Odd rattle on driver's side - can't tell where it's from.

[mcnuggs]

I finally found the source of my rattle- it’s the hood prop… when it’s secured under the hood, the free end doesn’t move, but the pivoting end rattles a ton within its socket. I used a ranger band to tie it up and it’s gone! Feel like there are a TON of different rattling noises in these trucks, unfortunately the solution does not appear to be one size fits all

Never heard my hood prop rattle. But after installing hood struts, I also noticed the prop end was not snug in the holder. I firmed it up by wedging the end of a plastic tie wrap into the gap.

Good news. I think I found the root-cause of the issue. It's the 'plastic/foam' acoustic shield that sits on top of the firewall.

I was tapping around everywhere in the engine bay and the rattle was awful when I hit it. Looked close and many washer nuts missing (I at least found 3 but there might be even more). Either Toyota forgot to put them on or they fall out over time.

I then moved some washers around to see if it can make the noise go away and then took it for a test drive. Rattle was gone!

To make it permanent I need to find either the plastic or metal washer nuts from Toyota or something from the Home Depot. The plastic one are crap imho since they come loose over time.

My question (see my pictures below), does someone know the stud size/pitch/thread so I can find a fitting replacement? The foam shield appears to use a mix out of these white and black studs which might have different sizes.

Hope this helps someone else as well.

Is there a plastic clip or washer nut which should go on top of the yellow base? Because there is nothing on mine either.

For those of us whose driver and passenger side windows rattle when down a couple of inches, and/or all the way down, let's file enough complaints with the NHTSA to get Toyota to issue a TSB. It's free, and only takes a minute or so:

Link to NHTSA Vehicle Safety Report Form: https://www.nhtsa.gov/report-a-safety-problem

I have taken my SR5 in to the dealer three times, and even had it diagnosed by a Master Technician. They heard the rattle, but told me it was "normal" based on looking at other 4Runners that were on the lot. I called Toyota Brand Engagement (800-331-4331), and although they were willing to listen, they are the ones who directed me to the NHTSA, telling me that if enough complaints are registered, they will issue a TSB.

So, how many complaints can we get? 30? 50? 100? 200? Let's see if we can make it happen! Because I am ready to take my door apart and start "fixing" it myself....

WallaceMI, you're the best! I had a really annoying noise that I thought was under the center console. I spent days looking for it but never found where it was coming from. I saw your post and when I checked, I was also missing a nut. After putting a nut in that spot, I tested it for 3 days and the noise was indeed gone. I am so happy. Thank you so much for your help!

Glad you guys have figured it out! I haven’t noticed any ticking noises in my car, but out of curiosity, I took a look under my hood. I also seem to be missing a nut (more on the passengers side than the drivers side), but at least there’s no noise. Well, if I do start hearing something, this will be the first place I look

That’s not the issue with my SR5; I put a nut on it, but I can still hear some knocking in the dashboard.

Hey Everyone,

OP here, I know it's been a long time but following up here in case useful to anyone else.

To cut a long story short, I just wasn't happy with the fit and finish in the car, but probably my own fault for buying a first model year. The dealer had my car for a week or two and was unable to find a fix for the rattle. Eventually I got annoyed enough to take some drastic action and swapped the car for a Lexus GX550.

Wouldn't you know, at about 18000 miles the EXACT same rattle showed up. However this time the dealer was able to resolve and it turned out to be the heads up display housing. Luckily the tech working on the car had seen the same issue on other cars by this point and was able to fix it pretty quickly.

Anyway, hope this helps for anyone who ends up with the same issue.

fwiw

SR5 here, zero rattles. bone stock, none of my crap in it, zero rattles

with all my crap in it, still no rattles

and believe it or not, Toyota doesn't want these to rattle. they devote
a huge budget to eliminating rattles and creaks. so if you got rattles
and absolutely none of your stuff is in the vehicle and something
rattles...push dealer for resolution
