5-10???? I've got 2 bags of decorative rocks (est. 40lbs. ea) over each tire in the rear and it helped a little, but the bounce due to harmonics is still there. I have been told to let air out of the tire atleast 10-15psi.....but i will try the over- inflate and see what happens.
Never felt it in my 08 DC... until I hit concrete freeways in Salt Lake City. Wow, did I feel sheepish. It was just a few short miles, but man if I had to do that every day for long stretches, the truck would be gone. It sucked.
mine doesnt. but if i drove on bad roads it might. so....sounds like a road issue again as stated over and over and not really a truck issue. but oh well. u guys keep thinking what u want.
I wish it was 5-10 lbs. I had a shurtrax with 300-400 lbs of water and it still had the problem. Not as bad but still there. I have since replaced the rear leafs and shocks with better results. Now the bounce has reduced to 50% of what it was. The ride is 70-80% better than stock. I still get the shakes but they disipate much faster. Toyota has really dropped the ball on this one. I am sure there are some that will say this is a truck and it is made to work but I have never had a truck do this as much or as frequent as the tundra. Some one will find a fix but 5-10 lbs jsut isn't going to touch the tundra.

I though it was all in their heads too, until I drove on a white concrete freeway. That's the only place you'll get the harmonic bed bounce, something to do with the way concrete doesn't flex or absorb shock like blacktop or asphalt.
I was just as skeptical as the rest of you until it actually happened to me. Sure enough, you get this truck on concrete, and the thing starts to get that bounce.

Same here, I used to doubt all the bed bounce complaints too, until I drove up north last month and nearly threw up my lunch somewhere in Kentucky from the concrete freeways. Harmonic my butt..... you can look in the mirror and see that bed hopping up and down all over the place. I dont buy that its the roads, my last two trucks didnt do this, and they drove the same roads.
5-10 lbs. in the bed to fix this....... what a joke. I think the guys at the test facility were screwing with him.
I had it everyday really bad when I lived in Vegas I just put everything I own in the back of the Tundra (And a moving truck) took a short drive to Florida and now now it doesn't happen.
SO CURE FOUND

my 01 Dodge heavy duty was very bad on just about any road, had to Carry sand bags. My 04 3500 4x4 dually rides rough when empty. My reg cab long bed Tundra rides great.
I have read so many posts on this subject and yet to have experianced myself, and I live in KY where I drive concrete interstates at all speeds and have yet to feel anything different than my 4runner or my old tacoma, so what is the deal, The only thing I notice is if I hit a major hole in the road the bed will bounce a little, but its a bed and is not connected to the cab so it will give some, but did I get lucky and get one that does not have the bed bounce?

Apparently some of us have them. I have actually tried to get mine to bed bounce by driving washboard concrete roads with no results. The SoCal guys say it isn't the same here, but I fail to see the difference.

The bed bounce phenomenon happens on concrete freeways. Concrete freeways were built in "slabs". Each slab suffers from differential settlement from the excess weight of traveling vehiceles. I beleive the length of the concrete slab along with the wheelbase of our trucks and most importantly the spring rate of our leafs all bounce in a harmonic or resonant motion. I do not know why Southern California freeways suffer more than other states. My only explanation is that the excessive vehicles or more traffic than other states. So you other guys that have not experienced this in other states, I gaurantee that if you drove to SoCal over a bumpy section of concrete frwy, your truck would bounce.
This problem can be fixed if the concrete freeway is ground down to create a smooth surface again. The 10 freeway between the 15 and 215 used to cause really bad bed bounce. Now, about 85% has been ground down and it's as smooth as can be until you hit the one section that wasn't ground. We should all complain to our state and make then grind the freeways.
By the way, all light trucks suffer from this. I have driven on the bumpy section on the 10 frwy in a 2008 F150, 2005 Silverado 2500, 2006 & 2008 Dodge Ram and of course my 2008 Tundra and all suffered from bed bounce. My Tundra and the Silverado was the worse, but all could be categorized as severe bounce. Just my 2 cents.
