High pitched sound under load

Got to go with Ron on this one. I had a very loud squeal when under WOT and found the spider and turbo mating surface was not mated good and when boost went up it sounded like a very loud tight fart.

well I have a weird sound under load that only manifest itself when towing up a grade. I have yet to figure it out. For me it definately was not the fan belt, it would do this when cold, like 20deg out and the fan was not kicked in. It really doesn't follow boost pressure or rpm either. I haven't figured out what causes mine either. So I will be curious as to if you find out what causes yours.

10$ says its his turbo charger.
Next thread: "I just filled up with gasoline, and now my truck sounds funny..."
I drove a 5t with 466dt, and under high loads, an un bearable jet engine clast would happen. Later, realized that all but 2 exhaust manifold bolts were gone....Dunno how that happened, but oh well.

Thanks to everyone! I really appreciate the various concepts. I only have about 72K on the truck. Changed the belt out at 54K.
It is very likely that it is a completely normal sound that I simply fail to recognize. Or it may be the boost. I am familiar with the "swooshing" sound of the turbo so don't think it is that. But certainly could be something has worked loose. I'll check for those sorts of things.
Only have one more trip planned for this year. At end of May we're headed to the Shasta area for a few weeks. Only a couple of places to even expect to hear the sound! It's nice and flat for most of the trip. We're coming up from Bakersfield, CA.
As long as performance is ok and I don't get any warning lights I'll just keep watching very carefully.
Will post if I ever get any sort of definitive answer. Thanks for all the great ideas.

Dennis, the turbocharger is supposed to make a whine during hard fueling. If the sound "gradually" becomes more apparent, thats ok. If it gets louder all of a sudden, that could be something loose.
PS are you a ham radio enthusiest, ?

Parkland,
Thanks for info re the turbo. It does not sound like the turbo sound I'm used to.
Yes. The callsign is KA6TZP. If you happen to see a white 450 truck with CA tags of same with a bunch of antennas that would be me. <G>

I've wanted to get into ham radios for a while, but never went through with it.
What radio makes the furthest distance? Linear amplifierS? Frequency bands? What works good?
I just wish I could put one in my truck, and one at home to ditch the cell most of the time.
Which frequencies give best range? What is the best setup for going say, withing 1000 miles?
Why do you have a "bunch" of antennas?
Sorry for all the Q's, but I'm curious to hear those answered by someone who uses ham's and not a ham radio store....

I built a home-made AM transmitter around 60 watts with 1 single giant (GIANT) transistor, sending data via RS232 computer com ports. I successfully send data over 10 miles using just a couple feet of plain wire, at 9600Bd, but the radios were just CW mode so voice probably wouldnt have gone that far...
I also tried to convert "48 km FRS radio" to a data radio, but it died within a couple hours of transmitting, guessing overheated.
Can i put one of those buggy arials on my bumper? (you know, the 8 ft ones??!?!)
Ha, i'm all excited now...

Parkland,
Now is a good time for you to get into it. The code requirement has gone away and it's just theory and regs that you need to know.

All the good brand radios will do pretty much the same thing. Now a days with the quality of electronics you can't go wrong with any of the big guys. Kenwood, ICOM, Yaesu. Those are just a few of the big guys. For the most part you do NOT need the amplifiers but they do help!
Bands run from the 6m to 80m. The active bands depend on the time of year, day and sunspot cycle plus weather.
I just wish I could put one in my truck, and one at home to ditch the cell most of the time.
That is exactly what I do. I have an HF rig in my truck and one in my trailer. I also have two vhf rigs in the truck. One I use on APRS. APRS is a system that is tied in with a GPS system. It reports my position via Ham Radio to the internet. Click on this link to see my APRS positon:
Where are we? -->Ham Radio locater beacon.
Which frequencies give best range? What is the best setup for going say, withing 1000 miles?
For that range you would want 40 or 80m depending on time of day etc.
Or 2m for short range .... line of sight... type thing. 2m and 440 radios generally also have repeaters set up in various areas. Some of them you can link and talk for hundreds of miles.
Why do you have a "bunch" of antennas?
Counting my car radio I've currently got 5.

I hear you about the store vs user.
Google Ham Radio in your local area and you should get a reply showing various clubs and or organizations that can help you with Ham Radio.
Good luck.
