Clunk From Front while Driving in Rain

[Byrds8]

So it is pouring here today. It dropped a lot of water pretty fast so there was standing water on the roads. Nothing crazy mind you just puddles etc. However, there seemed to be a clunk about four different times. It seemed like it was coming from the front. Never felt the truck or any other vehicle I have owned do this. Is the truck doing something it should or shouldn't be? Thanks

Could be auto 4wd engaging?

It isn't on auto. Do these trucks have a real finicky traction control or anything? It almost felt like hitting a pothole. That is about the closest thing I can think of to describe the quick clunk. Granted it wasn't damage on the road that was causing it.

I hate to say this, but I had the same issue right before my lifters went out.

Wouldnt think this was coming from the engine. It has only happened when it was a downpour. The engine itself sounds and runs fine. Not to mention I have a Pulsar on it so DFM never turns on.

The sensors are detecting lower traction and or control concerns from the water puddles and driving to fast for conditions?  I get occasionally something similar in winter with low traction conditions and its usually because I am driving a little to fast.  One wheel speed changes so computer applies brake to other wheel to slow it down and catch up,  that's the clunking you hear, off/on application of (anti-lock) brake.  The computer has the ability to apply brake to just one wheel if it thinks it needed.   Just some of the idiosyncrasies of these safety systems.

Well, at least now I know its normal. You'd have to wonder how we all grew up without these nannies lol. I think I can live without a few myself.
