Great pictures! Just goes to show you you can not trust a grease monkey! My H2 has 90K on it and the upper idler (the one in the mirror in your pic) had never been greased. It was replaced at 50K under warranty. I changed it to a 90 degree zerk and am greasing it myself from now on. They have to take the skid pan off to get at this one and that is how they stripped the threads out of the frame with their air gun! The torque on the UCP is only 22 ftlbs according to the service manual.......that is not an impact gun torque.
Thanks for posting again. Bet I am not the only guy in this position!

Excellent thread. I just got to these this weekend, but I wasn't able to figure out how on earth one can get to the one on the upper idler arm. I guess you have to unbolt it to access it? Will change it to a 90 deg zerk then.

Re: grease fittings location
 

These were to be changed out to 90 degree ones by the dealership on the early models when they came in for lube and oil change. I just went ahead and did it myself by un-bolting it and putting a 45 degree in (seen in the picture) since I was doing all my own work on ours.

Good luck, Ed

Re: grease fittings location
 

Interesting. The H2 was serviced by the dealership since new up until about 60k miles. I'm not surprised they didn't change it. I haven't had a good dealership experience yet.

Do you remember the thread size for the replacement? I'm guessing 1/4"? Thanks!

Re: grease fittings location
 

Looked in the garage "automotive junk drawer" (I never throw anything away that I think I may need) and did find a straight out zerk that has a tapered 1/4-28 thread. I would say that would be the correct size.

Good luck, Ed

EDIT: Would need H-109-A

Thanks Ed!

Re: grease fittings location
 

The idler arm on the HUMMER H2 has a grease fitting near the top end of the shaft facing the right-hand frame rail. Access to this fitting is very limited and may be accomplished, although not easily, with the use of a 90? grease gun adapter. However, to assure an adequate lubrication at each maintenance interval, it is recommended that the grease fitting be replaced with a 90? style fitting, P/N 09417903, pointing upward.

Re: grease fittings location
 

That's the gm bulletin, not a mandatory replacement but a recommended one. I do believe if my memory serves that it was a customer pay item as well.

Re: grease fittings location
 

oops, my bad ;-) Thanks HUMTECH

Re: grease fittings location
 

Thanks ya'll. I was able to find the TSB. Seems like the GM P/N for the grease fitting is no longer available or the ones that I have found with that P/N are $30 and above. Not paying that price for a grease fitting. I ordered the one Ed posted above.

Re: grease fittings location
 

Got the grease fitting today. Would ya'll recommend any loctite on the threads? Should I be worried that the fitting won't be sealed?

Re: grease fittings location
 

No Loctite, jst screw it in snug they can break easy if over tightened, it wont need to be sealed just snug it up

Re: grease fittings location
 

If you replace your idler arm get a MOOG and it will come with a nice extension tube you can zip tie right up front for nice easy access with your grease gun.
