Water Sound when braking/accelerating?

Hello All. I am brand new to the board and just wanna say looking forward to receiving advice and connecting with other Tacoma owners. I just recently purchased an 09 Prerunner and have been hearing water sloshing sounds when I brake and accelerate. I have Raptor step bars on the truck and read in another forum that there could possibly be water in there? I've looked but appears there is no way to drain them? Any advice would be greatly appreciated!

The holes under the rubber mounts on top have water around them but they are so small I just don't see how to go about draining.

 

There could be water in your frame as well. Did you go through water or mudding lately?

Oh and welcome to tw!

 

No I haven't gone through any water or mud lately. It's really baffling me that if it is the step bars that there is that much water in there! I'm not real sure what to do.

 

in my 09 I can here gas in the tank sloshing at stops sometimes give that a thought.

 

Have you checked your coolant level lately? Maybe hearing it sloshing around in your heater core.

 

does it sound like its coming from the inside or outside of the truck

 

If who ever made the sliders tried to weld them to make them sealed may have left a pinhole on the top. It does not take much of a hole for water to get in. Drill holes in bottom at front and rear.

 

Well, I've got it in my head that it's in the step bars, but it's definitely at the sides of the truck. It seems like its louder on the passenger side.

 

It could be a clogged evaporator core housing drain, they get clogged fairly often with leaves and gunk.

 

this^^^^^^^^^^^^^^^

 

Check the doors also by shaking the drains could be clogged

 

Get out of the truck. Grab the roof with both hands. Shake truck back and fourth.....listen

 

Happened to me too in my F250 years ago. Ended up I had water collecting under the carpet which collected in the double-walled cabin. Ended up being from a variety of sources to include poor draining around the door gaskets. Rain and going through automatic car washes/hand washing with a hose added to the problem. Not sure if that is your cause but worth taking a look at. As mentioned above, it could be the AC/evaporator too.

I ended up drilling a hole up from under the truck into the cabin and water came out like a waterfall. Later plugged it up with some RTV and a plastic plug. Replaced all the gaskets/weather stripping around the doors and it was solved.

Hope you figure it out as it's frustrating.

 

Just an update for everyone that took time to comment on the thread: I removed the bolts under the step bars on either side and about a 1/2 gallon of water poured out of each of them! Problem solved. Thanks to everyone who gave some insight into the water sound mystery. I think I will drill holes in bottom of each side bar now

 

That is cool glad you found the source

 

I had THE SAME issue. Thanks for pointing me in the right direction.

 

Same thing I just discovered after reading your reply. I had water in both of my raptor rails causing the water noise. Funny early in the mornings I could hear the ice in the water. Probably got a 1/2 gallon of water out of each side. Thanks
