Strange Noise at Initial Roll Out.

I have a strange almost like fluid squeal sound coming from left front of truck when I place in gear and start rolling. Sometimes about 3 seconds, up to about 10 seconds into the roll out. Very strange as it could be confused with suspension squeak, but its happens on flat ground with no movement of suspension. It happens every time I roll out the truck after anything more than about few minutes of engine shut down.
Anyone experiencing this? I'm thinking it's maybe the steering pump.

 

If its the ABS self check clunk everybody's does it

 

Ahhh, the dreaded ABS clunk. Completely normal, mine does it every time. You would think the nerds at Toyota would be able to design something a little less....clunky...

 

So, that's what that is. I have also noticed it.

 

Is it a clunk or squeal?

 

I’d say more clunk than squeal, so I’m betting ABS mentioned here

Ah! Glad I ran across this thread. My first thought is always "It's a rat!"

 

The ABS self checks once moving forward, at about 6 to 8 MPH. It is a clunk sound, like someone knocked on the firewall once.
It's not a time thing, its a MPH thing. You can play with it and tell if its it. Keep the truck at a creep, you can go a mile and not hear it. Exceed 6 MPH and you'll hear it.
