loud squealing/whining while turning right

[ldyzluvdis06]

i have a 03 f150, 5.4, 4x4. anytime i turn right i hear a squealing/whining from what sounds like the back of the truck. it's only when i am NOT accelerating. if i hit the gas pedal at all, the sounds goes away. any help with what the issue could be?

I don't know if the F150 has u-joints in the front diff or cv's. If it's u-joint check the ones at the wheel, they're failing.

sounds like the rear diff is going out... does it sounds like tires squealing?

no, is sounds more like springs in a matress.

Check all ujoints. (guessing you'll find one of the front axle shaft or driveshaft ujoints dying)
Check diff fluid level and make sure its fresh. Maybe the additive has seen better days.
Check leaf spring bushings, if greasable, give them a small shot.
What diff is in it? Locker or LS?

I'm with eagle on this... Maybe try spraying lithium grease on the leaf spring shackle bushings

Yes. My first thought was ujoints or leaf springs. Would the ebrake be part of the problem? You guys know more than me. God forbid a girl says something.

e brake or rear drum brakes in general could do it... but I would think there would be other issues/noises along with it... but you never know...
