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

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....
