Well, just bought a 2001 used Sportage. Love it so far even though having alarm problems and O2 sensor issues, but working on them, and getting great help from people here.

So, next problem. The 4x4 does not work. I read all the stuff I could find here. The hubs work fine and does not appear to be the problem.

Here go how I diagnosed it.

Scenario #1 Put in 4wd drive - light on, Jack up both front tires, I can spin the front tires by hand (bad)û the axel CV shaft also spins(appears hubs are locked)(good), the drive shaft does not spin (bad). I can not spin the drive shaft, it appears locked in the transfer case. It appears to be an issue in the differential case.

Scenario #2 take out of 4wd drive, spin tires, front axel does not spin (good), drive shaft does not spin (good), if I craw upper and spin the drive shaft by hand, the axel CV shafts do not (bad)

Scenario #3 jacked the back end off the ground, put in 4wd drive with only the front tires touching the ground, and nothing, no tracking, no engagement (bad).

Appears to be the front Differentialààanyone every here of thisàany ideas, any suggestions. Nothing is ever easy, I was all set even excited to buy some warn hubs to fix it, but unfortunately thatÆs not the problem. <img src="/forums/images/graemlins/barf.gif" alt="" />

Looking for your help.
