I have a 1998 F-150 4.6L, auto trans, 4WD, with 140,000. The front axle would not engage, I checked the fuses,OK. Check the front axle, and noticed the soleinod or plunger would not move. The transfer case works OK and shifts into and out of low gear. Should I remove the this plunger unit and bench check? Is it 12V? Thank you, rnd.

The auto-engagement feature on these vehicles do fail. After spending 5 years in Montana with winter temps below -30F, If you ever go offroading and this failure occurs, you would dream of the ability to exit the vehicle, lock in manual hubs, and go on your merry way. I have done this conversion over 100 times. But if you just drive to church on Sundays, the autolock is a wonderful feature.
Don't get csught up to your axles in the woods or snow with a non-functioning 4X4.

Yes, I do go off road. It failed on a recent fishing trip in the High Sierra's. So, what is the conversion, appox. cost. I am in SoCal, we have 4 wheel drive parts stores. I use it in 4wd at least 3 times a month. Thanks, rnd.
