oh no....TSB-0171-16 Driveline vibration

Feel like this issue is present in my 2021 4x4 DCLB SR5 too.

Hard to pinpoint where and when the vibration is coming from. I've been on otherwise smooth roads and I'll just have the cabin feel shaky and see bags on the floor wiggling around, cup holder items twitching, etc.

It's not horrible, but definitely not how a new vehicle that cost me 37k should be driving. It drives like a Sherman tank.

New Cooper Discoverer tires and balancing did nothing, and before that the Toyota dealer drove it and said it was "in spec" and didn't do anything else.

Trying to decide if I want to print out the TSB and tell them to do it and check the drums, and then if it doesn't fix it I'll just drop it and maybe try a separate alignment and road force balance at Mavis where I got the tires.

If nothing else works I'm just gonna say screw it and assume this is how these SR5s with stiff shocks and not much weight drive and so be it.

 

TJH1224 (& anyone else) - Might I suggest downloading the NVH Vibration Diagnosis app on your iPhone phone or cellular iPad ($99 on App Store) . . . there are a few youtube videos on how well the app works. It shows where different vibrations were coming from and at what speeds and the amplitude of the vibration. For me, it overwhelmingly shows my issue is Driveshaft Related rather than Tire or Engine related.
Your dealer may look at the results and still call it "within spec", but it may help to show you are serious at trying to get this resolved.

Look at some of the youtube videos, and decide for yourself . . .

 

Interesting. I'll have to look into that. I wouldn't think a phone or ipad's sensors are that good.

 

It's a tough one. Our dealer said the same but did find that the brand new rear brakes were jacked. After fixing the brakes, the issue got much better, almost not even noticeable. We then installed Wildpeaks and 17" TRD wheels and the vibration seemed to lessen even more but now the tires are out of balance or out of round. It's been back once for re-balancing today and need to drive some more and take it back again if needed. Also the hood vibrates and the overhead console makes noise. Getting very tired of vibrations! Some people would probably ignore all of this but I just can't. I also kept the stock wheels and tires so I can put them on anytime it's needed if the dealer claims it's my bigger wheels and tires. This was actually a suggestion by them and a good one. Still wish they'd just stand behind their issues instead though. We have a 2017 RX350 that is dead silent. Makes me want to get a second one.

 

I have a 2021 OR and get vibrations only under very specific conditions. Slowing down with medium brake pressure right around 40-45 mph. No vibrations above or below that speed. No vibrations with really heavy or really light brake pressure. It is so consistent that whenever I feel it I can look at the speedometer and see the need right in that range each time.

 

For you guys with driveline vibrations, make sure you've read my post on correcting this:

Post #50 and 51 are the heart of the info.

 

Great info you put together there. How's your video coming along? We had a guy over in the TRD lift thread who was very detailed as you were with the measurements. He ended up just needing a 1 degree shim added but that's with the lift so not comparable to stock height. I may shoot you a PM about our Tacoma but need to get my thoughts together first.

Everyone taking measurements though was using the TSB numbers and not the Spicer numbers you shared, which may lead to much better success.

 

Hey everyone,
New here. i just picked up a 2016 TRD sport. Had a big wobble at higher speeds so i got new tires and it got rid of the high speed wobble.
but now im noticing that when im slowing down on the highway between 60kmph to 30kmph i get some sort of vibration that feels like its coming from my brakes
(not very mechanically inclined) haha HELP!
