|lldw||I have the same thing with my 2005 unlimited. Just bought it used with 74000 miles. I was told it was a torque converter problem.I had that replaced and also some transmission upgrades. for a $1600 bill. AND it did not correct anything!! Whats next?|

|Zdrisko||My '98 does the same thing. I figure it's the pilot bearing or shaft bearing. I'll find out for sure when I replace the clutch.|

|JeepCats||Mine is definitely related to acceleration. The pitch increases with acceleration an the second I lift off the throttle it stops or dies down. Some keep trying to say it is tire noise because I have mud terrain tires but this sound was there before I change tires. Plus tire noise would not be tied to the accelerator.|

Either of you tried raising all four wheels off the ground and running thru the gears?
Staying in the same gear and laying hard on the accelerator increases the pitch of the noise?

|JeepCats||Was it u joints. I have a sound that fits you description. Definitely only there when foot is on the gas. It instantly goes away if I lift off gas. Everybody keeps saying it is tire noise. They clearly aren't listening. Tire noise would be related to tire rotation not torque. I'd been told Rear diff issues, CV joints, fluid levels, you name it. It is clearly related to the torque being placed on something. My noise is noticeable to me at 45 mph. It gets louder and higher in pitch as the speed goes up. I changed ujoints recently on rear shaft when replacing pinion yoke and seal. I think this was going on before and after that repair.|

It could. I've replaced one on my Jeep so far, and the only way I noticed it was bad was it would start making a noise at around 25-30 MPH.
I'm not saying the U joints are the problem, just a good place to look first.

More info: the Jeep only has 45,000 miles on it too.

I'd check the U joints for wear. what you described sounds exactly what to expect.
U joints are very simple and cheap to replace yourself, and finding them to be bad is pretty easy if you know what to look for. you can Google, search, or ask around here for help on identifying if they are good or bad.

|PTaylor||More info required. where is it coming from? The engine compartment? Under the Jeep? Rear? Left Side? right side?|

Noise when accelerating at highway speeds
I'm having a pretty annoying problem when accelerating at around 55-65 on the highway I start to hear a high pitched whirring noise, only when hitting the gas. When I let go of the gas, it goes away. It only seems to make the noise around this speed range. Has anyone ever experienced this and fixed the problem?
Thanks in advance for any help!
Some info: 03 Sport, Stock suspension, 31" Tires, everything else is in pretty perfect condition.
