You're a smart guy, sad your input on this forum doesn't reflect that.
I'm going over the speed bumps slow, almost at a crawl. Yes, I drive my truck fast but not in grocery store parking lots. I will address my issue with my dealership next week when I go in for the first service.
Any other input, smart guy? So, which dealership do you work for?
I don't think there was a need for that. I was just making my previous point again that the people that are adding to this internet problem, haven't gone and had things checked out.
What dealership do I work for? HAHA That would be the day man.
Anyways, are you sure that its not the tailgate making a noise? Mine does that on some rough roads. At least it did until I installed the tonneau and there is more pressure on it now. I havent heard the noise again.
here we go again.....it's a truck boyz, if you wanted a smooth ride you sould have bought a camry.....now pull your panties up, get a 6pak of bud pounda's and go rip on your tundra.
This is a Tundra problem, not a TRUCK problem.
I don't know how many times it needs to be stated that this is a unique problem to the Tundra. Chevy doesn't do it, Dodge doesn't do it (from my experience, and talking to people with a similar commute.)
Calling this simply a truck problem, is like calling the clock issue a truck problem. 'You girls should have bought a cadillac if you wanted a clock that kept time!'
The Tundra rides far better than any truck I've driven, and those trucks DO NOT have this issue.
The bed bounce video gives us an issue to hang the problem on. It does not create complaining about the problem. If the video never existed, we'd have just as many complaints about it, but they would read:
"My truck is bouncing like a rubber ball when I drive on bumps, wtf!"
I agree with Smilodon. I just picked up my 5.7 Limited CM 4x4 last night (for all the doubters, give me a number I will put on the windshield …) in Calgary Canada. I was driving down Deerfoot (a concrete freeway in town) that they are repaving; doing about 100 km/h (about 60 mph) and no bounce. The road is bumpy, granted, nothing like the 50 speed bumps in the ford video; but if you are driving on roads like that reqularily, buy a tank! I think the video, like the camshaft, got people excited; 2 weeks from now this will be a distant memory. There were very few complaints, if any, about bed bounce before the video.
Enjoy your ride, if you don’t own, get one. If you can’t afford one, steal one (not mine). They are luxury sleds with the power to do what you need too and the flex to keep the wheels on the road and your head on your shoulders.
I am totally not concerned about the video. That phenomenon in the video will only occur when the excitation force's (in this case road bumps) frequency (based on distance between bumps and speed of vehicle) reaches the natural frequency of the bed to frame "rubber attach point" and/or rear suspension natural frequency. It's known as resonance and under this condition the suspension can actually begin to further excite the bed bounce issue. Additionally, I think the bed bounce is further exagerated because there appears to be a rubber damping spacer (saw a pic in an older post) in between the bed and the frame at the attach points. Sure the frame bends under torsion as Toyota designed it to, but I think the rubber attach points are allowing the bed to continue to oscillate after the frame returns to its equilibrium condition. Ford chose their "test" speed such that this particular condition occurred with the Tundra. All they had to do was watch the bed as they varied the Tundra speed along this track and then choose the speed that had the most dramatic effect on the bed. My guess is that they were probably trying to find the speed condition where the Tundra left the road like the Chevy, but when it didn't (due to good suspension and frame design) they settled on "mocking" the bed bounce issue. A little slower or faster and the violent bouncing would have significantly decreased. At least the Tundra stayed on the road. The Chevy bounced all over the place. Today during lunch I noticed a 07 silverado has the bed rigidly attached to the frame, no rubber damping like Tundra. There exists a speed at which the shorter wheelbase Ford will also experience this and the Tundra would not.
As far as the talk about real world experiences on bumpy roads (which concerns me the most), I still think it has to do with the rubber dampers in between the bed and frame allowing too much oscillation. I bet if you replaced them with a more stiff rubber spacer it would decrease this continued bouncing after a bump is hit. Even tightening the current bolt that I suppose runs through the rubber spacer would compress the rubber and also probably improve the ride.
Just thought I would share my 2 cents as I have been writing about spacecraft fuel slosh and natural frequencies all morning...
I guess I should add that based on the limited information that I have about the design of the trucks mentioned above and as to the nature of the problems these guys are experiencing on rough highways, this "speculation" could be completely wrong!
The problem I'm experiencing is not 'perceived' nor is my issue a 'worry wart' issue after watching the ford bashing toyota video. The problem I'm experiencing is real, nothing I've experienced with past trucks. For those of you out there blindly defending Toyota...try going over a speed bump with your windows down. I'm shocked if you're not experiencing the same symptoms as I and many others on this forum. There is a distinct thud sound from the bed and visable movement. I realize that many people on this forum are dealership employees who represent Toyota products but enough is enough. Most people are citing real world examples of issues they're experiencing with their vehicles. Accepting the feedback and working together to resolve the problem would require far less energy than blindly defending Toyota. And no, I'm not a troll.
I explained perceived in my post, in that I assume that I have the same truck as you do, the bed probably "bounces" but I don't perceive it as a problem, for whatever reason.
I also said some are using the video as an example of the "problem", even though the video is a rigged manufacturer's shill piece. If that doesn't apply to you, fine.
As far as "accepting feedback and working together", you are doing neither. Accusing me (and most on this board) of being a dealership employee plant and "blindly defending Toyota" is pathetic, and shows your inability to accept any feedback that doesn't match your own gripes.
And "working together to resolve the problem"? Again, you apparently expect everyone to agree with you and somehow leverage this "power" to do what? I'm sorry if everyone doesn't see things your way, thus spoiling your concept of "working together".

