Abnormal Chirp or Squeak Noise from High Pressure Fuel Pump

Hello Folks. 1681 miles on truck. I started hearing a chirping sound. i can not hear it with windows up but down its real annoying. I am thinking a pulley? let me know if anyone else hears or heard this on their rig. I made 2 videos. One goofing off with suspension stuff around neighborhood where you can hear it and one with the actual Chirp trouble.

Suspension movement and me talking to USPS about a stolen package.....

Thats funny. I thought I was hearing stuff on my truck but Im experiencing the same issue. Very random though. Its hard for me to duplicate the issue so I feel like its useless to go to the dealership unless I know how to get it to chirp when im actually there.

 

Mine makes the same noise.

 

hmmmm funny that I am not the only one. Seems at around 500-600rpm

 

Belt looks like crap..Idk Cheap?

 

For anyone watching the 2nd video, skip to 2:40.

 

I seem to only hear it when i first start the truck and windows are down

 

Toyota, made in China.

 

Lol. As most say. I say built in Texas =)

 

bearing on a pully, for sure

 

Mine does the same thing. Seems to be when the A/C compressor cycles.

 

That's what I am thinking. Couple more people with the same problem

 

Maybe I'll try to turn ac off and see what happens. I might try to spray the pulleys with synthetic grease and see which one quits making noise, if it does.

 

Let us know if that is a fix!

 

Check idler and tensioner pulleys. Use a mechanic stethoscope to narrow it down.

If your A/C compressor squeaks you need to check the compressor our asap.

 

Will do guys. I'll probably get some spray tomorrow and I'll check it with ac off

 

Can't hear the video at the moment, but D4-S is known to make squeaky noises because of the high pressure fuel pumps.

 

Hard to tell from the video but it sounds like the AC compressor turning on and off. Normal sound.
