hey guys i have a 2002 F250 5.4. 149,883 miles.. When i accelerate all i can hear is a squealing noise. its annoying as hell. as soon as i take my foot off the gas it stops.. it sounds like a loss clamp on my exhaust but its not there all tight.. i cant find it anyone have ideas.. any places a can grease maybe..? its coming from the cab back. not in the front end.

 

Serpentine belt?

Water pump?

Alternator bearing?

Air conditioner compressor?

 

Try accelerating a little more slowly, it'll save $ on tires also. Sorry had to do it.

 

Squirrels?

 

Not in the front... Its not how hard i accelerate it just does it when i put any pressure on it. it squeals louder in first and second then quiets down at a low rpm.. its weird it comes and goes.. but its been doing its alot lately. i feel like something is looss im gonna have to get another hand this weekend and FIND IT! btw just drove 10 miles and it didnt make it.. but it did all day today

 

Nevermind, just saw where you mentioned its coming from the rear...

 

Carrier bearing?

U-joint?

 

Same thought as redford Carrier bearing. I had one that would squeal when under acceleration and had a real hard time tracking it down until it let go completely. I thought that I was going to loose the drive shaft before I could get her stopped.

 

this morning it was real quiet and it was just ideling. this is aggervating

 

That takes the rear part of the drivetrain out of the equation. Have you ever replaced the idler pulley or belt tensioner? I've had those go on my 2000, started out as an intermittant squeal but then became worse over time... They're pretty inexpensive to replace if you go that route (might as well do the belt too if you end up replacing).

 

KoolAidMan888 i sent you a private messege i have the same problem your having. Do you have a 1 piece drive shaft or 2 piece with a carrier bearing?

 

What was ever determined to be the cause of the noise? Mine just started doing this. It's also vibrating at 55 and above. I have had the tires balanced twice. I think it is drive shaft or brakes. Ideas?

 

Mine ended up being the U joints on the back drive shaft. Replaced them and no more noise !!!

 

Is that something you did yourself? Do you need a press? I just crawled under mine, and it has some slop in the rear and looks like even a piece has sheared. How much did it set you back if I may ask?

 

I did the job myself. The U joints cost about $12 a peice. I didn't use a press I had a ball joint C clamp I used and had no problem at all.
