Shudder

[labrunner_t4r_]

My apologies, I missed it if you had previously stated but what is your current warranty status? You are no longer in the 3/36?

Bringing it in, state the reason why you are bringing it in so that the work order shows exactly that, 'customer states ongoing issue regarding,' and leave it at that. Let the dealership's service department make suggestions and then when speaking to them state what it is you want. That way the paperwork will reflect the issue over and over again. Its key having the paperwork state the issue of why it is you continue to bring it in and do what they request.

I am under the 3/36 still, and my understanding is there is a powertrain warranty up till 60k, but I might be mistaken. I'll have to start ensuring that the paperwork says what the problem is. Its just what I've had done on the paperwork that I have. Guess that was a dumb oversight on my part. The funny thing is that when deriving it today the shudder seemed weaker. Very hard to notice when driving forward, but still noticeable in reverse.

If you make your appointments online then you can write down exactly what you want to have appear on your paperwork. Thats a good option.

Any chance you replaced one tire separately?

Not a bad idea... I'll make sure I do the "add note" option next appointment. No, I haven't changed just one tire, but they did say my left front was pretty well out of alignment at the first appointment. Maybe it was the tread wear? I swear I'm going crazy, but I'm about to either prove that theory right, or blow it out of the water. I'm swapping my wife's Tacoma tires onto my 4Runner this weekend. If its a tire issue, that should tell me right then and ther, right?

I had a Raptor where the front tires and rears weren't the same tread, and it would shutter a bit at times, and 100% in reverse. Turned out that was the culprit. 4 new tires and the issue was gone. Expensive thing to test though.

Ouch, yeah I'm not ready to upgrade to the Ridge Grapplers just yet. There's still quite a bit of tread left on the Terra Grapplers, so we'll see what happens when I switch the Tacoma tires onto it this weekend. But it definitely feels worse in reverse. I'd take a tire/tread wear problem right now over a transmission issue though lol

Don't know how true, but according to Ford, the stutter associated with uneven tread did take a toll on the vehicles various components. What specifically, I don't recall. Just a heads up. Good luck. Let us know how it goes.

So good news, it was a tire issue thank God. We swapped the tires over from my wife's Tacoma and when out driving ther was no shudder at all. Put my tires back as they were, and the shudder was back in full effect. We ended up taking the back right tire, putting it on the front left, the back left onto the front right, and the two front straight back. The shudder is there, but nowhere near as strong, and you can tell its no longer towards the front of the vehicle. So, one of the two front tires is jacked up in some form. Looked at them off the truck and the tread looks good. Neither rim looks bent. Maybe a faulty tire with something internally screwed up? All I know is I'm going to ride it for a few hundred more miles to see if the tread wears down more evenly. If not, I'll be going back to Toyota to see if I threw a wheel weight or maybe a belt is screwy? I'm just happy to know this wasn't a transmission issue. That had me sweating the fights with Toyota to come, but I still appreciate the help from here. You guys at least kept me sane until I could figure this out.

Good stuff. Thanks for the update. Worst case, you can buy tires from Tirerack and they will shave them down to the tread depth you like so it matches the other tires. At least they used to do that.

Fighting Toyota is a losing battle. Glad we didn't have to go that route.

I have exact same issue on exact some ‘19 Pro with original tires but mine occurs between 50-60mph in 5th gear. I do have access to trying out some other tires and wheels as my girlfriend has. a ‘17 SR5 and Mom has a ‘18 Off Road. We are truly a 4Runner family! Let the wheel swap begin!!! Thanks for posting this and hopefully mine resolved as well.

So if wheel swap takes problem away all is good as I was planning on replacing tires anyway. They are only a P metric and 35psi max. Not sure why Toyota spec d them to the Pro? Probably because they were cheap.

Gotta say I had a pair of Nitto Ridge Grapplers on my old FJ and loved them. I haven't been as impressed with the Terra Grapplers on the Pro so far. Now with this, they're definitely off the Christmas list lol.

Ok just wanted to report this in. I just replaced all the original Terra Grapplers with KO2’s in stock size and c load rating. Problem completely gone! Wondering how many Pro owners have had the same problem with the original Terra Grapplers??

Tires can do some unexpected things- had new Ford Taurus way back- after some miles accumulated it would pull to the right. Alignment was checked and on a guess the dealer swapped the 2 front tires left to right. It then pulled left!
Tire looked perfect.
They replaced the one tire and all was well.

 

[Kamalani Mahie]

I had similar issues with the "OEM" Pro Terra Grapplers, although not as bad as you. The quality of the tires is crap compared to Nitto's other tires and other brands tires. I replaced mine with KO2's and had no issues after that.

 

[tls3601]

I guess we all forget how dramatic the effect good or bad tires have on any vehicle. The 4Runner is such a smooth driver on the road we get spoiled so when something doesn’t feel right we notice immediately.

 

[Captsolo]

2019 truck is new. Take it into dealer. Get a video of when it happens and at what speed.

 

[Jivewalker]

For those getting them, make sure you rotate those KO2's on schedule and in the correct pattern. They are great tires but they have a tendency to cup and make noise if you don't rotate and are near impossible to get back in shape. Ask me how i know.

This is interesting - I just brought mine in (under ToyotaCare warranty at 101,000) and they're replacing the torque converter. I was getting really bad shudder (honestly more like bucking) when accelerating between 1,500 and 2,000 rpm. Coasting or light acceleration - no problem, step on it - no problem. Just in that range. I'll post an update when I get it back later this week.

 

[Nobody Special]

Appreciate the advice... I had an FJ for 6 years before this 4Runner and never had a single problem. I did notice my wife's '19 Tacoma has a really rough sounding idle, only to find out that's just that 3.4's personality. I'm going in tomorrow first thing in the AM for a drain and flush, I'll post on here if there is a noticeable difference with new fluid. Hoping this isn't something that I'll have to accept as a "quirk" since now I just cannot ignore it everytime I drive lol.

If set up properly, you'll never feel it, or hear it again. :bounce:

Yep, replacing the TC fixed my issue (although then they forgot a spring in the 4wd shifter, so it would fall sideways in 4x4 - so it had to go back :jump
