8+ hrs wasted on strange noise

So, I was installing rock lights the other night and decided to wire some under the hood... So I get in the truck to go to work the next day and there is a very annoying rattle coming from the dash. I figured it was the wires flopping in the wind or something. It seemed to kick in around 30mph.

So I come home and make adjustments trying to make sure the wires cannot move.. Go for a few rides and the rattle continues. I start to look elsewhere thinking maybe it could be something in the suspension (maybe A CV axle....). The noise seems to come from the driver foot well area. I finally give up and go to bed.

I get my gopro this morning and go for a few drives... The noise seems to not be heard outside.. Finally I rip out all the lights under the hood since that was the only new variable. AND the Noise still present, maybe worse.

At this point I'm getting frustrated and start tearing apart the dash looking for something loose. I i put my phone up in the dash and the noise seems to be coming from there, but I can't find the source and it is impossible to get under there while going 30+mph down the road. I keep trying to brainstorm troubleshooting ideas...

I keep stopping myself, thinking this has to be something simple, Roof rack.... I inspect the entire vehicle from top to bottom and even fix a few minor squeaks...but the annoying rattle is still very present. I've burned about 1/4 tank at this point.

Finally, when I was just about to throw in the towel for the day (this was a solid 8hrs into it, I do another inspection out in the sunlight. And then I see it. One of those little plastic pins that holds the rubber mud curtain in place (near the driver UCA) had popped out and was allowing the curtain to hang loose. That stupid SOB was flopping in the wind and resonating through the frame as the pin hit it. It was most likely loose from when I changed the UCAs a few weeks back. :frusty: Even though I had re-installed it, it had made its way loose (since they are not that secure once pulled).

Oh well, time to go put the dash back together ;-)

Lesson learned, bend the little plastic hooks back out on re-install so they will stay in place and not cause a mystery noise....

Ah man how annoying.

I was frankly a bit surprised at the amount of plastic push pins holding things together now. I swear there are easy 10x more than a 3rd gen. I popped off my left rear fender flare and broke a blue and an orange retention clip...and I was careful.

Hit up the Chinese connection on fleabay for a multitude of plastic "same" quality retention components at a 20th the price, fast shipping too. Toyota wanted a $1.32 a piece for the push pins that keep the plastic cowling on over the radiator, I got 20 for $5 and change shipped, compared it to OEM, swear its the same piece, rough orange peel texture and all.

The fender clips are one use only, but yeah these days they use a ton of plastic fasteners. I imagine it makes the vehicle crumple better.
 
LOL yeah I gathered they were single use after I saw the clips. Expensive little buggers.

I pretty sure the ones [MENTION=106176]wfo9[/MENTION] is talking about on the "seals" are supposed to be single use too, aren't they? These: 90467-10186 I think. Man that crap flapping around drives me crazy. Every time I turned left in my old pickup...because I was to stupid/stubborn I guess
 
I've been there. It's always the simple stuff you overlook. It's good to get the blood pressure up every now and then, right? lol
 
Haha, that one drove me crazy for a week once, it is now the first thing I check. I replaced some of the clips with zip ties and the white interior pop fasteners hold much better and can be reused many times.
 
been there too. exact same issue. didn't take me too long to track it down, but it was a head-scratcher for a while there.

there was at least one or two threads on this same subject some time ago and it seems like the driver's side clips are the most common to let go; even folks who haven't un-/re-clipped when doing a lift and/or UCA install. this has happened so often and tricky enough to track down it may be a good candidate for an addition to the FAQ thread?

perhaps a link, kind sir? :hatsoff:
 
My rattles were
- a small fire extinguisher I put in that nook between the second row of seats and the sliding tray, and I forgot about. (For putting out Chrysler fires).
- mag lite in the map pocket or whatever you call it on the first row doors. Turns out its perfectly sized for a two cell Mag lite and not much else.

Just grab the part number from camelback parts factory or other OEM site and search it at the auction site. There are quite a few sellers, the sellers I have bought from are transglobalauto and carbodys. The latter being the cheapest.

While I prefer to stick with OEM parts, aside from upgrades, these stupid plastic disposable parts are just a hinderence.

That exact noise [MENTION=106176]wfo9[/MENTION] mentioned drove me crazy for MONTHS! I would only hear it at high speed on the highway. I was working on the truck with another member on here and he had figured it out on his. We just hot glued that area back together. I think the pin was loose. I know it's probably not the absolute best way to fix this, but if I ever need to get the splash guard off I figure I can just cut the glue or the pin and replace the pin.
 
It's always the simple stupid stuff that can be most difficult to track down.

My pristine 2002 had a rattle (I HATE rattles) somewhere around the drivers back door that I never could track down. If I cracked the window it would not do it so I took the entire door apart, replaced all the window seals, remounted the window motor and regulator basically completely rebuilt the entire door structure, got it all done and on test drive same @$!?ing rattle.

I could have screamed.

I feel your pain. I probably spent 20 hours trying to figure out that rattle and never did. It was like the evaporative system code the truck started throwing 4 years ago. I spent hours checking everything, replaced the fuel cap, etc.. and about every 3 months it would throw the code.

I have not encountered many problems I cannot eventually figure out. This one had me stumped so I finally ended up taking it to the Toyota dealer. They spent 3 hours diagnosing it before they figured out what it was - the plastic charcoal canister above the fuel tank had a hairline crack in it. One of the techs there had seen the same issue one time before.
 
thanks!

and thanks again!

and also: thanks again for the tip on that 64.5mm oil filter wrench. (this was a while back.) it's a perfect fit. no more fussing with the one i got from dealer parts (a pinch too tight). thanks!
:cheers:
