Replaced driveshaft...still vibrates

Just had the driveshaft replaced in this 2013 tacoma for a vibration on exelleration and 30 to 40 at the dealership ....still has a considerable vibration on exceleration from a dead stop.30 to 40 vib is gone.wtf is wrong w these trucks.!!?? Its a brand new drive shaft from the dealer!!!

 

A good driveline shop can usually figure this stuff out.
Be prepared to pay a good bit for it. As it takes skill and knowledge to “perfect” a driveline.
It’s not something a lot of shops specialize in. That’s why it cost a little more.

Since you have a 2013, your likely not in warranty unless you are extended?
I’d pay a little more once, and forget the 2x 3x back to the “other” shops.

 

The 30 to 40 vibration is gone.but its def there on exelleration. Gone on downshifts too....it was $1000.and ya i think with them sayin that it w fix it that is enough for it to be their problem to diag and fix cuz i allready paid $138 for the diag.

 

I live by suncoast converters i bet they can figure it out . But ya itll cost

 

If you spent $1000 to have it “fixed”
And it’s not fixed, take it back.

As for the rest of your question. @whatstcp had good suggestions.
I’d mention those things to them, maybe it will help them figure it out sooner.

 

Also worried about it ruining my assend or wearing something out premature

 

Wow, you could have bought a Tom Woods one piece for that.

 

I had the whole assembley

I got 2x4

 

Still could have used it. Good luck with your truck.

 

You spent $1,000 on a 2 piece driveshaft???? Custom built all aluminum 4" one piece only cost me $900.

Water under the bridge....

My guess is that you have OEM leaf springs and they are getting weak. On acceleration the front half of the spring is warping because of axle wrap. Put a GoPro underneath recording the front of the leaf spring between where it attaches to the frame and the axle on the driver side. From dead stop, floor it, bet the leafs warp into an 'S'.

And the pinion angle goes way up.

 

Well i tried to burn off the right tire today turning right and it got traction lost traction got traction for about 10 times real fast in about 20 feet then vibrated out of it....i feel like now the assend is hurt.never felt a car or truck take off like that when i floored it on a right hand turn.the vibration is definatly coming from assend though.its behind me.i looked up some used ones w 80k on em for about 500.

 

Definatly got rid of the 25 to 40 vibration on cruzing and decel.about 75% fixed

 

Ie there a fix for those springs?

 

Replace them.

Take back to the dealer tell them to put the old drive shaft back and refund your money and take it to driveline specialty shop.

 

I agree axle wrap is most likely to blame, for one reason or another..

 

I had same problem with my 09 Tacoma last year took it to dealer and found out it had a tsb on that vibration problem and toyota paid for whole new drive shaft

 

Well that did get rid of 30 to40 vibration

 

My driveshaft was replaced under warranty as well for the inner core being loose. They then replaced the transfer case mount under warranty. Didn't fix the vibrations. I put washers under the carrier bearing to make the truck drivable. My rear leaf springs were flat or negative and were unable to carry even a small load without squatting. I replace the front and rear suspension with 2018 3rd gen Off Road suspension and the vibration isn't gone but it is much better and the truck rides way better!

 

Im convinced after 2 months of trying to fix this since i bought the truck....and $1500 in the last 2 months....and got 1 payment made that these tacomas are peices of shit.ill never buy one again and will be trading this pos as soon as i can...SHOULDA BOUGHT A CHEVY!
