Auto Locking Hubs
Can someone tell me if could be nessesary to have to "back up" some 40 feet to "unlock" the hubs on a 96?
We have a light clanking when normal 2WD driving. When we put it in 4WDH the clanking stops and all four wheels pull. When we push it out of 4WDH back into 2WD it remains quiet but the gas milage goes from bad to real bad. Not until we back up some 30-40 feet does the clanking and milage come back.
Didn't think with the later generation auto locking hubs that backing them up was required.
Where am I going wrong here?

RE: Auto Locking Hubs
There are no locking hubs.
It is a vacumn controled shift fork that locks the axle in on the pass side of the housing.
These can get moisture and corrode.
It wouldn't hurt to pull it off and check it out as well as the vacumn to it.
Not sure if they are still vac. operated or if they went to an electric solenoid to move the shift fork.
No you shouldn't need to back up to disengage the 4WD.

It's located on the backside of the front axle on the passenger side.
The unit may not be in perfect working order anymore...especially if the vehicle's 4wd hasn't been used frequently over the course of it's life.
It states in the owner's manual that you are supposed to put the vehicle into 4wd once a month and drive around on a surface that is not solid (gravel, grass, sand) to keep everything working properly.
