January 20, 2005Well, they are vacuum actuated but apparently not out at the hubs. Are you having troubles with the hubs on the Ranger? I also have a '98 Ranger SCab 4x4 with no hub issues......yet!

October 17, 2005I thought I'd revive an older subject in hopes that it will enlighten someone else with a similar problem. I learned today that it is likely that many with a similar F150 4x4 will have the same problem if they don't already have the upgraded parts.
As it turns out, my issue described above all stemmed from a bad shifting fork in the front axle housing. My transfer case was fine as was the vacuum actuator that throws a little lever that enters the axle housing actuating the front axle. The shifting fork has two little nylon "tabs" that fit into a sleeve that floats on the axle. When actuated, the fork slides the sleeve over a couple of gears which engages the front wheels. The little nylon tabs simply failed and came apart so even though the vacuum system was working, the shifting fork was moving back and forth inside the housing but it was no longer connected to the sleeve so the front wheels did not actuate.
No broken axle. Just a $550 repair of which I'll out of pocket $200 for my $100 deductible and the $100 diagnostic which the warranty policy does not cover.
It's about time I got this handled!
October 17, 2005Yikes, my grandfathers '96 F350 had some sort of a nylon thing in his hubs or front end that went bad and he had to get them replaced. Makes you wonder who comes up with some of these ideas.
October 18, 2005Can you hear a clicking or rattling noise when taking off from a dead stop or when you're doing about 30mph? One of my hubs went out or wasn't sealing properly about 6 months ago and I kept hearing the noises described above.
October 18, 2005Nope, no noise whatsoever. Again, the problem is not with the hub itself. The problem is located just to the right of the front diff. There is a vacuum actuated lever visible on the backside of the axle housing. There is an aluminum fork (which will be steel now) just on the inside of that actuator. It is simply no longer engaging with the sleeve that should slide actuating the front end due to the nylon tabs being damaged. This part has been upgraded because of "piss poor design" I was told by my Ford mechanic friend. I could have run a 100,000 miles with no ill effect other than not having 4WD. On the other side of the coin, it could have failed while engaged and I would not have been able to disengage the front end.
