Searching for a noise sounds like road noise...
I have a 2k PSD 7.3 4x4 with about 300k on it
I have only had it for about 6 months and have not gotten much past filters and some general looking at the suspension so at this point it could be just about anything making this noise.
My story is the other night getting on the highway, empty bed standard evening goin about 55. As i went from the onramp (concrete) to the highway (asphalt) i heard what sounded like the road had been ground getting ready to redo. I went about a mile and thought that it also felt like the truck was dragging excessively and was worried i had picked up something around the axle. It was night and i looked all over and did not see anything, got back on the road and the noise was gone so i thought maybe it fell off when i slowed down.
Well the next day i was on another onramp and when i hit that steel expansion joint again the nose was back, this time i could tell drivers side, but as i turned off the radio and rolled down the windows it went away.
I could get it to come back if i drive over a larger manhole, expansion joint, or even the turtles in the road, but then it goes away as i try to figure it out.
It does change tone with speed so it must be on the wheel somewhere and when i slow it usually goes away, or if i hit another bump it goes away. It also is not always the same, some times it is louder some times softer.
Then new years i was headed home about 3am and it was very persistant, so i took advantage of the empty highway and tried to recreate it then hang out of the truck to listen for it. (glad i didn't just get pulled over) but i am almost positive it is drivers front wheel now, but again looking around under there and pulling on the calipers and shocks nothing appears out of place or able to rub the wheel.
The only info i have seen about this noise on the form was someone suggesting that the bearings were going out in the hub or those needle bearings in the whole wheel which was already on my list of PM. My only thought though was these other people said it was consistant noise, mine is intermittent when i hit a bump. Again this is a new truck, i have only engaged 4wd twice to test and once for about 1 min to get out of some wet grass and it worked, i have not even broken open the lug nuts yet, so it really could be anything.
2000 Ford F350 7.3 SRW all stock right now.
