I have a 2005 f150 xlt with 2" drop shackles. When I make right turns at 10mph+ i get an irritating "bed spring" squeak coming from somewhere in the rear of the truck. At first i thought it was the front passenger side wheel area but think now its the rear. It only happens on 1/4+ turns to the right. Started a few weeks ago. I already greased the tailgate and it didnt help. I think now its a suspension componet but can't pinpoint it. Ive checked other posts and can't find any matching my problem. Any ideas on what it could be and any solutions would be greatly appreciated.

 

you sure it's not a brake caliper or rotor?

 

i dont think its the brakes because of when it does it. wouldnt i have to press the brakes for the noise to happen if it was the breaks? Its not a continous squeal or squeek. It sounds like someone doing pushups on a bed with an old box spring. Im really trying to keep the bed analogies pg rated. But the sound is very similar to a more adult rated bed sound. Eeh eh eeh eh eeh eh very high pitched but changes pitch with the bouncing ot the truck.

 

I just noticed backing into a parking spot when the rear tire bumps the curb it sounds like a squeak toy for a split second. What the h-ll is that?

 

it can be your breaks, pull off your wheel and inspect the rotor and calipers and see if your guide pins are greased well and if your caliper bolts are still there. I've lost caliper bolts many many times offroading and you don't know until you start hearing the squeaking obviously.
