ESOF issues

I know some of you will say to just dump it but that is not gonna happen so here it goes.

When I engage my 4X4 High it will stay engaged as long as I maintain momentum down the road but as soon as I let up on the throttle and slow down or stop at an intersection the front hubs disengage. If I switch back to 2wd and then back to 4X4 it will re-engage until I slow or stop again.

If I manually lock the hubs and then switch to 4X4 they will stay engaged.

Am I suffering a vacuum seal leak in the hubs or is there likely another issue? If it is a vacuum leak in the hubs what parts do I need?

Thanks guys.

Because were lazy and paid a nice premium to have this option. But on the serious note although my comment is true, I like this system and Warns are a great upgrade, I just like the fact that Jay and I don't have to get out of the truck. A bump and subscribing Jay, mine did something simular just last week.

See this maint LINK by Guzzle. Needle bearing lube but deals with ESOF vacuum leaks.

Jay I like my ESOF's also and plan on keeping them as long as I can. I did the Guzzle rebuild this spring I was also having some problems but after the rebuild they work like new. Also check all of your lines for cracks or splits.

OK that narrowed it down. Looks like the time to do the Guzzle Rebuild
Welcome to guzzle's 4x4 Autolock Hub Lubrication Maintenance Web Page it worked for me.

Thanks for the links guys. I did not even think of Guzzles sight. D'oh!

It is part laziness and part $$ on keeping the ESOF. At least for now. I think I know what my project will be at our MN G2G.
