    I finally went fourwheeling today w/ my truck w/ its new 38s, i never got stuck, it was crazy, these things have so much bite and traction. any i noticed when i got home that i forgot to hook up the diff vent xtension lines and i was going through small rivers/ponds etc... wat should i do? Also, im running one open pipe exhaust, pass side only has header, and i have a dinky air filter, and everytime i would hit some decent water my engine would bog down, wats going on and how can i prevent this from happenning the future?

    thanks,

    For the diff hose. Pop the cover and drain and refill the diff. Next, get an exhaust system that exits as high as possible. For the air cleaner. Try to inclose it and get the intake pipe as high as possible or get a snorkle kit. Last try and make you ignition as water resistent as possible. How I don't no, but other here will.

    Hossbaby's got it. When I had to drain the water out of my front diff, I put diesel in a poison sprayer (weed killer, etc.) and used that to flush out all the "chocolate milk". Get a factory breather and snorkel with an opening in the core support. For most reasonable water crossings that will keep the breather dry and avoid hydro lock. If you want to get totally crazy, you'll need the after market (or custom) snorkel way up high. There are quite a few ways to make the ignition system relatively water tight. I'll let the mud boggers and people with more water experience than I have answer that. Mostly I just kept good, molded boot plugs and sprayed out the distributor cap with WD40 when it started acting up. Once upon a time, I even used silicone to seal up the cap, but that was too much PIA. Oh, and you gotta get a pipe on that open header. Otherwise your gonna have some serious problems.

    Rubber hose from Pep Girls, Autozone, etc. will work great when replacing or extending differential vent hoses. Very inexpensive too! Usually only about 15 cents per foot.

    Also, you could run you vent hoses inside the cab so it is alot less likely that get water in them again. You can do that with all you vent hoses. Heck for that matter, I've heard of people that run there air intake into the cab to prevent water inhalation. Thats only for when you are wheelin, not for normal driving. Also you could rig up some sort of splash gaurd around your vital ignition parts to help prevent water exposure.

    Are your diff vent supposed to be plugged? Because mine have white plugs in them and i never really understood what the vents were for.

    They should have little "loose cap" type affairs on them. The caps are supposed to keep larger junk and splashed water out. Lots of people switch to cheap in-line fuel filters (like VW) for better protection. Or you can run them all (2xdiff+tranny) up into the filtered section of your breather.They should have little "loose cap" type affairs on them.
