Rear suspension bounce

I have a 2021 Tundra that is currently at the Toyota dealer for a problem they don’t seem to be capable of fixing. They’ve had it for a total of 12 days over 3 different trips. This most recent trip, they gave me a loaner, a brand new 2023 SR5 with 4k miles. I’ve been driving the truck for 5 days now and it’s made me consider trading mine in for a 2023. It’s got some positives and negatives. Positives: it’s smooth, fast, nimble, quiet, and handles great. Negatives: it sounds like a minivan when you step on the gas, it’s completely gutless until 3k rpm’s, and the worst of all… the rear suspension is super bouncy!

The rear suspension bounce is a deal breaker for me. It makes the tailgate rattle over bumps because it’s so bad. If I put the rear window down, it is very loud, passengers have even commented on it. Today I got back from 3hr round trip ride and I had a headache from the bouncing rear suspension. It’s not like a vehicle with bad shocks, bad shocks produces a slow bounce, similar to a boat floating through some waves, these are sharp rather jarring follow up oscillations after hitting a bump. Is this a common thing with these trucks? Do the TRDPros suffer the same issue with the Fox suspension. I couldn’t drive this every day for that reason alone, but if a different trim level took care of it, I would consider going that route.

 

I noticed that my 23 Limited has pretty soft suspension front and rear, but it’s a TRD Offroad. Did the SR5 you drove have this
package?

Mine definitely doesn’t bounce like you are describing, but I do think I’ll put a stiffer set of springs in the rear now that I have a camper shell on it.

 

Sooo... Let see..

1. It's possible that the truck you drove may have a defect.
2. Is it regular suspension or Trd suspension? Find our and try another one. Also try Trd pro as it will be absorbing bumps much better.

You can also upgrade the shocks so it absorbs bumps better - I got regular suspension no trd and before I added weight with camper, it was terrible and jarring at handling potholes.
3. Are you interested in adding a camper i I tonneau cover? There would fix the rattling bed issue. It did for me. There's a big thread on fixing this rattling bed issue by yourself as Toyota wouldn't do it because no tsb from corporate.

4. Try to test drive other brand new tundras to see if you can find one with better suspension and no bed noise. Do more research on this forum and look for other common issue such as wind noise on freeway, humming noise from rear when driving above 80mph, and other rattles etc.

By the way, I would wait to buying new Tundra until they figure out what's causing the bearing failures... See sticky thread

 

Look at emergency flasher switch. If there is an up and down switch to the right of it then that truck has rear air suspension. They are bouncy and bang over larger bumps. A simple adjustment corrects this problem. If it has air suspension that truck may not have had the correction done yet.

 

I have the TRD Sport and no issues with it at all in this regard. So consider other trims since suspensions do vary.

For acceleration what drive mode are you in? Give Sport a try and see how it goes. I have no issues chirping the tires when the mood or need arises.

 

I’m having the same issue. I have a 2024 Tundra SR5 with the SX package. I was super excited about the truck. However, interstate driving is TERRIBLE! Even my wife noticed the insane amount of bouncing in the rear suspension. Has anyone talked to a dealership or had anything to fix it?

 

My '22 Is a TRD off road with that suspension. It was super stiff in the rear when we first got it but after adding 1" spacers, it became much more enjoyable.

There are differences with the suspension, I drove an SR5 but found it a bit stiff. My Limited is nice now even with the stiffer tires. The. only thing I don't like are those highway transitions that cause a bit of side shift of the rear end. My BMW does that as well to a lesser degree and other trucks, I have had, did that as well.

It is even better if you have a bit of weight in the bed to get the suspension moving. I have about 200 lbs. of stuff bolted to the truck like the cover/rack and skid plates and running boards.

 

Wow gutless under 3k rpm, its peak torque is 2,400 rpm

that’s interesting, mine doesn’t seem like that at all

platinum avs has the best ride as you can dial comfort mode if that’s what your looking for , it’s comparable to the ram which has the best ride hands down. You can then dial normal or sport if you want it tighter

 

Glad I wasn’t the only one to experience it. That 3hr road trip I took, I couldn’t wait to get out of the truck, and that was only 1.5hrs each way with a 3hr break in between drives. I’ve decided to keep my 21 instead. I’ve made 6hr road trips in the 21 and enjoyed every minute of it. A brand new $50-70k truck shouldn’t need suspension mods to not give me a headache from driving it.

 

No issues at all with my TRD OR Limited.
Maybe you needed to talk yourself out of a new truck?

 

It just sounds like the SR5 suspension is shit compared to the TRD or limited.

 

Seems to be the case. Unacceptable at that price tag.

 

Quite the opposite in fact, I was looking for an excuse TO buy a new truck. The fact I’m not the only one with this problem shows it’s not an isolated incident.

 

Sounds like shocks are not properly tuned for the coils and unsprung mass.

 

There are quite a few TRD Offroad and some TRD Pro suspension parts for sale. If you like the truck, you can always grab those and stick them in.
