so i wrote about this chirping that you would hear when the vehicle was cold and then would go away after just doing around the block and would not come back till the vehicle was in a cold state (motor and weather wise) so i was doing the water pump because i had never done one on this runner and when taking the fan clutch of and the fan idle carrier i found it was this that was making some noise so me and my dad had drilled into the center of it tapped it and put a zert fitting in it. and then popped the top seal of the bearing and packed it and now as quiet as could be. i'm stoked. so hope this can help someone else.
