Possible Tundra Bed Bounce CURE FOUND

Why do you make it seem like that's a bad thing? Since when did truck manufacturers start trying to achieve more "Truck Like Rides"? Boy wouldn't that make for an interesting commercial.. "The New Tundra with "Truck like RIDE". Maybe they'll make it optional too.. "Can I get this with the 5.7 engine, Backup Camera, Crew Cab and oh yeah.. Truck like Ride!

If I can have a car like ride in my truck then I'd gladly take it as I'd imagine most people if given the choice would as well. Granted that it doesn't' take away from the trucks capabilities. Who wants a bumpy jarring ride anyway?

I'm sure you'll say that in order to get a car like ride that it's mandatory that I give up towing and hauling capabilities, etc. I would disagree with you there.

The new 2009 Dodge Ram with it's Car like Ride will:

Max Payload = 1850 vs Tundra 1755
Tow Capacity = 9100 vs Tundra 8600

They even have a video that addresses Highway Hop. aka Bed Bounce.

Dodge - 2009 Ram 1500 - Capability - Ram vs. Competition

I"m not trying to hate on Tundra.. just pointing out that you don't always have to follow the mindset that great hauling and towing performance means $hitty ride!.

Not at all. But it you want capability, or ride, gotta give it somewhere.

You can disagree, but the more truck capability you need, the more "car" you have to give up. Thats why 3/4 and 1 tons dont ride like Cadillacs

The new 2009 Dodge Ram with it's Car like Ride will:

Max Payload = 1850 vs Tundra 1755
Tow Capacity = 9100 vs Tundra 8600

Or wont.... Those numbers dont quite jive, apparently differently spec'd models. I browsed the Dodge Ram website, this is what they say on their own comparison page:

2009 Ram 1500 Crew 4x4 Short box: Tow = 8450, haul = 1470

2008 Toy Tundra CM 4x4 Shortbox = Tow = 10100, haul = 1515

Attached in the screenshot in case theres any doubt.

So, the car-like ride clearly comes at the expense of capacity. Again, The Ram is aimed at a specific audience - people who want a truck, but do car-like things with it. The Tundra is made to be a truck, and excel at it. The Tundra is the heavy-duty 1/2 ton, some guys here have pulled some exceptional loads. Try that, and do it as well, with a comparably equipped F-150 or new Ram. No thanks!

There's a BIG difference, a lot of us with the bounce just want a smoother ride, doesn't have to be Caddy-like just not teeth rattling is all. I can't even talk on the cell phone on some parts of the freeways because it bounces so much.......som-m-m-m-m-m-me one plea-s-s-s-s-s-s-s-s-se com-m-m-m-m-m-m-m-m-me up-p-p-p-p-p-p-p-p-p-p-p-p with a-a-a-a-a-a-a-a-a fix.

Thats just plain old BS. According to the Toyota factory Rep. that rode in my shake-n-bake bed '07 Crew Max the Triple Flex...I mean Triple Tech frame was designed for ......... the envelope please................RIDE COMFORT.


What was the topic here again?

[MTeator]

I hate riding down the road with the bed bouncing all over and some people pass by in a chevy or ford and point at my bed laughing. And not like I can say anything as I'm being shook to death. I really wish I had known about this before I bought the truck. And whoever some posts back says it's the springs, it's not, it's the frame. I stuck my racecar camera under the truck and you can see the frame flexing. It's really bad if I'm pulling my car trailer empty, it makes it twice as bad. Loaded it's fine, but I don't always have my car back there.

I think Keto likes to argue just for the hell of it. That "somewhere" he lives in Im willing to bet is not in So Ca. If you have never experienced the bed bounce then you dont know what its about. Its easy to say not a big deal if you've never been shaken to death while on certain parts of the freeways. This topic is about trying to find the cure to it, not talk people into thinking its swell.

Same could be said for many here.

I live in Northern CA, we have the same concrete joint type freeway in a couple places, mainly I5. But if thats not good enough, I've been down in LA and SD several times in my Tundra, as well as my previous trucks. I have a 4x4 DC with stock suspension and tires. It is not TRD either. I've never had non truck-like behavior down there or up here. Some call it "bed bounce" - I call it normal large truck behavior. Most of the freeways in LA just plain SUCK.

So, since this topic is "about finding a cure", here a few:

1. Put some weight in the bed.
2. Change your suspension.
3. Put a (5th wheel) cross member in.
4. Buy another kind of truck (or perhaps a minivan?).

Toyota isnt going to change anything, so its up to you. Those are your options. After 26 pages, its become more about whining and b*ing about Toyota or the truck, than it is about finding "a cure".

Since I dissent from the Collective in this topic, I will bow out and leave you to your discussion, unless of course somebody brings me up.

We now return you to your regularly scheduled programming....

I live in So. California (have all my life) and have driven my truck on most of the LA and SD area freeways over the last 18 months. I personally and definitely have never experienced anything resembling what has been described here. For sure there are sections of highway that suck and the ride reflects that (but then again it has in all the other trucks I've owned too). From my experience, I would have to agree with Keto's "normal large truck behavior" comment.

i have experienced bed bounce/hop in 4 previous trucks a 1997 dodge 1500 4x4 ext cab, 1996 chevy 2500hd ext cab 4x2, 1999 ford f-150 4x4 reg cab w/ 8' bed and a 2006 chevy 1500 silverado reg cab 4x2 w/ 8' bed .personally i do believe there is a such thing as bed bounce/hop, yet i do also believe it is a characteristic of trucks. i used to be in the armed forces and used to travel quite a bit. most of the time it occurred on bridges and random sections of interstate that are concrete. so in my experiences its just something i have gotten used to. i have yet to experience it in my tundra, though i don't travel much any more and have just recently purchased this truck.

with the dodge and the ford i was able to somewhat make the bed bounce/hop easier to deal with by install a weather guard pack rat pullout drawer toolbox.

hope this info helps others.

01 Silverado ext cab Z71 4x4 not as smooth as a minivan but okay.

05 Frontier crew cab NISMO 4x4 smooth.

07 Tundra DC TRD 4x4 too bumpy to carry on a conversation.

All of the above on the same SoCal freeways. If I lived there instead of just visiting occassionally I would have dumped the Tundra.

I've done a lot of mods that have helped the ride. It's much better than stock, now, but still much worse than my 01 Silverado with nearly an identical wheelbase was.

I still like the Tundra, but if the bed bounce isn't fixed will probably buy something different next time. It's that bad.

Please list your GVW on the Chevy......my WAG is it's in the mid-upper 6,000 pound range.

Tundra DC 5.7 TRD 4x4 is listed as 5520/7100.

Silverado ext cab Z71 4x4 is listed as 5266/7000. Slightly better payload, but very similar weights.

I wonder if Toy changes springs/shocks when changing GVW.

The CrewMax has a 7200 GVW.......

I still stick with the over damped/over sprung rear theory.

Ditto!!!

Weird, I just held a pencil between my thumb and forefinger at one end and started bouncing it up and down and you wouldn't believe how it was actually bending and flexing in the middle!!! Try it.

Seriously, steel frames will flex and they do give. Even a W24x94 used in the construction of a highrise has some flex under load. However, the amplitude would have to be so minimal on the Tundra frame that I seriouly doubt it flexing is responsible for all the fun. And I seriously doubt you would have been able to actually see the very minor deflection with your camera.
