Hey guys. On vacation right now, but the truck got pretty dirty so I took it by the power washer. Cleaner now I went back to the hotel. As I pulled and and slowed to turn around I could hear this long groaning noise, best described as what a whale would sound like i guess. I thought it was from applying the brakes, but when I backed into my spot it was still making it while I wasn't touching the brakes.

Just checking to see if it could be anything serious, because I got a 3 hour ride home tomorrow towing the boat and I don't anything to happen while doing 70.

 

Possibly your rear end but where is the noise coming from?

 

Can't really say.

Oh, and it isn't constant. It's like I have to move so far in between groans to get it to happen again.

 

check if your e-brake is fully releasing

otherwise I haven't a clue

 

Wet brakes or contaminated brakes.

 

Sounds like a case of wet brakes...........

 

If the noise is coming from the engine it could be coming from the fan. I get that noise sometimes for no reason when the fan clutch locks up even when cool but after a few miles or less, goes away. But it makes the same noise you are describing. When the fan locks up, it's pulling in allot of air, like a tornado, sounds just before it hits you.
