Hey guys, when i was idling today in a parking lot i felt a thump and heard a thud underneath my feet. exhasut leak or what? the rpm gauge didnt move a bit doing this. what could it be. is it serious. what do i need to do to fix it?

also... how do you remove your spare tire
thingy errm wench thingy.? anyone ever do this?

 

The spare tire wrench(rod?) just pops out of its snaps.

D/k about your thump.........get it up on a lift.

dont know about the thump eaither. motor pulls strong. its right under the drivers side floor board. only does it occasionally when i idle. exhaust maybe?

About the tire: i ment the actuall wench and cable that holds the spare up there under the bed (the whole housing). i want to take it off. im having problem with the big plastic tube guide that houses the thing to lower it. once i get that thing off, wont be a problem.

 

Maybe you need to UN-pump up the volume on your radio.

Can the clunks cause this??

 

hehe.my radio wasnt on.

 

check your pcv valve if our trucks have one (Just switched one out on a friends ricer and fixed his rough idle no problem, never done it on my truck though) and plugs, could just be a rough idle.
Also may want to clean the iac valve and check the fuel filter, a rough idle is not neccesarily a bad thing, but it can definately lead to bad things if unatended to.

i need more input. im going in to get a new fuel filter and new plugs in a week or 2. like i said. my rpm needle stays steady and it doesnt look like a rough idle.

 

could be maybe a loose exhaust bolt or something?

 

I have the same thing, has this been resolved???

 

did you just cut your AC on when you heard the noise?

 

More info please, sir! Thank you! Peace!

 

No, I know that noise!

 

NateTrun2,

I could venture a guess that it maybe related to your ABS (Anti Lock Brakes) system. Occasionally, the ABS system will go through a system check which can result in what seems like a thump or thud coming from the floorboard. The ABS Hydraulic Control Unit is located on the driver side frame rail close to the air filter. When it does a diagnositic system check the movement of the hydraulic valves can be transmitted through the frame rail and sound like a thump or thud which is normal. This is only my opinion as you said the sound was very occasional and intermittent.

Good Luck
