heres ANOTHER situation im going through (refer to the brakes section, if your interested in hearing the other). i really didnt know where to post this so im posting it here. about 2 months ago i installed a Belltech drop kit 3/4, everything was fine for about a month, then for the last month ive heard this squeeking, kinda like when you sit on an old matress, coming from the rear of the truck. the noise happens when i accelerate and when i come to a stop after breaking, its like the end of the truck dips down when i accelerate and the noise goes off, when im done brekaing and the rear goes down it makes the noise again. its really beginning to bug me and its embarrasing. i took it to Coral Gables Ford and immediately they were like "ohh its dropped, where not even gonna look at it" i still have warranty on the truck, btw. if anyone can supply me with any information or solutions it would be greatly appreciated. just today i was chekcing the lugs on ym wheels and when i turn them tight that they cant go any tighter i began to move the truck back and forth and the noise began again. im thinking it might be the leaf springs, but again i dont know much about anything. again any help would be appreciated. thank you

*Edit* one month update, the noise is back WD-40 works for about 1 month, then the noise comes back. any help or first hand accounts are appreciated.

 

Try looking at the plastic inserts at the end of each leaf spring. My truck did the same thing. They are a b*tch to change, but it works. The plastic inserts are like 12 bucks for a pack of 4. Mine wore at about 50k miles.
I don't have a part #.

Good luck

 

Mines doing the same thing. it has gotton real bad in the last week and a half or so. Its a 98 F-150 XLT 4X4 with factory suspension. The only difference with mine is that the bottom spring on both sides is "turned" for lack of better words. Both ends arent touching or lined up with the other springs. It is annoying and embarrassing.

I dont look forward to loosing up the U-bolts and straightening them out cuz I know some will break (my luck), while I'm at it I'm gonna replace those plastic inserts (thanks M1j).

My right front is also squeaking real bad, I jacked it up and I also have a bad upper ball joint. Dont they make anything with grease fittings anymore?

 

i dont have any problems with the front, its my rear thats nasty. im thinking its the bushings maybe? i greased them all up again with silicone.
