Bed hop, has anyone found a solution?

I have an ‘18 SR 5.7 Doublecab 4x4 long-bed, bone stock, 5k miles. Denver metro. Bounces like crazy on that light colored, concrete looking, slab, expansion joint? If you’ve driven around here you know what I mean, I-70 from Limon to Denver, I25 20 miles or so north & south of the Loveland exit. Has anyone found a remedy?

 

I have same issue and next week I'm ordering Coachbuilder shackles I've read those seem to help

 

I haven't tried new suspension but the extra weight of the flat bed I have rarely results in the tundra twerk.

WELCOME

 

Ok, don’t want a flat bed, seems like a harmonic problem, maybe it’s under dampened, maybe it’s overdampend? It looks like there are more than a few Colorado members on this site, curious to know if they’ve discovered any secrets.

 

I’m not sure what the point of this video is? This is a 2nd gen truck, I’m posting about a new 3rd gen Tundra. Additionally, is the bed moving independently of the cab on a very rough road necessarily bad?

 

Well, backnin the day, the answer was 'weight in the bed' which still works best. In my case, the bedrack and RTT I added (285#) make it ride nice. My grandfather used to lay a large flat piece of steel in the back just for weight.

Not a solution for everyone, but it does work.

 

I'm not qualified to divulge the answers you seek. Eventually somebody with knowledge will be along to offer suggestions. I just wanted to post the video. Sorry I didn't know this was a cereal thread. I'll leave.

 

See told ya @Superbrad

 

Weight does help, I noticed with a couple dirt bikes in the back it was smoother. Thing is, the wife uses the truck to commute to Laramie, WY about every third month. She doesn’t want to be responsible for our bikes. I’m comparing this ride to that of my ‘04 F150 Heritage Xl, I like the Tundra better but it is significantly worse on these types of pavement.

 

Haha, don't leave. When someone posts late at night, especially on a weekend, threads usually "die" before anyone that knows the answer gets a chance to see and respond. Every well-meaning response gives the OP's post a little longer to be seen.

Anyway, mine was a hoaky (albeit real) suggestion. But probably only someone with a farm or some reason to keep something heavy in the bed would appreciate it as a solution.

 

Maybe call Toytec as a start to see about suggestions incorporating new suspension. Otherwise you really could cut a piece of steel to fit the bed, but it'd rust over a winter in Wyoming.

I just suggested Toytec because they're maybe not far from someone with a commute to Laramie.

 

Hence the reason for my post lol. But he was super cereal so...

Get sandbags . Lotsa bad memories on I80.

 

I appreciate the input but I don’t believe weight is the real solution. This truck is not stiff, it just responds poorly to certain types of pavement. It’s probably a design flaw and possibly remedied by a suspension redesign.

 

Definitely. Everybody here is going to recommend toytec cause he's in your area. What else do you do with your truck?

 

We tow a 12x6 motorcycle trailer to the vintage MX races, 3-6k lbs, 4x per year. Road trips unloaded, snow days, truck gets under 10k a year.

 

2nd gen and 3rd gen are same frame same suspension so they work they same

 

I’m in Colorado and have noticed the same bed hop. Especially I25 near Castle Rock. It’s always on the grooved concrete paving for some reason. The ARE topper I put on seems to lessen the intensity by about 30%. You can see the bed move several inches in the rear view mirror. I watch other trucks on the same section and don’t see their beds bouncing. Must have something to do with the wheelbase of the tundra and ripples in the concrete that must occur at a certain interval.

 

I am in Denver area.. and have only had my truck a couple months. I have not driven on those sections.. but I do know they used to suck when I drove my GMC over them

 

I’m in Denver and know exactly what you’re talking about. I think it was worse with my double cab than it is with my crew max, but it’s definitely still noticeable. Unfortunately I don’t have a solution, just something I’ve got used to by now.

 

Found this on a site called tundrasolutions.com from 2010. I have not tried this myself, but, also question whether having the tire slightly loose is a good solution for the long term: "I'm telling ya. It' WORKS!. at least for me. Grab your spare tire tool (no, not that one ). Lower the spare a couple turns. Just enough to where you can take your 4 fingers and reach up under the bumper.. TOuch the spare and pull it towards you with just your fingers. Like you were motioning someone to pull forward. The tire should easily pivot upward. If you have it lowered too much it will feel like its dangling and you don't want that.

You'll know you have it just right when you shove down on your tailgate and instead of it springing backup a few times, instead it will come back into place and stall out right before your eyes. The spare is actually canceling out the bounce.

It's like having 2 people on a trampoline. Remember how if one person came down just as you hit you both canceled each other out and didn't get to bounce back up.

Give it a try."

 

Hmm... So the spare tire would supposedly act as a damper.

I guess thats not an impossible theory, but i wouldn't think that it could respond fast enough in the senerio that is causing it. I really have no idea though, but i do find that idea interesting.

 

36 and 25 are awful...

 

Welcome from greeley.... I have an 07 with north of 180k D.C. W/ 6.5 foot bed, stock as a rock. I have no issues with the sections.... maybe my springs are just super warn in...

 

I’m going to guess that it’s the solid mounted spring bushings. They are molded into the spring eye and the liner is knurled to grip the insides of the shackle so they don’t allow the shackles to freely rotate like they should. I have a set of Toytec poly bushings that I’ll install soon to test this theory.

 

aftermarket leaf springs would help. It did with my lift. Put the icon rxt pack. Super smooth

 

Have the same problem on my 08 double cab bounces like crazy , I 76 by the flea market I 36 heading towards Westminster . I thought I read somewhere that Toyota was selling rear cab mount bushings that were softer I don't Know if that would fix it or not. Let's try to keep this thread going and find a solution.

 

I have a stretch of I25 in front of my office through COS and went out an hour ago and loosened my spare, then ran down the interstate. Not sure it was much, if any, better. 2009 DC and it's bone stock (TRD Off Road) shocks with KO2 tires on factory rims. I do not have a rear sway bar and only have a tonneau cover in/on my bed. I may have to look at getting some sand bags to put over the axle and see if that helps.

 

I am from Nm, and go to Denver alot. I have it on I40 here and I25 up there, around Castle rock is horrible 4 me. Did it on my '06 dc, '14 dc and now '18 dc. Weight doesnt help me (use mine for work and am always hauling weight), p metric or load range e tires dont change it, current truck has bilstein 6112-5160 shocks, toytech shackles and poly bushings and that didnt change it. Slowing down is the only thing that works for me.

 

I do notice speed helps. Either slowing down or speeding up.
