So has anyone actually solved the bed bounce/embarrassing highway ride?

I see there's a TSB that Toyota sent out, but it also says it only affects the 2007-10 model years (I have a 2011 model). The bed bounce on long stretches of highway around here is literally sickening (i.e. makes myself and passengers want to throw up after a couple of minutes), and it's embarrassing even on non-concrete spans that you can't hold a cup of coffee in your hand without it sloshing all over the place. I'm trying to plan an active approach in the spring to start to address the issues, since it seems like we're planning on keeping the truck for a while, especially after Toyota did such a god-awful job on the design of the new Tundra.

2011 Rock Warrior, mostly stock. Suspension is stock, wheels are stock, has Michelin Defender LTX tires...may look at swapping these out to P-tires at the next change, although with a boat on order it might not be in the cards. I do zero off-roading and don't ever plan to. I believe there are maybe 1/2"ish plates on the front suspension that the previous owner put on to level the truck that are coming off.

So what successes have you had in trying to tame the ride on these things? I'd like to find an aftermarket cab mount setup, but so far I'm striking out with anything other than OEM...I'm not sure why Prothane would still make mounts for 20+ year-old trucks and not more current models, but there you have it...

 

What cab configuration? Stock shocks are the black ones or blue/yellow or red/blue? Crew models generally have less bed bounce vs longer bed, DC models. And if you have the stock black shocks, those are pretty subpar even when new, very squishy which will make bed bounce worse. Better shocks will help. Shackles may as well. And then for free, add some weight in the bed and that will help.

There is a dedicated thread or two about the issue, found these

Shackles are definitely on my list for the spring as well - Coachbuilder +1 (I have no desire for a lift). It's got the standard yellow/blue TRD shocks, I'm 99% certain they're the originals, so now with 138k on them. I do have a line on a red/blue setup I'm contemplating swapping in...I don't think they're actually any different, but much lower mileage.

It's a DC with the standard bed length.

Thanks for the links, guess I've got some reading to do!

 

Never had any bed bounce issues in my 08 for 12 years. Lifted DC pro comp rear shocks with

 

Welp...congrats?

 

Those shocks are toast at 138k. Got your moneys worth! Those are the off road package shocks, decent for stockers. But with that age and miles, certainly tired. You can often find them for sale really cheap when folks install other suspensions, usually lower miles and the whole coilover assembly so swapping would be easy. But there are some in the marketplace here for sale now for a couple bills

The blue/red are the shocks for the sport package, more tuned for road.

 

That's the plan here...found someone selling a full takeoff set from a 2019 with 20k on them for $100. I would have grabbed them already if I didn't come down with COVID last week....still in recovery mode and they're about an hour and a half drive, not sure I'd be able to stay awake long enough to make that drive right now!

 

Thats a great deal!

 

OEM is often best for Toyota. An exception is suspension though— lots of options. Replace your shocks. If you’ve ever carried a lot of weight in the bed, your rear leaf springs may need an upgrade.

 

Mine has had that issue since it was new. Suspension can help, but the route of the cause is more to do with wheelbase length and the fact concrete bridges and expansion joints cause the front and back to oscillate in a suspension wave. If I speed up it’s less noticeable. But at 50 it’s horrible

 

My '08 crewmax had it bad, the 2020 dbl cab doesn't have it at all. An yeah the stock suspension still sucks but that's a Toyota thing.

 

I put on king shocks and it didn’t really help. Coach builder shackles helped a little. Getting rid of the shitty cooper E rated tires and getting E rated revo 3’s helped a lot. Still get it, but with the cooper tires it was unbearable.

 

Not just a Toyota thing; my '13 F150 would literally have my head hitting the roof if I didn't slow down when going across those @$#$ expansion joints.

 

Fox 2.0 rear shocks on mine cut the bounce by about half on my '16 double cab. The bounce was awful when it had the TRD yellow and blue shocks on it. I used to watch the bed flop around in the driver's side mirror but with the Fox shocks on the rear, it barely moves. Feels like the bounce is more in the front of the truck now... can't wait to get the fronts replaced.

 

My '08 DC had bed bounce. My '21 Pro has bad bed bounce. Stock it did it and it still does it with CB shackles. Always feel like I'm ass twerkin going over rail road tracks

 

It sounds too simple I know but when I planted my heavy DCU cap and Bedslide on mine it pretty much took care of the problem for me.

Then when I load up the cap and add to the slide it seems to get even better but unloaded mone was crazy too.

$20 of sand tubes would likely tell you if weight in the bed could be a fix for you too?

