well, my roomate mentioned water in the diff. does this look deep enough to worry about changing the fluid? oh and if you notice, i just had everything colormatched too( mirrors, handles, front valance, and rear bumper plastics)
Did he notice water IN the diff or water surounding the diff making him believe water will be in the diff? I changed mine after being held hostage in a river by sand and a log for 10 minutes and it was near my rear end. Depends on how long the diff was under water too.
he really has no idea if there is water in it, he just mentioned that the vent may have been under water, but didnt actually know how high the vent was. i only sat in that water long enough to take a pic, but i was driving through water up to the body line... maybe ill just change it for good measure.
Your vents are at or above frame level. That's the only way for water to get in. Like said, pull the plugs and check for chocolate milk. Chocolate milk = water in diff. If it looks like regular oil, you're fine. 95% you didn't get any water in there based on the pics.
ITC is correct. The only other way for water to enter is through the axle seals if they are damaged.. Usually the vent hose will have a valve on it only allowing vapors to run out. This is effective in keeping water out.
