front diff. breather hose
Hey there 87black150! You may want to check the fluid level. It does spin pretty good in there and if it's too full, it could easily work it's way out.
Is the vent tube very long? Is the vent in the upright position? Is the assembly fastened to move with the suspension, or the frame? I've seen the syphon action of a vent tube pull the fluid from the housing when it's mounted to the frame.
You can pull the plug to check the level. It's in the front of the housing near the middle. Nothing should come out when you pull the plug. If it does, let it empty into an appropriate container, until it stops. Then you are at the right level.
If there really is no other way to fasten the vent to the suspension, you'll need to extend the hose a couple of feet. Make a loop with the tubing just before the vent and wire tie it together. Then mount the vent. The extra length, will keep it from pulling on the tubing when the suspension moves and the loop is to keep the syphonig in check. Get back to us with the results... Thanks....

Checked the fluid first thing, it's good shape. The vent hose is attached in the stock location, along the frame above the diff. I never noticed any fluid leakage before, until I forgot to unlock the hubs and drove about 10 miles. In those 10 miles it blew out enough fluid to need about a pint and covered the driver's side bottom of the truck all the way to the rear bumper.

OH! OK then, yes that would happen. I'm sorry, I thought it was a continuing problem. It has now stopped leaking?
If it has, and it lost a pint or so, I would check on it the next time you've got it in 4wd.
Having the hubs locked is done all the time in snowy conditions up here, without engaging the t-case, so it really shouldn't hurt your system at all.
If at most, all 4x4 vehicles, should lock their hubs, run a couple of miles, then engage the t-case for a few miles on a straight or semi-straight road. Just to keep them lubed and to check the over-all operation of the 4x4 system.
It's better to do it in nice weather, and if something is going on and you want to check it out, the weather is better now,in most areas, and you'll have a month or two to get it fixed before you really need it! Thanks for getting back to us. Talk to you later....
