4wd Won't DisEngage

s10blazerman4x4 · #1 02-26-2005, 05:09 PM

Ok here is the problem. My dads 91 Explorer will not disengage. Sounds like a baseball card in spokes, he says. He tried to go in reverse for awhile but it won't kick out. Looked through the Chiltons manual but no avail and looked through here but only found maybe it could be the automatic hubs. Any info or suggestions maybe a 4wd switch on the console needs to be replaced or something else.

sounds to me like its the hubs. The grinding and nasty noises that they like to make. LOL Anyway, to disengage them, put in the 4x4 then take it out and back up for like 15 or so feet and that should do the trick to at least get you through the rest of the winter. I prefer my parents Blazer 4x4 system over my Explorers. Has a much better way of doing things. Good Luck with it.

My dad said the 4low came on by itself and wont go out. He pulled all the circuits and the battery cable and did some more reversing to no effect. If you hit the button on the console you hear a whirring a noise. Like its trying to go in but i dont know

4 low came on by itself?? Hmm.. usually just 4 high will do that when the hubs go bad. You have to put it in neutral to take it out of 4 low.

He told me he tried neutral for the 4Low. He said it does not matter it wont come out for anything.

man that sucks. Tell him not to drive it like that. You can't even go above like 30 mph. Could be that the shift motor is sticking. Go underneath and on the transfer case, there is a wiper motor looking case that is a cylinder shape with some wire connected to it. Try giving it a few whacks with a rubber mallet and it might loosen up a seized brush or something. That could be your whole problem. Let us know how it turns out. Good Luck

Yeah I had fun in that Nor'easter with my broken 4x4- got home just in time. It sucks living in Delaware in the winter

I had fun this morning went to move my blazer back on the street turned around got hung up on snow and ice ended up in a fence and shrub had to have my uncle pull me out with his jeep. My dad said he knows what your talking about did not climb under yet.

Cool- let us know how it turns out so anyone else with the problem can try to solve it.

s10blazerman4x4 · #13 03-01-2005, 07:44 PM
