Default electric fan squealing

Having occasional problems with my 99 ls1 f-body fans squealing. Mostly at startup, not always both, usually eventually stops, many times stops by slapping top or rad cover. I,m assuming dry bushings.
Any one else run into this. Found nothing on search.

Next time you get a chance when its cold, before you start it open the hood and spin the blades. See if they squeal then and go from there.

Mine have been making a light squeak/chirp for a long time, but it's really light. But I also know they will seize before long, then blow the fuse and i'll have to replace the parts then. I would now but it the car rarely leaves the garage anymore.

My 99 ta does this every time I start/ stop the engine, and its getting louder. I can hear the fans cycling on and off at idle.

I'm sure replacing the fan motors would fix the problem. When I don't hear the noise anymore, or If engine temp rises, or if the fuse blows like said above, I will update with what I did to fix it... I'm expecting this day to come soon.

Was told on another website this is usually an end play issue in motor , Which explains why mine is a nuisance noise that goes away, sometimes just restarting or slapping the radiator core hard. Haven't tried to see if I can disassemble yet, but doubt it. Advance auto listed rep motorsDORMAN # 35379 @ $46.79ea.
