The noise in my 93 ES 300 is a rattling noise thats noticable just at slow speeds. It sounds as if it is coming from something tumbling down by the wheel. I will try the gas pedal in park and let you know if I hear it still.
I don't think it has anything to do with the A/C unit. The A/C unit makes a sound like a refrigerator only when it's on, and I don't think it would conflict with the acceleration of the gas and/or making the strange fast rattling sound.
It sounds like it's coming from like somewhere around the wheels possibly and underneath the engine or inside the engine somewhere?
Brando - yeah the sound is also for me only at slow speeds. Like I said around 1800 rpm to 2100 rpm. I'm gonna see if I can make a digital recording of it, if I do, i'll post it.
I asked my Dad (a mechanic) about the noise I've been hearing and he thinks it is either the strut mount is worn and loose or a rubber bushing off of the rack and pinion mount. I dont know. That might be it. I just need to find time to check it out. I will let you know what i find.
If driving and hear rattle noise, it is almost certain that it is the strut mounts. If car is not moving and hear a rattle noise could possible be valves out of adjustment, happens on the rear bank mainly. No rocker arms on these cars.
I have the same problem. A sort of rattling noise when driving at low speeds. I used to work at a Midas shop and I'm going to bring it there during this coming week. I will let everyone know next week if it is the strut tower.
I don't think it's the breaks actually, because the sound isn't made when I apply the break.
Also, I did some more studying on the noise this morning, and it turns out that the noise also starts to surface now when the car is in park and I push the gas pedal.
Around 1800rpm I start to hear the fast rattling noise then it disappears around 2100 I believe.
I was at a service shop, and I asked them about it, even though they didn't listen to the noise, the guy diagnosed it as something not right with the "rocker arms" in the engine.
If you hear the sound when not in gear and not moving it's probably not transmission or running gear. It's most probably engine-related.
Could be lifters/rocker arms; could be any number of things, but noises in the engine compartment are never good. Have it checked by the dealer or a shop you can depend on. These things don't usually get better by themselves. They get worse and more expensive to fix.
My first instinct was that it sounded like a loose heat shield. Then I thought it would be something wheel related due to the fact that the noise seems to coincide with the speed or rotation of tires... Like the rattling was occuring in a cycle. I am not really sure, but wouldn't say the noise is coming from the engine area. This sound familiar to anyone?
Assuming there are no rocks or nailheads stuck in your tires causing your noise, you probably have a CV axle boot torn and over time it has dried out. This causes a clicking type noise especially when turning, depending on how dry it has gotten. You can, with the help of a buddy, jack up the front of the car, put it in drive so the wheels are turning to inspect the noise. I have seen ES 300's do this many times on either side.
