Ok yesterday my ( it sounds like the rear end area ) started squeakings when I take off. But ass soon as I start to slow down it starts to fade out. When I accelrate it starts again.. you get the point. What can be causing this? I guessed wheel bearings? any other ideas?

could be as simple as replacing the u-joint... get both wheels off the ground, put it in neutral and get the tires spinning, or you might have to have it running in gear to make the noise happen... either way, you should be able to pinpoint the noise...

ThanksWill try that asap.

Just make sure you take the proper precautions when running in gear... do it on a flat surface, block the front wheels in front and back of the tire, and have someone around to shut it off if necessary while you're having a look...

Might be that anoying center-support bearing (if you have one). Sometimes when that rubber boot wears out it starts making funny noises. Either that or you've got metal-to-rubber contact.

If it's a metalic sounding squeak but it's not constant it might be your brakes. Sometimes when drum brakes get old and they heat up due to several quick stops the material can shear off, and get melted to the inside of your brake drums over time. It will squeak until you put on the brakes. I know it sounds funny but it's happened to me before. Sometimes it gets so bad you have to have your drums re-turned.

Other than that wheel bearings would howl ALL THE TIME. You'd get no peace whatsoever. If it's in the rear-end it will get worse over time until you start getting vibrations. If that happens I'd guess your pinion bearing or your carrier bearings.

Lubricate thouroughly with Preparation H. If that doesn't work, best way to check your u-joints is with a prybar with the tranny in gear and the wheels locked. See if the u-joint moves. I would guess, thought that it's a wheel bearing. Take em out, clean and inspect if you can't find anything else.

To me it kinda sounds like a belt squealing. but when you goto stop, the noise starts to get quite until you actually stop. And now that I think about it, when you take off easy it makes more noise. When you take of faster kinda like not really punching it down to the floor.. but kicking it in the ass to get it moving it makes less noise.

That doesn't sound funny.... My front drums were like that. That's another reason I did the disc conversion. lol not too cost effective is it?
