Is there anyway to grease these suckers so they don't squeak? Mine will squeak when they turn on and when you shut the car off you can hear them squeaking as they power down and come to a stop.

Are you sure there isn't a leaf or something in the fans? If so, then I'd talk to someone that knows about electric motors. I'm sure there's some sort of spray lubricant that could help.

Bad bearing maybe? Seems like that's the case with about any type of fan that starts squeaking...

I have a set of lt1 fans on my blazer, they squeak if I let the truck sit a couple days, I have always just sprayed some white grease in there and it shuts them up. Been doing that about once a month since I bought the fans 5 years ago.

Thats the problem when your coolant temps are lowered the fans run alot.
The bearings are prolly worn, not many options there.
I know I used to drill the rear bearings out (dimple on the backside of fan case) on the older cooling fans, inject a little grease w/ a needle tip gun & reseal it w/silicone.
It worked like a charm.
Never tried it on the newer ones though.
