Annoying bouncy ride on concrete roads

It's been a couple of weeks since I picked up a 2019 Tundra. I have experienced a really annoying bouncy ride that only happens when I drive on concrete roads in my area. The ride is nice and smooth when I drive on asphalt roads. I've experienced the problem on at least 3 different roads in my area. And the problem lasts for miles, not just a little section. On two of the stretches of concrete road there was a short patch (like 150ft) of asphalt repair. As soon as I hit that patch the bounciness stopped and as soon as I get back on the concrete it started up again.

Has anyone else experienced this?

Specifically I have encountered this in Colorado. Today was on I-25 between Denver and the Tech Center. A few days ago it was on 285 in the Conifer area.

I suspect there is some interaction between the distance between the front and rear tires and the length of the concrete sections of roadway. Changing speed (in the 45-70 range) seems to have only a minor impact on the amplitude of the bouncing. But it's really annoying at any speed.

 

Yes... I know exactly what you're talking about. I'm almost certain it's the shocks. I had a 15 SR5, and my wife needed a sports bra on segmented concrete highways. I couldn't believe how much it shook the truck. I bought a 19 Pro and it's 95 percent better, virtually non-existent. I'm pretty sure the suspension is identical other than the shocks.

 

Search "bed bounce" here.

 

Concrete roads are poured in sections to allow contraction and expansion, and to simplify road construction. As each slab settles over time there are small variances in surface alignment. Since they happen at a specific interval you’re going to notice them in some vehicles. The Tundra is a particularly bad offender in this category, the wheelbase, leaf spring pack, and frame design seem to get into a really annoying amplitude of movement over these concrete expansion joints at highway speeds.

If there’s a cure I haven’t found it yet with this truck. I’ll bet the 2022 will ride much much better though on those progressive rate coil springs under a fully boxed frame.

 

It definitely helps. The oe shocks are garbage, the pro shocks are more plush yet controlled. With my icon shocks, its a little better but was still horrible.

the issue is the shape of the frame at the tail and the wild flexing of the frame. The oe shocks definitely allow it to get out of control.

Coachbuilder shackles did help though dramatically

 

Thanks everyone. At least I feel better knowing I didn't buy a used truck with its own special issue. Now I need to send a request to Apple to add a "Avoid concrete roads" routing feature for their Maps app.

 

Coachbuilder shackles with the poly bushings will help eliminate the bed bounce.

 

I just read through the Bed Bound Fix? thread. The Coachbuilder shackles change was mentioned a few times. I have no idea what that is or does but I'm off to do some research.

BTW - there were several mentions of adding weight in the bed to help with the bounce. I experience the problem just as badly while towing a 5600lb trailer with a 550lb tongue weight. But I do have a WDH so maybe that largely negates the tongue weight with respect to the bouncing issue.

 

I driven on many segmented concrete roads, towing, unloaded and never experienced it. I have a 2021 but I also have a transmission cooler......

My ‘20 gets a little bouncy on concrete freeways, do not really notice it on concrete city streets.

 

Ummmm,a friend say pics or it didnt happen?
Of the '15 I mean and for science of course.

 

Not really what I meant but OK.

 

that bed bounce is really common on all makes and models of body-on-frame trucks. it is more pronounced when unloaded.
there's a few sections of freeways here in vegas that give all trucks the bed bounce.

it's funny because i also observed that my bed bounce is more noticeable when the pavement is hot, so mainly during warm summer days. when at night or cool weather, the bed bounce is barely there.

 

Pics or it didn't happen - pre and post sports bra

 

I know, but I ain't posting my wife's tits.

 

Comments without pics are Moot

 

I understand but we are cheap here for this sort of thing too so no apologies for asking!

 

All pickups bounce more when unloaded, but no, the bed bounce that tundra owners describe is NOT universal. My 03 Silverado had nothing of the sorts at all. It is not rough ride, it is harmonic disruption

 

my truck and previous trucks only bounce on certain sections of the highway. and only on certain concrete parts lol i've never owned a chevy so that's the only one i can't comment on.

 

If you ever see a 99-02 era ford superduty on the freeway, you can visably see it as well, the extreme flexing in the frame causing the cab/bed to be almost hitting one another.

the tundra frame is flexing similarly, not as bad though, at least our bed isn’t slamming into the cab.

 

oh yea i noticed those a lot on older fords lol. the bounce is crazy and i feel like their bed is gonna come off the frame. my 2006 f250 bounce was so bad. my gifted female riders with a big personality really feel it lol. that and partnered with the straightpiped diesel...it was not a comfortable ride. me? i loved it haha

 

We are definitely looking at the wrong problem. The problem is NOT the poor design of the tundra resulting in bed bounce on the freeway. The problem IS the lack of a chesty woman riding shotgun

 

I've owned 3 Tundras and they all did it. My current 2017 is the best with Ironman Foam Cell Pros and coachbuilder shackles/poly bushings. I think if I wasn't running E rated tires it would be a little better. However it's not terrible and far better ride than any heavy duty truck I've ridden in.

 

that's it! lack of chesty women. our trucks and highways are 100% perfect. lol

 

Prior to getting this '19 Tundra a few weeks ago I had a '15 Tacoma with a topper. 6 years, 80k miles between both coasts and up to BC and I never once experienced any kind of bounce. The Tundra bounce I'm getting on certain roads is loosening my fillings.

So I looked at the Coachbuilder shackles that some people claim have helped with this issue. I see that they raise the rear of the truck when installed. Is there a version that doesn't raise the truck? I have a WDH for my trailer and it's already at the lowest point on the shank. If the rear of my truck gets raised the trailer won't tow level.

 

There are sections of the 101 in the east valley that made me wonder if there was something wrong with my truck! I finally realized it was happening at and only at the same sections of that road, and calmed down a little.

 

Mine does the same thing on concrete. I can’t drink coffee for 5.7 miles.

 

I know exactly where you are talking about on I25 and it's awful. The road justs sucks, but new shocks did help my ride.
