My Jeep makes \"Bird-like\" sounds when at high RPMs

It only happens when I put a good load on the engine, say when going up a steep freeway hill at 70mph, The noise sounds like a bunch of chirping parakeets or something...[img]/wwwthreads_images/icons/smile.gif[/img]

It goes away after about 30 minutes. And It is GONE out of town gone. Then when I turn off the car, let it sit for about a day, the noise comes back? at first I was suspecting the front driveshaft maybe was spinning fast enough to vibrate due to the angle, and actually touching the header pipe(only about 1/4 inch away). possible?
Who knows..
Its an 87 wrangler with a 258 and an auto tranny..
Thanks.

Re: My Jeep makes \"Bird-like\" sounds when at high RPMs

After driving, check the u joints by hand to see if any are hot. Mine made chirping noises as I pulled away from a stop when the needles went bad on one cap. That cap was noticable warmer than the rest when I touched them by hand. Heat = friction (or is it the other way around?)

Im going way out on a limb here. But my throw-out bearing in my TJ is chattering a lot. At first it only did it in the morning (after sitting).

Re: My Jeep makes \"Bird-like\" sounds when at high RPMs

i'd like to know what you been smokin, cause i want some too

chirpin like birds? ha ha ha

it's not pinging is it- detonation? you know that sound right? when you put a load on the engine as you said, it would ping then. BUT it wouuldn't go away unless it was bad gas and you put some good in or you retarded the timing.

hmmm, let me head on down to the pet store and listen to a few parakeets was it?

Re: My Jeep makes \"Bird-like\" sounds when at high RPMs

Is it a serpentine belt? When it is cold outside the belt on my 460 Ford will sound like a bird until it warms up.

Good Luck!
