94 Explorer 4X4

i just purchased a 94 explorer with automatic hubs and 4 wheel drive will not engage. I just put new rotors on and noticed that there is no o-ring on the outer hub. Is that normal for this year or could that be my problem? What is the best way to diagnose this problem? Any help would be greatly appreciated.

If you push the 4 wheel drive button, and the light does not come on, and the 4 wheel drive doesnt engage, it could be your 4 wheel drive shift solenoid. If you look up reliablility ratings for that year on your Explorer, this is a common problem. I had mine go out on my 93 Ford Ranger, and I believe its the same one on yours. I had to go through a Ford dealer to buy mine, and it cost me around $270 plus tax. It is relatively easy to put on, and its located underneath your vehicle near your transfer case. If this IS the problem, and Im only guessing that it is, you will need to call several different Ford dealers for quotes. Ford dealers all have different prices for their parts. You could also check with a salvage yard, to see if they have a used one.

Good Luck,
JB

Power transfer is really quite simple on these. Shift motor puts t-case in 4H -- t-case spins front driveshaft -- driveshaft spins differential guts -- differential spins axleshaft(s) (it's an open differential, so it may only spin one axle shaft at at time) -- spinning axleshaft causes hub to engage so the axle can spin the tire. Where in that power flow is the power getting lost? Is the transfer case spinning the driveshaft? Do the axleshafts spin with the driveshaft? Do the wheels spin with the axleshafts?

And note, waro, that your '97 with control trac is a little different. As for where the shift motor is, it should be attached to the transfer case.
