My 4wd has stopped working and I'm not sure why. I checked all the gears and they are all in perfect condition. When I click the solenoid the light on the dashboard says 4WD is in, but the front tires don't spin. 4WD LOW even switches the gears into low, but again the front wheels don't spin. I don't even know where to start. Any suggestions?

 

sounds like your actuator for the front hubs took a crap on you...the actuator is usually on the top of the front diff its an easy part to replace and relativly cheap

First, we need to know what year vehicle he has to know if he even HAS an actuator, so what year is the truck OP? year make model etc...

 

maybe someone swapped you out for 2wd *gasp* haha jk.

give us some more info!!!

 

Its a 97 mazda b4000. Everything is stock, the gears/front end has not yet been touched.

 

his truck is truck is TTB, with automatic locking front hubs, sounds like one of the hubs is bad, being that the front diff is open, if one hub is bad, there will be no power transmitted to the ground. is the front driveshaft turning when it is in 4x4? check that first.

also, rangers never had the actuator on the front axle, that is explorer stuff. SLA rangers either have pulse vacuum hubs or liveaxle, neither of which apply to the OP

 

The front driveshaft spins, so I'm guessing I need new hubs? And If I'm doing that I might as well go to manual locking ones. Does anyone have any suggestions?

 

AVM, warn, or Rugged ridge for manual lockers. or go to the junkyard and get an older stock set...

 

It does sound like the hubs though? I wasn't sure if the hubs could be the only thing wrong because the drive shaft is definitely spinning.

 

yea it means your t-case is providing power to the front diff but that power has no way of reaching the wheels because youve got a bad hub

 

I found the warn standard manual hub kit. Are there any other parts that I would need to buy to convert from auto locking to these manual locking hubs?

 

conversion kit

 

and possibly different wheels
