Gas moving around in tank - feel thumps

Why does this gas sloshing around not happen in other trucks or vehicles? Any theories as to why it is so incredibly noticeable in the Tacoma? To the point where it thunks and resonates through the whole cab? Seems odd, I wouldn't think Toyota is making a gas tank too much different than any other manufacturer or even vehicle in their fleet.

 

Worse in the cold? Maybe slipjoint...

2-piece drive shafts will always have some sort of vibe; it's inherent to the design...having an odd number of u-joints.
IMO, addressing drive line angles before addressing axlewrap is futile.

 

It is gas moving in the tank when it's full. Tank baffles don't go all the way up. Once the level goes down, it stops doing it since the baffles keep the gas from slushing.

 

I hear it too. Its for sure gas in my truck. My 16 corolla does the same thing. Only when full.

 

Happens in my gen 2 as well. Pretty sure gas tank design is carry over despite what seat belt Mike says

 

Yup, OP here...it's definitely the gas. I think TacoMan got it right with the baffles not going all the way up. Backing into my garage with a full tank of gas always does it. Now that I know it's there, it annoys me. Hopefully I didn't ruin things for any of you that hasn't noticed prior to me saying something! lol

 

It’s def from the gas tank. At around 3/4 full you feel the fuel thump the gas tank at a stop. Not present on full or below half for me.

 

totally thought it was normal. my old Dakota did it, as did my Ram Charger.

 

Totally this, mine does it when it's almost full if you stop kind of abrupt

 

It’s fuel in the tank. Usually the worst at around 3/4 tank. At full it’s not as obvious around 1/2 it goes away because the baffles in the tank come into play. Mine does the same thing, it’s 100 percent fuel. Terrible baffling system in these Tacoma fuel tanks.

 

I lot of the fabricators are offering off road tank baffles these days. I had a titanium set made up and they are so sweet. Plug and play.