 

Not too bad on mine. Not sure you'll ever totally eliminate it. Soft suspension + heavy in the front + light in the rear + 50-70mph…seems like it’s always going to be there a little. I have the TRD Fox kit, CB +2s, and Firestone air bags.

I notice it but I’ve never had a drink go crazy sloshing around. My kids like to go Ah-ah-ah-ah-ah-ah-ah on the worse sections. Mine is really not too bad unless I’m going slower like @Earthsurfer said.

 

Bed bounce is a pickup truck problem. Get used to it.

Weight in the bed can help.

 

I had a 15 SR5, and now a 19 Pro. The bounce is 98% gone with the Pro. The only difference in the suspension is the shocks.

 

I have no noticeable bed bounce. I'm leveled in the front with 5160s in the rear and a 200 pound rolling cover. There has to be a common denominator there somewhere

 

Negative. I follow other trucks every day over the same tracks and don't see their beds move like the Tundra's. This has actually been a "game" of mine to and from work.

 

I was definitely bad in my 2008 (bought new and started immediately) on certain FWYs/HWYs. At the time I was living in Las Vegas the when the new 215 was finally up and running it was downright nauseating. To the point I'd either slow down till it went away or speed up till it went away (usually around 80mph). Anyhow, I ended up w/a dog box in the bed (about 100lbs), and the bounce and vibration was immediately resolved. Same when the dog box was replaced w/a SnugTop. So, I'd have to say I agree w/either putting cap on the back or weighting the bed w/a couple of sand bags (about 50lbs near each of the rear wheel wells).

 

What is your tire pressure at?

 

I have it on my ‘18 DC with 5100s on all corners. I wouldn’t consider it jarring or unbearable though, just annoying. Certain stretches of highway are worse than others and weight in the back definitely helps. Just a combination of wheelbase, weight distribution, and expansion joint length.

 

I have it on my 15, even with 5160's and shackles

 

I had an ARE cap on my '08 and currently have 300lbs of sand bags in the back of my Pro for the winter. I'll try and get video of the bed bounce.

 

If you have 300lbs in the bed and still have the bounce... I'm not a mechanic or pro by any means, but I would think something is definitely wrong.

My current Tundra is a 2021 PRO. It was delivered about a month ago, and I only have about 1100 miles on it. So far the only "weight" I have in the bed is a spray on liner. I live on the Central Oregon Coast, so most of my "Hwy" driving is on the 101. I don't believe those speeds and highway design would have generated bounce even for my 08 (prior to the cap, etc.). However, I've been on the 5 from Albany through Salem and back a few times, and so far I have not experienced any bed bounce w/my new PRO.

Air pressure has been mentioned, and by your pic, it looks like you have aftermarket tires.... Air pressure didn't seem to matter on my 08 when I had the bounce issue. However, I would think running higher air pressure would make it easier for the bounce to start. So, if you normally run above recommended levels, maybe try airing down a bit and see if it eases up on you. I'd also check to make sure your bed bolts and anything it touches are torqued properly. Finally, if you are still in warranty, maybe take it to a dealer and have them give it a solid once over just to make sure something isn't broke or coming loose on you.

It's pretty easy to attach a GOPRO or something similar to the bed rails if you have them and get some good video of the bounce prior to the dealer or have someone sit the back seat w/the window down and video it. Either way a $50-60k truck shouldn't have an unpleasant ride.

 

I mentioned my Pro had bed bounce when it was stock. Stock meaning the factory tires and prior to shackles. When you go over any rail road tracks and watch in your rear view mirror, you can't tell me the bed doesn't dance around and shake the cab of the truck. I test drove two Tundras in between having my '08 and the current '21, and they also did it. That's why companies are making bed stiffeners via gussets or plates that bolt down to the bed as it's a known issue

 

I think railroad tracks causing shake is different to what most of us are referring to with 'bed bounce' which is caused by seams in concrete roads. At 75MPH on I-25, it was horrible with the stock blue and yellow bilstein shocks. Not too bad with Fox 2.0.

I believe the crappy digressive tuned shocks coupled with captive shackle bushings and floppy rear section of frame makes the issue worse. My old Ram had some bounce on the same sections of road but I could dial it out with the in-cab shock tuning on the Rancho RS9000X shocks. Firming the shocks up actually made it much worse.

 

I'm only referring to rail road tracks specifically as I have to go over two sets twice a day and simply watch other trucks. There's portions of I82 in Washington where I experience exactly what you're stating with the seams on the freeway. I purchased my Pro in Oct of 2020 and it only has 7k miles so I don't see a lot of freeway/highway time.
