One of our readers, Matthew Davis, came up with a possible solution for the Tundra's bed bounce.
Basically, he took a piece of foam rubber and placed it between the back half of the spare tire and the frame. Then he tightened the spare back into place and effectively the spare became a damper.
Here's a basic picture:
You can see that it's not much foam in their, but he says it made a big difference on his truck.
The full explanation on more photos are on TundraHeadquarters.com
I complained about this problem to my dealer and the best advice that the dumb salesman gave me was to "keep sandbags or something heavy in the back...". yea thats real smart!
Unfortunately, adding weight hasn't helped me, and I don't really feel like messing with foam and my spare tire.
Someone had a great hypothesis that Toyota could have missed this problem during their testing if they didn't have spare tires in their test mules. The plot thickens...
I feel you peoples frustration, but all the guy is trying to do is help you out. If Toyota come up with a cure for your so called bed bounce (mine does not have the bed bounce issue) it mite be the same thing he has done. Just maybe the best thing to do is just keep the things that help "your" problems to his self. If this bed bounce thing pisses you off so bad you cant take a little advice from someone maybe you should sale it and get yourself a big 3 pile. O buy the way. I could care less if they ever come up with cure for it. Because I don't have it.
Maybe the OP should have gotten a patent as Toyota may end up using this idea!
As for me, I'm going to go to Home Depot and get a garden knee pad and try it.
It freaks me out when it starts to shake -- at certain speeds on certain roads, that don't even have to be that bad, it will really start to shake like crazy. Other than that, it has a fantastic ride for a big truck.
I'm gonna try this out tonight. Mine is horrible. I'll let you guys know how it goes.

Great info. Certainly worth a try for the price. Heck I'll try it and I don't seem to have bad bed bounce but if it contributes to a better ride, why not. Those that try it, keep us posted.
I'm gonna try this also, but I'll tie a rope around the spare tire to the chassis just in case the cable assembly brakes, the tire won't fall off the truck and cause an accident.
Awesome! I'm glad to hear so many people are going to give it a shot...let me know how it goes either on TundraHQ or here in this thread and I'll post your experiences on the TundraHQ blog.
I just cut some pieces out of some foam flooring like they use in weight rooms and I'm about to take it for a drive. I don't know if this is related to the "harmonic frequency" issue but I've noticed that when I drive over speed bumps at 10 mph or higher the back end reverberates for a few seconds after the back wheels have cleared the bump so I'll try the speed bump test also.
that has nothing to do with bed bounce, that foam rubber (snake oil) does not apply here, since the spare tire is attached to the bed, come on guys let's be real, any bed is going to bounce some.
