creeking noise

i have been having a creeking noise in the front end. everything up front is new except the springs. i recheck all the control arms and retorqued them. well today i got under the car and had my son turn the wheel. i could feel the creeking in the idler arm but when i went to greese it i could not get the greese gun handle to squeeze. so i took the zerq fitting out put new one on same problem. but if i backed ythe fitting out a couple turns then i could get greese to go in . weird. the creeking went away could not take it out it started to rain big time. by the way it is a moog part . has anyone had a problem getting greese in there idler arm?
