The idler arm requires lubrication at the recommended intervals specified in the Owner's Manual. However, the zerk fitting is apparently not visible and readily accessible. The underbody protection plate on the vehicle (the one embossed with H2) needs to be removed. The idler arm zerk fitting is facing the right hand frame rail of the vehicle. Therefore, a 90 degree fitting on the grease gun is required. The Snap-On part number for the grease gun adapter is YA757.

Lubricate splines
"Inspected Driveline and found the splines need lube."
This is the one most likely similar to yours.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> Happy New Year Everyone,
Just wanted to let everyone know that I had to replace my throttle body and the back half of my transfer case and drive shaft (all of which was covered under warranty). I had some problems with my throttle sticking at about 2000 RPM and I had that "clunk" whenever I accelerated from a slow roll. Not from a complete stop, but from a slow roll. Brought the truck in for an oil change and explained the problems to the dealer. They knew about both of these issues (other H2 owners have had the same problems) and both were fixed in a day. From what I understand, the current driveshaft was a little too short and a longer driveshaft was installed. NO, bad jokes here.. :-) There is a HUGE difference now that the driveshaft issue is fixed. Wish I would have had it fixed sooner.
