Grease fitting (zerk) help needed!

[finall]

Just found the well-hidden 11th grease point on the upper part of the idler arm. Need to take off the front skid plate just to feel it with your hand. Can't see it at all, as it is recessed in a well of steel around it.

Impossible to lube, as it has a straight fitting, with about 1/2" space around it before it contacts a wall. I need to replace it with a 90 degree fitting. So I took the nipple off. But my 90 degree zerks (grease nipples) do not fit.

Anyone know the thread pitch on the grease fittings on a 07 H2? There are hundreds of sizes available in metric, standard, self-tapping, etc.

I called the local auto parts store, and they don't know. Help!

I figured it out. It is a 28G (standard) or 0.9 (metric) thread pitch. The two are almost identical, so either zerk will fit.

Dealer will replace it for free during oil change, if you ask....
