: : My 1993 Suburban blows front differential fluid out of the blow-by line whenever I a drive @ 60 plus. Any ideas why?

: GM's IFS does not have axle hubs at the wheels, so the axles are always connected to the wheels.
: Since they are constantly connected, they churn the fluid constantly.
: Mine did this when new and after I flushed and replaced with Mobil 1 at 3,000 miles, it's not done it again.
: Stuff looked like cream colored latex paint. Someone mentioned that water mixed with lub fluid looks like this. Was worried, but since I have over 78K miles with no problems, I'm less worried...knock on wood!
: My vent hose is up there by the window washer fill neck so it's easy to see the stuff when it blew out. If it does it again, I'd extend the hose and run it higher & back down.
: Mine is 4.11:1 ratio. What's your's? Maybe it has something to do with the rpms/ratio.
