Is this anything to worry about

Just noticed this, not leaking any gear oil but looks concerning. Anyone seen the rear axel/diff do this?

 

Did you drive through any puddles or pay the extra $2 for an underbody flush?

 

No

 

Checking your diff oil level will remove all guesswork.

 

What year is your Tacoma? Post #1931 has the weeping rear end TSB for 2016 and 2017 Tacomas.

What's the front of the diff look like? Where the ring and pinion bolt to the housing.

 

Also, check the breather. If it is clogged, pressure could be building up.

Twist and jiggle breathers. Ideally on both diffs. Top left of the diff in photo. looks a bit dry and corroded/dirty. If it's little cap isn't all loose and jiggly, spray it or take it off carefully and soak it in something like transmission fluid, oil etc. Heat causes pressure in diff which makes it seep. Breather vent lets this pressure vent out.
