I have a '93 Rodeo, When i take it out of 4X4, It goes out fine, when i get upto 30mph, the left front auto hub starts grinding, as i slow to a stop, i get a couple good clunks, and then it seems released until i get back up to 30mpg, then it starts grinding again.
I took the hub off and degreesed and relubed the hub and it still does it. After i park it for a few minutes, its fine to drive in 2WD again.
Any ideas what i should look for, It almost seems like a valve isn't relieving the Vacume pressure, to release the hub. Or whatever makes it work.
Thanks in advance.
