hi all, im having a bit of a dilema, i stripped the car today and washed it with wasing up liquid and water, well that went well it dryed, i took the elecs and engine bare in mind, but i turned the rear hub carriers and they were tight i stripped that and air compressed the gunk out, then re assembled it, but still the same i stripped the diff and water came out is this the problem?

please look at the pics, there is loads of gunk in there aswell do i need to take it all apart then wash it then wait to add my new oil in thanks
