10-35 MPH rumble strip vibration revisited

This is present since i buy this truck new !

 

The up and down shaking, worse on acceleration is what I meant.

 

Exactly... Sometimes it shake on steering to.
After 4-5 kilometers... The truck is hot and run like a new....

 

It sounds like your tires are flat spotting, after it sit's for awhile. Don't know what tires you are running, but mine do that when it sit's over night. After a few miles smooths right out.

 

What is bad, i try three différents sets of tires. Original Toyo A30, BFG KO2, Nokian hakapelita. And Toyo A30 again on another set of original wheels from another tacoma and still have this problem...

 

Well I threw it out there, but with you trying three different sets tires, you have me curious what it could be. It would be strange that all three set's flat spotted. But not out of the question, a lot of tires do flat spot fast. Lower the tire pressure the less time it takes sitting to do so. With it shaking on steering for the first miles/kilometers, that's a typical flat spot shake. Is the engine running smoth? you mentioned the more you accelerate worse it gets, right?

 

The engine run smooth. Yes, more i accelarate more it shake. It more noticable after 60kph, and worst around 80kph and more.

 

You mentioned in post #43 smooth when truck is hot, no shake.

 

Yes!

 

No good news about the vibration I talk directly to Toyota Corp they talk to the dealer they have my truck for 3 days repjace rear drums..... STILL HAVE THE PROBLEM No way a new truck have that issue, not even a old truck I call again Toyota Corp today , waiting for answer.... IS UNACCEPTABLE A TRUCK WITH THAT ISSUE. I RECOMMEND OWNER WITH THIS PROBLEM CONTACT TOYOA ASAP

 

I have a 2017 TRD. It came with a 2” lift and shook like a rat crapping razor blades from 20 mph - 35 mph. Installed 2° shims and that took 90% of the vibe out. I’d like it to be 100% gone. Bought the ole tilt meter but waiting for temps to drop under 107 to crawl under her for fine tuning.

 

Ok, mine when driving at 65 o70 MPH and apply the brakes soft touch, do feel the vibration also now if i apply hard do nothing how that issue can be normal?

 

You have the defect

 

my truck just went in for the third time over this issue...


I have had the TSB for the rear leafs performed... It did help.. A lot.. But it is still there..

The second time was a road test with the service manager, and I agreed to see if it would worsen... It hasn't really since that time...

But there is occasions where the rear end breaks out into a pretty good hop while braking sdo I just had it back in yesterday..

They removed my rear drums and used a dial indicator to measure the roundness and its within spec... They also did it to the front rotors... Also within spec..

The service manager is working with me on this. He agrees it shakes a bit more than he likes to but since its all within spec his hands are a bit tied..

He has made calls to Toyota engineering and we are going to start throwing parts at it after I live with it a bit longer..


At least I'm documented... So if something comes up even when I'm out of warranty, he says they will work with me on it because I have been patient and reasonable.


Its not like its intolerable... I've had worse quirks on new vehicles than this I can tell you that much.

I've learned to really love the truck...

This is really the only issue I've had..

fuck it..

 

Still there in the 19's!

 

Sure is

 

Just got mine 1/25. Noticed this. I'm under 400 miles.

 

Wow, just by reading everyone's post. I think it's best to just contact Toyota corp before even stepping foot into a dealership.
Such shame, for such well-known company. There quality has downgrade significantly.
No wonder their sales has droopped 7-8% compared to last year

 

I believe I have the same issue, but with me it started immediately after the dealership installed my OME 90000 & 886. I took it in and they did something (I'll edit this post when I get the paperwork) which reduced the intensity of the vibration but it is still there.

At first I didn't mind the vibration, I was only concerned because it shouldn't be doing it. Now I'm getting annoyed because I want my truck with less than 2k miles to drive smoothly.

 

Took mine in yesterday, they test drove it and told me it was normal.for the Tacoma to feel that way.
, Like really $40 thousand truck suppose to feel this way. 800miles on the clock. SMH.
