Awhile back after heavy rain on not familar street at edge town, at nite, I drove thru water go across road, it not real deep but hit it at 25 an not see till on it, if did go over center hub on wheel on colorado 4-4, for cpl seconds, not sure, could that lil water got past seals on hubs?

Only if the seals weren't sealed....

Yes , water is thin it can go where oil cant.

I wouldn't sweat it myself, but it'd be cheap to drain the oil and replace it for peace of mind. Water should be at the bottom if there's any in there.

They wouldn't get any wetter than driving in a rain storm. You worry too much Dave.

It should be OK. But you could drain the oil and put fresh in so you sleep better @ night.

X100

Yep..I could be wrong..If I'm not mistaken there is a vent on the transfer case that is open to atmosphere..If the vent goes underwater then the transfer case can have water intrusion..If the transfer case oil is milky then you need to change it..If it's true about the vent

For sure the truck is ruined.Ill give ya $100 for it.

The transfer case is up pretty high, it was supposed to Been changed once, like $50 plus bucks for less 2 qts lube, I not worried about it, just heard a squeaking noise 3 times in last week when back up an then nomore, thinking noise from drums with brake adjust when back up or maybe u joint noise, dry ? I had u joint another pickup make noise when back up slow, but sound different, it was deep as seen it in daytime another time after happen, an everyone was go though water in 1 side road, slow, I hit it at deep side at nite an at least 25 mph, an kept straight though it, scared me, if slower speed, it might floated to other side road, not see it till just bfore happen an not think bad

Sometimes if you are low on blinker fluid it will do that. Muffler bearings went out one time and made a similar noise as well.

Coonman 220, are you a descendant of YODA.
Funny you talk

Clean them off with a bucket full of sailboat fuel, that’ll get the water out.

You might be able to get it at your local hardware store

just take your shop vac and suck the water outta the tailpipe.

I'll bet you are overdue for changing those fluids anyway. Do it now. If you have water in there and leave it, you will not like what that water will do to your bearings and gears.

Hate it when that happens.

And while your changing fluids , change the fluid in your reverse bulbs.
That's where the noise is coming from when you back up.
You can thank me later lol

Ya, I don't think that problem nomore , drive thru water once. I just notice the noise of the first move of the day. When back up onto street from driveway. An hit brakes gone, try drive quiet parklot an not hear it agsin, it was loud just earlier. There other times when back up after sit awhile only, but hit brake pedal, nomore noise agsin until shut off sit awhile an back up , it could not hardly be rear brake shoe lining wore down bad, if front. Wear indicater. It do it all time ? Or more. Then what i mention. It been dry out an 1 job is gravel dusty parklot I park in, but no gravel roads other there, could dust got in drums an make noise when back up if rear brakes adjusting when back up ? I believe they adjust when back up

I think you're obsessing , Coon man. I still like you.

Only if you stopped to wet a line
