The newest banging, clicking, rattling coming from my truck.

Hello all,

I have an 09 Taco 4cyl with standard everything. There is nothing extra on this truck. Mileage is 11,500. I have been driving the truck all day today and I stopped at home for a meal in between classes. The truck was sitting for an hour. I got in it, started the truck and there is a new, intense, high pitched hissing coming from the engine. The noise level goes up and down as the engine revs up and down during shifting. The noise isn't crazy loud, but definetley loud enough to hear. It's like a high pitched humming sound. What could this be??? I'm pissed...i've had this truck in the shop on numerous occasions for different things. I like the truck but come on!! ya know?

Anyway, thanks for any help you can give me.

 

Clutch throw-out bearing????

 

the truck is an automatic if that makes a difference....listen i know i'm being vague but maybe someone has had a similar occurance. Maybe its not even a bad thing.

 

i would take off the belt and see if it stops,then you may have an idler,tensioner,alternator noise..also i would check the power steering fluid..if its low,it could cause a cavitation sound in the pump.

 

ok so i know this may sound retarted but i have heard a sound like that in my truck (08 single cab auto trans) before.....it was the radio/speakers. i guess for some weird reason my radio/speakers were picking up a current or soemthing from im assuming the alternator? and it would cause i kind of high pitched humming noise that was just lound enough to hear. it would get lounder when i hit the gas and get quiter when i left off the gas i know it sounds weird but it also happened in my 92 mercury grand marquis.

so if it happens again try turning OFF the radio maybe thats it?

 

^^ yeah man..that happens..rarely..but i have heard of it happening as well..some thing with grounding or some shit

 

haha ok well i glad that some ones knows about it too. but its really weird but it goes away havent heard it for a long time. actually since i switched out my stock radio for an aftermarket one...

 

yeah that may be why you havent had any more issues with it...i was having issues with my stock radio changing stations on me while i was driving..im not sure..it was the weirdest thing

 

ya that is weird well i changed mine cuz i want to get an amp and sub sometime when im not broke, but my radio kinda did weird things too like that noise and cd's would always get stuck i would ahve to bang it to get them to come out haha.

 

ouch..well at least you got a new system..lol

 

My thumb was hitting the steering wheel station selector and/or volume. This was my first vehicle with controls on the steering. I thought I had an electrical problem at first. Ooops

As for radio and electronic noise, my Blackberry talks to my radio and causing all kinds of noise if they are close together.

 

hahaha.."talks"...but yeah thats understandable
