GEN 2 High pitch whine

[Jon T]

Hi all, I have 2018 Raptor, truck has been great. I have 86,000 miles on it and bought the truck new. About a week ago I started hearing a high pitch whine. It’s most noticeable when accelerating and slowing down. I have also noticed my high speed radiator fan is on a lot more then I can remember. Any insight would be much appreciated. I love the forum thank you.

One easy thing is to grab the rear diff yoke and see if it wiggles or seems to have excessive play.

Tell your wife to be quiet?

:-D

does the whine ever stop (from the truck, not the wife)?
happen only in 2h or in 4a as well?
happen with fan and stereo off?

Have phasers been done? May be your fan issue with engine running warmer than before, I had a sticky thermostat that is common after they pull apart the cooling system.

Did you ever figure this out. You are describing exactly what I am experiencing. 2018 just started making the noise at 85,000 miles. For me it is a whine that changes pitch depending on the speed and really noticeable coming to a stop. No change between shifting gears, same sound in 4A. Has it gotten any worse for you? Thanks!
