lol well I sure was not saying 100,00 trucks in anyway ... it seems you assume that every truck has this issue and thats not the case by any means ... just some have it and it's not only on bad roads as you state.
Like I said they recalled a few driveshafts so that proves they arent using the same exact correct part in every truck ... things will slip through.
Oh and by the way I love Tundra's this is not a smear campaign its just food for thought to get to the bottom of this issue and I think an easily correctable one once the right ingrediants are in place.
Bearings, gears and axleshafts are required to have very tight tolerances, unless toyota went with some chinese bearings, and changed from their gear cutter. I will still bet that it has nothing to do with the vibration people (myself included) are feeling.
Watch a Silverado, F250/250... etc. go down the same highway, their frame flexes at the bed/cab also....
I did not say the spare tire trick would not work in any way
Again think about why the spare tire would work, it quells the harmonics!!!!!!!!!
If anyone is being negative its you
Slow down there Chief... look at who's post I was quoting... not yours.
You've been making suggestions of other things that you think could be causing this problem.. Even if I don't agree with your suggestions, at least they're productive, and better than somebody just saying Bed Bounce doesn't exist because I don't have it.
My thinking however is that their are 2 issues, one of a harmonic one and one of where some Cali people are experiencing on bad roads, they may have something in common but not quite the exact same issue.
The only time I ever feel the bed bounce is on slab freeways here in SoCal. Everywhere else it is fine. It has to just be that it is that stiff. Especially considering I have a RCSB 2wd and the same leafs that would be on a Crewmax 4x4.
The truck handles like a dream! But even when I climb onto the tailgate the truck doesn't even drop down a 1/4inch! When I jump up and down it might compress 1/2inch if i'm lucky. I only way 160lbs but still this thing is HD to the max. When I had a lil over 1000lbs in the bed it didn't even sag the rear end at all it was still way up there.
The tonneau helped tons though! Especially with off the line traction, traction around corners and traction in the rain.
I'll be installing the Ground Force Lowering kit on my tundra at the beginning of January and i'll let you know how it rides after that. It comes with all new front coils and rear leafs.

I’m sure anyone with an engineering background would understand the bed bounce issue. All trucks have it under certain conditions. Just because you don’t recognize it, or experience it doesn’t mean it isn’t there. Nothing is perfect for every usage so all is a compromise. Under certain conditions, this condition is annoying enough to warrant trying to come up with a remedy for these people.
The cause has to do with the shocks, springs, frame and their geometry to one another. Regardless, it makes since that using the tire as a counter balance to dampen the oscillations may work. An air ride suspension with variable rate shocks would be a great alternative, however unrealistic in the price range that most trucks fall into. I have heard that the new Dodge ½ ton may be coming up with a totally new rear drive train, suspension and geometry. From what I have read, it may be a major break through and has the potential to deal with many of these issues. First thing, is that it will not use any leaf springs.

I drove my '08 Tundra back from South Carolina to British Columbia 3300 miles and my only encounter with bed-bounce was on I-25 north of Denver to the Wyoming State Line. I watched the bed bounce through my rearview mirrors. IMO, the cause of bed bounce in Tundras is not a Toyota design issue, but due to some freeways badly in need of repair. The freeway wasn't designed or built that way.... just allowed to deteriate to it's present poor condition.
A great example is the 710 and 91 freeways. You locals know what I'm talking about. So Basically what I'm getting at here is, guys from Texas and Colorado shouldn't be flipping out about never feeling the bed bounce, like I shouldn't flip out because my truck doesn't drive well in the snow or my de-icer doesn't work when there heavy ice on my mirrors. What the hell would I know about snow and Ice conditions?
Amen.... or try driving the 101 from Sherman Oaks to Ventura - thought my teeth were going to fall out.
And personally, I think "bed bounce" is a misnomer -- the ENTIRE TRUCK bounces up and down. Stuff falls of the seats, drinks spill out of the top of the can and the center console pops open because everything is shaking so bad in the cab on these stretches of the freeway.
I'm disappointed that some people can't acknowledge and respect this problem -- the results of the bed bounce survey we did show that it's a significant and real problem independent of geography, wheel base, cab type, TRD package, etc. If you feel like being critical of the people having this issue, maybe you should keep your thoughts to yourself.
ANYWAYS...
So far it looks like only a couple of you have tried this out. I noticed that one of you used foam that was 1" thick, and that one of you didn't specify.
When we were putting this article together, we tried to determine what kind of foam was being used and we haven't figured it out yet. However, this is a difference between "closed cell" foam and other types of foam you'll find at the hardware store, etc. We'll try and find a cheaper source of foam and buy it in bulk if this cure works like we hope it will.
Also, our reader that came up with the fix suggested tweaking the tightness of the spare tire to get the best results.
We've got a couple of volunteers waiting for the pad to arrive at their door. Once it gets there they'll install it and let us know how it went for them.

No it showed that you got only 102 people to agree to whine about it.
You didn't even provide a section for all the people that don't want to complain to be surveyed.
I stand by the fact...THIS IS A NON ISSUE AND TOYOTA WILL DO NOTHING ABOUT IT.
Petition your state and local governments to fix your roads, you'll get more than 102 people to agree with you and they will drive every make and model vehicle.
But for you 102 people, sorry you feel something is wrong with your trucks, hope you figure something out.
Majority is going to win on this issue, and the complaints are the minority...FACT

We'll add you to the "bed bounce denier" group. Why do you feel compelled to criticize and deny what others are experiencing? And how do you know you're in the majority based on an Internet forum? I would argue only Toyota knows the answer and they're telling people a fix is in progress.
This is just off the top of my head I got to thinking of how a fluid dampener worked and this is what I came up with.
How about some type of high-density rubber tube (inner tire tube) filled with fluid silicone based ECT. That might work to cancel out the oscillation

Sounds like a good idea, I was just thinking anyone remember those stretch toys you could stretch their arms and legs like a mile (toy from the 70's) ... they made the "Hulk" and a bunch of others ... well mine busted open when I was a kid and there was some kind of very heavy Red Gel inside them ... one thing I remember was punching the one I had and that thing would absorb energy like nobodies business ... something with that stuff in it, between the tire and frame would prolly work fantastic.
I am in no was saying using a "Hulk" but I pictured that thing between the tire and the frame and it did seem sort of funny lol
