Yukon Engine Noises

[geeeoff]

Hey folks - this odd noise almost a chirping more than a ticking started yesterday with my Yukon's engine. The rate increases when revved. I thought it might be a lifter but seems like that would be more of a ticking noise than this.

Could be a bad bearing in one of the front pulleys. Take one belt off at a time and see if the noise goes away.
