Brand new truck vibrations

Go to the dealership first then see what they diagnose. If not happy go to another, if still not happy post what both said here. If still not happy you now have multiple opinions to sort through.

 

I've got a similar vibration(s) issue, bought the truck 2 weeks ago (2018 TRD Off-road) - whole truck vibrates between 55 and 75 mph and then the shuttering during braking. Took to the dealer 1st time at 300 miles they found a flat spot on rear passenger side tire, got it replaced - no difference. Took it to another dealer at 600 miles, they re-balanced all four wheels - no difference, still same vibration and actually seems like its getting worse. Called Toyota USA yesterday just so I'm on record/document whats going on. Dropped it off to another dealer (dealer where the car came from) this morning for the 3rd (hopefully last) time. Unfortunately there is snow on the roads so they're going to have to wait to diagnose until the roads are clear so I'm in a loaner till then.
All the comments above about this being a truck and its supposed to drive like that are BS - I've driven many trucks in my life and the vibrations in this thing are not normal and its definitely not how they're supposed to drive. Take it to the dealer and be persistent. I've got 2000 miles on mine in 2 weeks - I drive alot and am now uncomfortable in my 40k brand new truck. I'm not giving up until they figure this shit out or I get a new truck (Exactly the same as what I have cause I actually love the truck).
Good luck!

 

Should stop here....

 

I really dont understand the negative responses to someone asking a question and starting a discussion. It's a discussion forum. If you don't want to be part of the discussion then don't, no one is forcing you.

No one should ask about rims because they can just go look at some rims? No one should ask about tires because they can just google some reviews? Any question can be solved elsewhere, so why have a forum?

 

And just to add to that... I doubt the OP is asking for a solution (i wouldn't be anyway) on this forum, that would be silly. There is no reason not to start a discussion to see if there are others with the same issue and what if anything they've done to solve their problem. That's what the forum should be about. I just joined this forum and already kinda turned off by the silly negative responses to an appropriate post.

 

Ignore the trolls, they go away when they dont get any attention. Hope you find your answer. Most folks are happy to help on here.

 

The truck is brand new, go to the dealership and see what they say as the visit is free.

You did not elaborate where you feel the vibration other than its at different speeds.

Felt in the gas and or brake pedals at accel and decel? Check drive shaft coupling / U joints for tightness. Could be rotors
Felt in the steering wheel? Tire Balance
Felt in the seat and dash? Noise isolate/motor or cab mount.

Just for reference what air pressure are you running?

Since you didnt elaborate we cant really hazard a guess. I can tell you with brand new offroad tires you might get a vibration for a few miles until the tread wears in.

Take it to the dealership and have them ride with you to feel the symptom first then get back with what they say if they cant find a reason.

Its what we did long before we had forums so the process can still work.

 

OP you doing great. This is what a forum is for to post things about the truck and get good information. Always good to post and see what others may know. Ignore the hot air man some people will try and help and not talk down to you to make themselves feel better.

 

member "Further" proves my point. he took it 2 different places. they threw parts at it for a normal/unknown issue and it didn't fix it. states hes had multiple other trucks. probably none of which were 3rd gen tacos. brings up the for what he paid for it part. then states he wants a new truck which will also probably do the same thing.
unless you've driven 10-15 other 3rd gen tacos how can you state that it is a actual problem or what the vehicle does. just cause you don't like the way it drives/feels doesn't mean its broke or that it will break in the near future. yes many people have complained about these issues. but have any of them been fixed? same with transmission shifting issues. has anyone on this forum actually had their transmission fail? any part of it? or do they all just object to the way it shifts.
I bought my 2016 in july of 16. it has some of the same issues the OP and others have brought up mainly from this post shuddering on decal. on or off brakes. hasn't got worse, hasn't got better.
there has been some talk of rear leaf springs causing this issue. maybe that is it maybe not. how long do you want to spend in a loaner or eating donuts while. Toyota tries to decide if its a defect or customer extra sensitive.

on other note. does anyone know if Toyota uses a PICO Scope? its measures mila g's at seat frame. and can classify them as tire/engine/drivetrain/prop shaft vibrations. and can narrow down where its coming from. and if they are above spec. have used this on 14-18 Silverado's for vibration concerns.

 

If you're willing to make the effort...and a simple diagnostic.
Switch front left tire with rear left...test drive and comment..better (left front tire is out of round or out of balance).

Switch right side tires,...better or worse?...same?..
Sometimes the solutions are simple.
The diagnostics is 90% of the problem

And btw guys,..be nice with the posts.
This fellow is a brother after all...

If he drove say....a Dodge,...I'd get the rope....and drag him to a bridge! (just kidd'n)..

 

Air pressure.

 

The Pico is the mandated shop tool for sensor and network, etc diagnostics. I’m not sure if they make use of the accelerometer accessory. That sounds like a cool idea though. Driveline vibrations are not something I’ve spent enough time studying.

 

You can ask any questions you want to here,ignore the negative responses,you have a warranty on the truck,take it in and have Toyota fix whatever the problem is.

 

Check your lug nuts make sure they are all tight, first of all. Call the salesman that sold you the truck and tell them to get you right in and ask for a loaner.

 

I’m curious to find out what your service department turns up as the culprit , my 2018 sr5 has had this exact same vibration at the exact same speeds . My truck only has 800 miles on it so far , I love the truck otherwise .

 

@mds08

Mark, do you want to chime in on how the vibrations felt on your truck with the missing wheel weight on the rear tire?

 

There are a thousand reasons why a truck vibrates and there will be a thousand answers that will be absolutely meaningless to the service department. There is nothing wrong with being informed but being informed with the wrong information is just as bad as not knowing anything. If your serious about educating yourself on the mechanics of your Tacoma get a service manual and start reading. Your assuming that the service department is going to bullshit you even before you visit them. Go in with an open mind and work with them. If they dont resolve the issue then try another dealership or call Toyota customer service.

 

There is a leaf pack replacement TSB that has new leafs that fix the driveline angle. (Likely your issue), could also be off balance wheels

 

I lifted the truck with bilstBil 5100s, 1/4 shim for taco lean and a one inch block in the rear, added the ECGS clamshell. Put new 265/70/17sl Toyo open country at2 on trd pro Sema wheels. Had a slight vibration at 53 and around 64. Thought it was a rear tire out of balance, left rear out a little. Also did a front diff drop. The truck felt great after that. The vibe felt in the pass. Seat shaking and I could feel the vibe mostly when I rested my left leg on the door panel. They did a diff drop at first and then re road forced all tires. It was so slight of a vibration I only felt it on certain type of roads and when the tires were cold. I have such a short comutec to work I didn't feel it all the time. Now 300 miles on the re balance all is well. The shop was for sure a diff drop was the answer but it was definitely a help. I got almost 3 inch in the front when the new tires were on.

 

I appreciate the input, both positive and negative, even if you don't understand my point if view for asking. I'll report back after the dealership checks it out on Tuesday.
