Hello, I posted a new thread a few days ago about a problem I am having with my jeep and didn't get one reply. I really would like to get some help. Here is the problem: After my jeep warms up, which is about 5 minutes driving, it makes a whistling/squeeling noise. The noise isn't that loud when driving in gear and accelerating. When I let off the clutch it makes the noise very loud, it makes the noise even when I am stopped, but will go away within about a minute after being stopped. When sitting at a stop the noise will get louder when I rev up the engine in neutral. The noise is extremely annoying and I hope it isn't an actual problem with anything. Can someone please point me in the write direction.
I don't think it is the throwout bearing, but not an expert. I had a 73 cj5 with a thorwout bearing going bad and it made more of a chattering noise than a whistle. I do know the noise if coming from under the hood. I don't have deer whistles and I'm not a deer, but thanks that would be cool. The noise does not start until the engine is warmed up. The noise gets louder when I rev the engine when in neutral, it still does make the noise when in gear but doesn't seem as loud. When I am sitting at a stop at idle the noise goes away in about 30 seconds. Thanks for help.
If letting off the clutch makes the sound worse, I'd guess the Throwout bearing also. I don't see how a idler pulley would be affected by the clutch. An idler is very easy to diagnose. You should be able to pop the hood and tell if the noise is coming from the idler. I use an old stethescope to listen for noises under the hood. Found a bad bearing in my truck altenator recently with it.
Ok so having the clutch in or having it in neutral has the same exact effect on the noise, the noise isnt as loud when there is actually a load on the engine. I hope it isn't the throwout bearing, I like the stethoscope idea, I need to go pick one up. The noise almost sounds identical to someone whistling, thanks for the help.
