96 explorer disengages 4wh low but does not engage 2wheel

Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..

did you put the actuator in the transfercase or the front diff if you did not but a new one in the front diff remove it and check it most likely its the one in the front diff should be easy to get to and can be removed without loosing any fluid

The 4X4 on your vehicle is controlled by a electronic control module .
Service 4 wheel come on ? DTC'S - diagnostic trouble code's are stored in the transfercase control module . Your best bet ,take your vehicle to a qualified repair shop

2002ford explorer sport, the 4 wheel drive high or low

The transfer case may be hanging up, have you ever had it serviced with new fluid? If not do so and drive it for a few miles and try again, if that doesn't fix the issue you will need a shop to inspect the transfer case actuator motor and position contacts.

Need a seal that goes behind the transmission where the shaft goes i need the part number and where i can find it

this all depends on if the truck is a 4wheel drive, are you looking for the seal at the transfer case where driveshaft goes or seal on the back of tranny where shaft goes, i assume from what you said its 2wd and you want seal at rear of tranny where driveshaft goes, heres the seal # and napa auto parts has it or you can have another auto part store cross number to there seal, good day seal # ATP 14982 and heres a picture of it, this is for a 4.0 engine ,johnjohn2_122.jpg

Does the vehicle have to be in neutral when you put it in 4 wheel drive, or what is the proper way to engage the 4 wheel drive

it has to be running and in neutral to engauge the 4x4. shift to neutral,then push the 4x4 option that you want. 4wheel high you can use almost any sensible speed.4wheel low is only for low speed 15 to 20mph is best for 4wheel low,otherwise will damage engine or transfer case. when you take it out of 4x4 it has to be in neutral also. thank you for choosing

When 4wd is locked in it pops right out, then when you coast backwards it pops back in

well with what ive dealt with in the past on those is bad tranfercase control modules your symtoms sound exactly just that the controll mod cant determine wether its in gear or not theres is also a sensor located towards the top of the transfercase that tells the module when its fully in gear the first thing i do is to make sure the transfercase is in good working order by pulling off the shift motor and putting it in gear manully
