Frame Plug Info

[bobbo929]

I applied Woolwax inside the frame rails and, like so many Toyota truck owners before me, I snapped almost all of the plastic frame plugs that I removed.

I had a heck of a time trying to find part numbers for these plugs on the Lexus website, so I thought I might share this info with anyone else that might have had the same problem. I've owned Toyota trucks for nearly 30 years and finding Toyota part numbers has always been far harder than it should be. I'm still on the fence as to whether or not I actually need to replace the plugs, but I wanted to at least see how expensive they were.

All of my plugs had a label stamped on them, but I could find no relationship between this label and the actual part number.
Plug "A0" - 90950-01A50
Plug "4" - 90950-01987
Plug "7" - 90950-01991
Plug "H" - 90950-01A38
Plug "P" - 90950-01A39
Plug "X" - 90950-01A40

The images in this link are somewhat unique for these plastic plugs in that they show the friggin' part numbers in the diagrams.

I hope this helps someone!

Thanks for posting - this is a huge assist. I had no idea what frame plugs were - but have heard of applying woolwax - so this helps!

As a side note, some of these parts are shared with Toyota-branded vehicles on the same TNGA platform. Playing around with what appears to be the same retailer (not to call out any specific website, but for example, going to lexus.store.retailer.X rather than toyota.store.retailer.X), the same parts are 10-20% more on the Lexus side of the site. Since some of these plugs are only used on the GX, I had to purchase from the Lexus subdomain. Splitting my order didn't make sense since I would need to pay twice for shipping.

Not a big deal in this case, since these were only a couple bucks a piece, but something to keep in mind if I ever need a more expensive part - always check the Toyota store first!

Thanks for this. I just sprayed my Tundra and GX. The Tundra I was satisfied with only pulling one plug. The GX seems like I'm going to have to pull a few on each side to get the rear done properly.

Super helpful, thanks for sharing this! I snapped a few of mine too and couldn’t find part numbers anywhere. Glad you posted this.

I'm curious as to what spray system you used to apply the Woolwax?

I'm curious as to what spray system you used to apply the Woolwax?

As a note, my GX came with a coating of some sort already applied inside the frame rails. I have no idea for sure what it is, but it looks and feels like lanolin. I felt a bit better knowing that it comes with protection from the factory (and I may not have needed to snap a dozen of these frame plugs).

Anyways, I used the Woolwax Pro kit that you can get as a package with a bulk container. Came with the sprayer body, a regular nozzle, 2 quart bottles, and 2 extended nozzles. It was a good deal and everything worked great, with exception of the extensions. The tubes on the extensions are just press-fit onto the fitting that screws into the output of the sprayer. You sort of have to horse the extension into the frame rails at least a little and my extension with the 360 head came off the fitting almost immediately. If you happen to have a small hose clamp sitting around, this is easily fixed, but I don't think I should have needed to stop and make this repair 2 minutes in.

While I'm at it, I might as well mention a bit more about my experience. I sprayed at 90 psi outdoors - perfect day, about 70F with no wind. I prepped my woolwax by warming the containers in a bucket of hot water and it sprayed absolutely perfectly.

I made a drop curtain around the entire base of the car from some plastic sheeting I had lying around, in the hopes that it would keep the mess to a minimum. While that worked fine for the undercarriage, I had to remove the sheeting in order to spray the parts that were best accessed from inside the wheel wells. I thought I was super careful and took my time, but I ended up getting at least some overspray nearly everywhere on the car, all the way to the roofline. Thankfully, at least freshly applied Woolwax comes off quite easily using just the regular pressure washer at the local U-Clean manual car wash.

Next time I'm applying this stuff, I just going to have at it with the sprayer, applying liberally and not worry at all about overspray. After I'm done, I'll just wash it since apparently no matter how careful I am, I'll need to do that anyways.