Believe what you say but not an entirely accurate statement that this is not a truck problem. Posted this in another thread but in edmunds review of 2007 GMC Denali (which is a great truck also) they say about the ride:
...This is particularly apparent on California's concrete freeways where the rear end can bounce along with the undulations to produce an agonizing harmonic that makes it impossible to have a conversation inside the cab....

I think these are 2 separate issues? I have no bed bouncing issues, but I get the harmonic truck shake over California's crappy freeways...
How bout this idea. Ford put out their video, does anyone have a little extra time out there to video what they are experiencing. Maybe a buddy filming along side while going over some terrain that is producing the dreaded bounce or someone videoing the bed out the back window!?

Well there's a novel idea.

I'll try to borrow the video camera from work next week and try to film this in my truck. Lots of interesting comments in this thread, but you either experience or you don't... simple as that. For those of you that have no problems, don't disregard our comments about the bed bounce because it is quite real for some of us. If I didn't drive the highway I take to work, I wouldn't have experienced it either. The Ford video had nothing to do with me noticing it either... I experienced it on the drive home from the dealership a month ago, I just watched the video two days ago. It was enough to think I had a problem with my Tundra on the drive home and thought about taking in to the dealer for them to check out. NO vehicle I have ever drove has been this bad, but my experience has been limited to Chevy Silverado's, Ford F-150's and the previous Toyota Tundra. This was not a problem in the previous Tundra over the same stretch of highway. Am I demanding a fix for this... no. Although it would be great if Toyota addressed this and came out with a fix... but I don't expect them to. Added weight does seem to help. A full tank of gas, and it does improve slightly. Slowing down from 70-75 to 55-60 helps keep control of the vehicle. Would have this changed my mind about buying a Tundra if I had known about it before. Probably not. On smooth road, it drives like a dream! Now if I can get the state to just improve all the roads, my problem will be solved!!!

I agree... it's funny how the more things change, the more things stay the same... if any of you were here 5-6 years ago, you'd remember the constant brake vibration threads. People were screaming at those having problems, "You're too hard on your brakes! Slow down!" "I don't have any problems, you shouldn't either!" "You don't even own a Tundra, you're a Ford Troll." Same crap. Years later, TSB for the brakes.

I'll go even further, even on rougher roads, it's just awesome. There's just 0.0001% of the roads out there where there's something wrong.
As for the video, no one should trust anything any company puts out, be it Ford, Chevy, or even Toyota. It's marketing people, they'll figure out a situation where they prevail, and then make that the most important issue of the day.

I've got a video, it's of poor quality, and at night, but it effectively shows off what I'm experiencing, which is not bed bounce. I tried uploading it to my photos but it just crapped out on me for some reason. Youtube is down too right now... going to keep trying to get it online...
*edit* I'll upload tomorrow... TundraSolutions is acting finicky, won't even let me attach it to a post...
I have owned the following trucks over the last 10 years.
97 F150 reg cab
99 Mazda Extra Cab
2001 Chevy Silverado ext cab
2004 F150 Crew 4wd lariat
Now 07 Tundra SR5 Dbl Cab 6.5 bed
I have driven the same SF Bay area roads for the last 10 years at an average of 50k per year. Gents, there is a shaking in the bed/cab like I have never seen or felt in any of the trucks above. Most notibly on highways 24/80/101. It is bad enough to where my voice is rattling when I speak. Other then these stretches of misery, this Tundra feels and drives much better then any of my former trucks. I truly dig it. But there is anissue. cheers
I agree, there is bed bounce over certain terrains at certain speeds. I drive 29 miles each way to work, I take my Tundra once or twice a week and there is a quarter to 1/2 mile stretch of I 84 at Orchard in both the east and west bound (for those who know Boise, you know where) I get some bounce at 70-75 but I can see it is the concrete expansion joints. My wifes Nissan Armada soaks it up (all independent supsenion helps) but you do get the duddaduddadudda till your out of it. I have driven my truck down dirt roads that are like a wash board, and it bounced I sped up bounce went away, slowed down bounce came back, slowed down a little more bounce went away. We drive an 06 4x4 long box f-150 at work, it bounces the whole truck, its noisy, horrible breaks. But to each there own, I drove the GMT-900 (new GMC) in 1/2 and 3/4 ton (1/2 ton 6 times 3/4 3 times), they felt soft (no bounce) and did not give a positive feel, and I drove an 07 Titan Crew cab off road package (twice) it bounced as well till you adjusted the speed, before I decide on the tundra. I really wanted to buy the GMC, but it just was not there.
