Listen to the sound right after it starts up..

 

hahahaha! yes a cat stuck in the motor wouldn't be good, even if it was dead i'd beat it up for messin with my engine. I PITY THE FOOL WHO MESSES WITH MY TRUCK. anywho, the screeching noise, I tend to sometimes drive in OD on the streets and I dont normally hear a screeching sound; I'll drive like that on my way to work see if I hear anything. I know that when I'm in OD sometimes, when I touch the gas after letting up (while moving) I'll hear my driveshaft kind of bump when I start to accelerate more, but no schreeching.

 

yup. sounds exactly like mine. could've been mine, even. i'm interested to learn what that might be too.

 

mine doesn't.

well, i shouldn't say that. it never did it before the recent cold snap hit. now that it has started doing it, t may do it once it warms up outside. i'll let you know in a week or so when it finally gets above freezing.

 

Nope, just cold.

 

Didn't listen to the video/sound clip, but I know what you guys are talking about....my truck did that today (twice) actually

Can't do anything or change it obviously...oh well....that's what the warranty is for

It's only when it's REAL cold out anyways

 

My 4.7 does it... My '01 4.7 did it as well. Not sure what the cause was, but I've heard many ChryCo cars doing the same thing.

Almost wish it would do it 100% of the time - it sounds MEAN

 

it doesn't sound mean. it sounds like my truck's in pain and it's crying out for help.

it seems like the temperature breaking point is around 20...it was right around there last night when i left work and it didn't make a sound.
