Really Toyota? Really?

I need to rant so if you're reading this you get to listen (or run away now). Perhaps this will quickly degrade into a brand vs brand pissing contest.

Toyota for years has been plagued by vibration problems in Tacomas, 4Runners, FJ Cruisers and Tundras. Ultimately most of the problems boil down to a needle bearing in the front differential that is being forced to support the CV axle due to a cast housing for the spider gear in the differential. Toyota has, for years, called this vibration a "characteristic" of the vehicle. Often times the best solution an owner can get is having the dealer continually replace this needle bearing over and over until they're out of warranty. East Coast Gear Supply has come up with a more permanent solution in a bushing that replaces the needle bearing. It has tighter tolerances and prevents the CV axle from vibrating.

During one of the autoshows prior to the launch of the 2016 Tacoma Mike Sweers, Chief Engineer for the Tundra and Tacoma, was asked if this problem would carry over to the 2016's:

"With regards to ride quality, we asked Sweers if the hasslesome driveline vibration issue is finally resolved. Confidently, he told us “if you find one with it, I’ll buy you dinner!” He said the problem was an engineering and manufacturing issue throughout the previous generation. The new truck has different engineering and new spring angles which eliminate the problem."

Well guess who owes me dinner?

Over the last couple of weeks the exact vibration that so many others have noted has popped up in my 2016. I took it in to the dealership for inspection and they verified that it is the CV axle vibrating within the bearing. The fix is the same as well, replace the defective bearing with a new defective bearing. On the Toyota boards some owners are getting as little as 500 miles out of new bearing before the vibration returns.

Looks like I'll be tearing into my new, still under warranty, 15,000 miles on the odometer truck and replacing the bearing with ECGS's bushing. This is a true first world problem, and I'm whining, but it still irks me. Get it together Toyota. Mike Sweers owes me a steak.
 
Dude, I would totally get that steak dinner. While it does suck to have to pay out of pocket for a permanent solution to the vibration, at least it'll be a permanent solution.

Love Toyotas but damn did they miss the mark in some key areas on the 3rd gen.
 
Where exactly is this vibration felt? I get occasional side to side shaking in my steering wheel that I always attributed to my old tires being out of balance until I got the new tires and it still occasionally does this albeit a lot less.
 
That's one of those infuriating details where there just doesn't seem to be a justifiable reason for them to keep producing that part in the same manner, yet they do. Usually, it comes down to some unwillingness to change something in the assembly process to save 2 cents.

Although no one is more notorious of that behavior than GM and it practically did them in during the 90's with badge engineering.

But it's a common thread thru out the auto industry. Truth is, a lot of the underpinnings of most vehicles are over 20 yrs old. The "new" is usually more polish than not. True improvements and refinements don't happen frequently.

Like why the hell the 3rd gen has rear drum brakes. SMDH on that one.
 
It was amusing, when questioned about that decision, they answered that they were better for offroad use...

Really Toyota!?! :rolleyes:

Interesting that my 25 year old Cruiser has disks.

It depends on the speed. At 15 to 20 mph the vibration can be felt in the floor board and the steering wheel. It's gotten to the point that it feels almost identical to going over rumble strips on the highway. It's actually vibrating enough to create sound at 15 to 20 mph, sounds like a low growl coming from the drivers side of the front differential. At 50 to 60 mph the vibration comes through the steering wheel, and if you know what you're "feeling for" you can feel it in the floor board and seat a bit as well.

Pure cost savings here I'm sure. There's probably a warehouse full of drum brake parts owned by Toyota in downtown Tokyo that needs to be gone through before the next redesign where putting disc brakes on the 4th gen Tacoma will be hailed as revolutionary. They also did it to make me dread the day I have to do a rear brake job on the truck...I hate servicing drum brakes.

If anyone wants to see what's going on here's the why, what and a fix:



 
Funny, I have the bushing and install tool in my garage but still have not put it in. At this point I am just used to driving in a paint mixer. One day I will get annoyed enough to install the damned thing.

This is brilliant. I have some paint that I need to mix and use when I get home. Problem solved.
 
I guess i'm out of tune with the vibration. I can't recall ever feeling it, and only time I've ever heard of it is on the boards.
Everyone has a different threshold for what drives them nuts.
 
By the way, i still have the removal tool if you want it so you dont have to buy one.

Absolutely, thank you! I'll be in touch when I order the bushing and get home from California.

I think it's interesting how it seems to affect different vehicles at different times or even not at all. I would assume that it has to do with all the variables, the metallurgical make up of the parts, the tolerances in the casting of the housing, viscosity of the gear oil in the diff, etc, etc. There are owners out there who have claimed the problem at as low as 500 miles. I had absolutely no vibration up until two or three weeks ago. It started small and has gotten progressively worse. So that's 15,000 miles with nothing and then the problem began.

Yup. Drove my 2nd gen for 11 years and never had this issue.
 
I love Toyota's, so much so that we bought my wife a 2016 4runner a few months ago. That being said, I believe Toyota no longer believes they need to innovate since they sell everything they make. How in the hell does a 2016 SUV still have a 5 speed automatic transmission? People have complained about the nose diving front ends forever, still has not been resolved. Same thing with the vibrations. I was hoping that the emergence of the Colorado/Canyon would help push Toyota to start caring again.....
 
Sometimes I think people just expect to much. Remember when a manufacturer starts going for hardcore comfort on the road they immediately stop making them trail worthy and you now have a car in the guise of a truck. I'll take my reliable work horse of a trail rig any day.
