Seeing some rust and corrosion on my 2015

Hey Tacoma World. Wanted to get some opinions of what you think of these pics. I’ll be heading to the dealership sometime next week but maybe could get some insight here first.

These are shots up under the drivers side front. Just noticed JT recently and it wasn’t there over the summer when I installed my lift. I live in the Dallas/Fort Worth area so no salty roads or oceans near by.

Any thoughts on this?

Here is the passenger side for reference. Nothing at all.

Thanks for any opinions. 2015 DCSB AT TRDOR for reference too.

 

That looks like battery leak corrosion to me.

 

I think you’re correct. Right after I posted this I went and popped the hood...sure enough you can see it where it’s ran down. I replace the batter about 4 months ago. Two year old battery went and completely died on me. Wonder if it dripped from the old battery since the new battery looks completely dry.

 

Wash it off, hit it with a wire brush and shoot some black Rustoleum on it. The high performance stuff holds up pretty well. I do mine about once a year.

 

Make a solution of baking soda and water and rinse everything you can down with it, If you have to remove the battery to do it right then do so. Let it sit for awhile, then rinse off well and let dry. After letting it dry completely, then paint. Painting over remaining acid just lets it continue to do it's dirty work. The acid has to be neutralized. Make sure you wash inside the frame and I'd use something like LPS3 or Fluid film to get inside the frame and seal it.

 

I’d use some rust converter before painting it.

 

This.
Pull your battery out, and get at the battery tray (and under it) with the baking soda/water mixture. It will be fine once you neutralize the acid and coat the bare metal.

 

I had a battery that had a crack at the post that you couldn't see. On rough roads that crack would open up and run acid down, resulting in the problem you have. Look your battery over carefully. As others mentioned, you have to neutralize the acid with baking soda. It will take several treatments. The battery pan may have visible acid on it. This is not an uncommon problem, particularly on 4x4 vehicles driven on rough roads.
