Ended up having to do some deep water crossing last nite to get to a good fishing hole. I have a stock 98 Limited and the crossings were about 28 " deep. Brakes are dragging a bit today ...anything else I should look at or modify to do this again (other than a snorkel).

Cheers,
Heavy

My brakes have done that too. They do it all the time in the golf carts where i work if we hit a deep puddle or something - it has always gone away, not really sure what is causing it.

I would kinda like to know myself

The only things i can think of as i haven't crossed much water myself would be a lift, tires, and snorkel

how long and how deep and how hot wuz yer diff ?

the very best thing is to raise the 4runner
pop all 4 wheels and pop front disc calipers
and clean them out

rear, clean brakes, grease parking brake
pivot with high temp brake grease, and inspect differential to ensure
water did not get sucked into the diff.

also pop drums off and inspect axle seals make sure water didn't get in.


that is the full inspection, your mileage may vary


also your 02 sensor external elements....every time you bury them you
take life off them. so, one time... prob not a big deal... but if you wet them a lot
then life is reduced
-------

you really don't -have- to do anything, but if you want to keep the 4runner
and not mess with bad axle bearings or bad brakes you should get used to pulling
all wheels off every time you drown them. and regrease the rear.

!! extend your diff breathers up high if this is what you plan to do a lot of...4 bucks of rubber hose
will save thousands in gear work

A few bucks and 20 minutes of your time could mean a saved diff and less headaches in the future. I would drain your fluid (rear diff, at least) and replace.

lifter up, boy!

repack wheel bearings and regrease drivetrain, etc.

Then wouldn't it be a good preventative measure to find some boots for them and seal the boots or fill them with grease?

A lift won't fix the brake issue he's having guys. I've never run into what you're experiencing, stock or lifted. Definitely follow these guys and do the rear diff breather extension, WELL worth the time and effort. The front is already up in the engine bay I believe. Of course a lift won't fix your brake issue but will definitely help with clearance of stuff in the water plus it'll look dang fine up a bit!

see avatar... have done it many times....02 is stock original with over 255k, what you say makes sense, but I was clearly an exception.

you def wanna extend diff breathers, as well as your tranny and transfer breathers, I have filled my tranny with water a couple times (first time no breather extension, last time..guess my breather wasnt high enough) and its not pretty... takes alot of flushing!!

thanks for e feedback. can someone send me a link on extending the breather's...thx again

Search??? It isn't hard...


This is for an FJC but it transfers over well

This is good too

And then also check the Wiki!

no...I mean the little white circles. that is the external air inlet for
the ceramic element . you cannot cover them or block them.

the electrical connector is fine. it is designed to be mostly immune to water

what ages them is dirty water, and grease flung from yer
u-joints and propeller every time you service it.

dunking them just cuts the life down. usually they dry right up
but each time the ceramic element gets dirtier ....not a big deal
really but it will make them wear out faster

Sounds like everyone's got your bases covered...I'd check your diff fluid to be safe. The bogging of the brakes is probably from debris and mud..so give em a good cleaning and inspection.

they can be bought here if you dont want to source the parts yourself.

dont forget to run breathers for your tranny and Tcase, more important than diffs I think

on a newer vehicle i wouldnt worry too terribly much about damaging your O2 sensor due to repeated water crossings. Water in the exhaust could cause a strange reading but all newer O2 sensors sample air through the actually wiring itself, and not directly from the outside. As long as your O2 sensor wires are properly routed and not cut from the stock sheath the zirconium dioxide in that sensor shouldnt be exposed to water and the life wouldnt be effected.

now on an older vehicle with a one wire sensor that samples directly from the outside air next to the exhaust pipe you betcha it will kill your O2 in no time.

BigBallsMcFalls

wow, this is so incorrect on how o2 sensors operate



all o2 sensors sample outside air from one or more
of the inlets on the sensor itself. there is one element and
fresh air has to be exposed to one side of it while the other
side is exposed to hot exhaust and that is how you get a voltage
change

multiple wires are for the
heater circuit. single wire sensors had no heater circuit and
wouldn't operate until they got up to 600 deg from the exhaust
