Orangetang Posted September 24, 2007 Share Posted September 24, 2007 I must have accidentally pulled the front diff breather hose off when I did my engine swap, and not noticed. Driving through a river a few weeks ago was probably when this happened. I drained my diff fluid today with the suspicion that I had water in it.... I've been out of town for a week and a bit and last night it was making some whining sounds in 4High... Anyway, I drained it today and sure enough the oil contaminated. It had the clarity of chocolate milk, but was a bit thicker and still had the orange color and smell of gear oil. I refilled it with Petro Canada Traxon E 75w90 synthetic gear oil, the stuff we have at work in a 205L drum. 4High/Low still has a whine that wasn't around before. What do you figure has given in it, or might the gears just have worn a little..... Is there anything I should do further? I'll probably drain it again and refill in a couple of days to make sure all the water is out. Link to comment Share on other sites More sharing options...
tmorgan4 Posted September 24, 2007 Share Posted September 24, 2007 Sounds like you need to stay away from water with your luck!!! I really can't comment on what to expect for the damage but you can imagine what rust can do with all the moving parts. There's a chance that a layer of rust could have built up on the R&P which would make the gear mesh tighter and contribute to the whining. It's really hard to say without having a look at it, but with as easy as it is to pull the front diff (especially considering you've already pulled the engine) that's what I would do.

I'll take a look when I get the chance. Thanks! On the note of water and how to wreck equipment... Did you ever catch my post of my friends SKi-Doo sinking in a pond? The pond was less than Km from where I hydro-locked and bent my front crossmember and less than 2Km from where I drowned the diff. Maybe just that area is rough on equipment in general Link to comment Share on other sites More sharing options...
