8 UR HMI Posted October 21, 2010 Report Share Posted October 21, 2010 ok heres the sound ive been trying to figure out. its not motor knock cause it doesnt do it all the time and it is ESPECIALLY loud when i run over bumps. it started the day i got my truck back from the driverside front hub assem. but the sound, sounds like its coming from the dash but i pulled the radio and listened and its hidden. i cant figure it out. my exhaust isnt loose, theres no bolts loose, i just cant figure it out. any ideas? im gonna take it back to the place that did all the work since my alignment is off (they aligned it and the truck shakes at 62mph. ) so im gonna make them diagnose the problem if i cant figure it out.

Cramer Posted October 21, 2010 Report Share Posted October 21, 2010 I wonder if it's one of the HVAC actuator doors flopping around in there. I have heard of them breaking, but I don't know what they sound like when they are broken. Try turning on your heat or A/C and see if it changes.

Oscar8415 Posted October 21, 2010 Report Share Posted October 21, 2010 Check the A/C fan blower Try turning off your A/C and see if it changes Quote Link to comment Share on other sites More sharing options...
ThatTallCanadian Posted October 21, 2010 Report Share Posted October 21, 2010 It sort of sounds like a bolt rattling inside a hollow compartment... Maybe they dropped a bolt or something into your air vents or w/e? Sounds dumb I know. Quote Link to comment Share on other sites More sharing options...
70chevy03ss Posted October 21, 2010 Report Share Posted October 21, 2010 Its really easy to remove the top of the dash. Maybe try that Quote Link to comment Share on other sites More sharing options...

Shaking at 60-65 mph is tires out of balance. The noise you are hearing is something loose/busted behind the dash; some very small detail can cause a major racket like that, my GF's '06 mustang had a A-pillar cover vibrating against the dash and it was that loud, it took several weeks until I tracked down the culprit. When it's making the noise, lightly run your hand over parts of the dash and see if you can feel vibration; try opening the glovebox door all the way and maybe the noise is coming from the climate control ducting??

BlueAKSSS Posted October 21, 2010 Report Share Posted October 21, 2010 I would pull the top of the dash off since it's really easy, and then listen for the noise again, maybe easier to track down. Quote Link to comment Share on other sites More sharing options...
stg313 Posted October 22, 2010 Report Share Posted October 22, 2010 I can tell you that its not the motor that controls the HVAC doors........ mine is broken and sounds nothing like that. Quote Link to comment Share on other sites More sharing options...
slowfive0 Posted October 22, 2010 Report Share Posted October 22, 2010 Possibly the steering column slip joint. Very common on these trucks...... Also, noises can be very deceiving. I had one that sounded like it was in the a-pillar...I tore the dash apart trying to isolate it. Turned out to be a metal tag on the radiator support that was buzzing at hwy speeds! good luck Quote Link to comment Share on other sites More sharing options...

Turned out to be a metal tag on the radiator support that was buzzing at hwy speeds! good luck i just thought of that. it does it at idle, and only in gear...... but i have noticed it to be louder when i turn but it sounds like the center of the truck rather than the steering slip joint..... idk. im going back to the shop tomorrow that did the work after changing tires so they will have to realign it since its not right to begin with Quote Link to comment Share on other sites More sharing options...
8 UR HMI Posted October 24, 2010 Author Report Share Posted October 24, 2010 now its doing it at idle in park, i can put my ear against the winshield and hear it, but when i put my head against the hood (checking for it to be the motor) i cant hear it. i know its not a screw or bolt losse because it doesnt "rattle" like one.
