 

found these on www.japanparts.com
hope its helps for those who need it.

 

Wouldn't those promote rust by sealing in moisture?

 

Don't think so. there is 6 small tiny drain/drip on the cover back.

here is how the package looks like. it cost me 4000 japan yen for 4 pieces.

 

I would not bother with buying more of them, they will just keep flying off and the money will keep flying out of your wallet to buy more. Just more undeserved income for GM for poorly designed part. Great Hummer, bad part..

 

It's $1.35 for 1 cap at www.gmpartsdirect.com
