My jeep is squeking when driving. not a suspension squek it is constant while in motion. its not the brakes dragging or squel pins. any ideas?

 

mine did this and it was my front output-shaft bearing in the tcase,i unbolted my front driveshaft and with the weight of the driveshaft off the bearing,it stopped squealing.
go under ur jeep and turn ur front driveshaft,if it squeals its the bearing

 

mine does it sometimes and not for to long seems like it when it cold would it be the smae thing or a belt?

 

Bad axles u-joints can cause a squeaking that will speed up and slow down as you accelerate and decelerate. Reach up under there and grap the yoke right behind the steering knuckle and "jiggle" it around. If it moves...your u-joint is bad.

 

mine did it at slow speeds but the faster i went the less i could here it

 

+1 for a loose belt. Mine is doing the same thing. Does it get louder when you turn the wheel at low speeds? If you try turning the wheels while stopped it should make it squeal more because of the higher load on the power steering pump.


Also Hyper, after your belt warms up it gets better grip on the pulleys which would be why it squeals more when it's cold. Cold belt = less grip = more squealing. I'm not sure if the expanding and contracting could be a variable as well, but its a possibility.

There are a few threads about tightening up your belt, I think the adjustment is by the power steering pump. I'm not sure how tight to go tho.

 

possibly the mufler is making noise. Mine makes a good squeel when I first start going and I could see how it might make a constant noise if it was any more loose. to check it you can just wiggle your tail pipe or try to move your muffler around. where does the noise sound like its coming from? Front, back, etc?

 

my 99 did this mechanic told me to use a needle fitting on grease gun and inject grease into the ball on the double cardan joint on the front drive shaft just in front of t case, worked for me.

 

Check the front driveshaft. Jack the jeep up and spin the tires by hand and listen for the squeek

 

ok will check front drive shaft and u joints thanks. no its not the muffler and not a belt o know that for sure.
thanks for all the suggestions
