This is so simple it really doesn't deserve a How-To, but may help someone new to Jeeps or new to working on vehicles in general.
I started hearing a squeaky/rattle sound near the front of the engine while it was running. I suspected it was the idler pully based on where the sound seemed to be coming from and the fact that the tensioner is less than 2 years old and the water pump is less than 3 months old.
Using an automotive stethoscope, I slowly and carefully fit it between the spinning fan and spinning belt and put it on the head of the bolt. All kinds of crazy noises were coming from it.
Ordered a MOPAR idler assembly from Amazon . It came with the spacer, pully and bolt all completely assembled.
Loosen fan belt,
Remove old pully assembly using a 14mm socket,
Install new assembly and torque to 35 ft/lbs,
Reinstall fan belt.
