Strange Noise
My truck started making a rattling sound (as if the something was loose and rattling due to vibrations)
It happens when I first crank up the truck and when I make right turns. Also right after I crank the truck if I mash on the brakes it changes the sound a bit.
I had a mechanic look at it but he couldn't find any thing.
Got any ideas?

maybe one of the dust shields around the brake caliper is just close enough??? when you push the brake it may push just hard enough and move the rotor to change the tone of it.... just a thought....

It is definitely not the idler pulleys or the belt... I took the belt off and cranked the truck and the noise was still there. The only pulley spinning was the fly wheel.
The brakes and bearings were completely redone a few weeks ago.
The noise seems to have gotten a little worse, and is definitely coming from the passenger side.
What could be vibrating on the right side, that stops at higher RPM's, gets worse on right hand turns, and dissapears at idle after putting the truck in gear and driving?
Problems with the hubs... or suspension? could these be culprits?

Jack up the front axle so both wheels are off the ground. Spin the tire and if the axle shaft is moving, that is your culprit, your hub is sticking. Might need to get a replacement or change out to full manual hubs.

I jacked up the front end and the hubs checked out ok. I took a closer look at the brakes and rotors on both sides everything is ok.
The noise doesn't change with speed or engine rpms, nor does the truck pull when i brake (brand new brakes). It could be the exhaust but it sounds too solid.
Bleet, where are these bolts youre talkin about?

I think I may have just found the cause of the sound.
The one of the exhaust links broke and the DP was rubbing on the frame... I engineered somethin up to stop the rubbin and no more noise.
Hopefully this is permanent.
Thanks for all the help!
