98 Land Cruiser transfer case issues

[blbiggs]

has anyone experienced any trouble with the transfer case on the HF2A(i thing this is correct) in there 100 series cruiser? while driving down the road the other day it was like someone put a manual trans in neutral and was trying to force back into gear. From what ive read these things are basically bulletproof and never fail. I can put it in low range and it drives as normal. Engaging CDL in high makes no difference. Any help or suggestion would be appreciated. i have aprox 150k on the odometer. fluid is full. If you try to shift back in high range in any transmission all you get is high pitch grinding and no movement?
