    I would say a bad CV will not cause this all my cvs are torn and i have no problem with 4x4. I have never heard of a problem like this before.

    check your fuses/4wd relay/box? had a friend who bought a 4x4 4runner. the guy he bought it from said the 4wd didnt work. got to looking around and found out the fuse was blown. worked like a charm ever since.

    maybe the wire is unplugged from the switch behind the dash?

    I cant remember how 4 wheel drive is driven on the 98 but I beleive there is an actuator on the front axle .The front axle Could be vacuum controlled or could be electrical ...dont remember
    When you select 4 wheel drive on the transfer case , 12 volts is applied the the actuator on the front differential to move a shift fork to the 4 wheel drive position .
    Once the shift fork on the front axle locks into the 4 wheel drive position , the light will illuminate .
    Using a test light , Test for 12 volts at the front differential actuator when you shift the transfer case into 4x4 .
    A torn cv boot will not cause you to lose 4x4

    Hey , no problem . Thats why I am here ...:)

    So was the front differential actuator the problem ?
    Did you have 12 volts at the wiring harness at the front actuator harness or is this vaccuum controlled ?

    I have more diagnostics for you if need be . Let me know
