Re: 4 wheel drive disengaging

hi everyone. i have an 07 ranger xp. the question i have is than when i'm drive down a snow covered or ice covered road i like to keep it in 4 wheel drive. at 30mph it disengages and the back tires will break free and start to slide all over the place. is this normal or is there something i can change to prevent it from happening?

The AWD system really is not MPH dependent but RPM dependent. If the engine RPM is over 3100 RPM and or traction is stabilized at the front and rear wheels the system will disengage and will not re-engage till the RPM is below 3100 RPM. It may work a little different on rangers without the ECM modules.  The RPM limit is a safety feature so you will not grenade the AWD system. There is no way to fix it unless the ECU is reprogrammed and i do not know anyone that can do that. Even if you can there is a big risk on the drive line :shock:  :idea:.
