I had this happen on my Airborne revolution. Since new it was squeeling. I suspected that the dealer did not lube when installed and I was correct.
Mine has 4 bolts on the top of the pivot shaft, then the whole front drops downs. Grease that shaft with a nice thin layer of grease. You have to check the instructions on yours, mine said to torque to 150lbs to set it in place then back out and retorque to 45lbs. For the first few trips after I re checked the torque until it stabilized.
Not one peep of noise now.
