The transfer case wore a pine hole in the case from the oil pump spring lock not securing movement causing me to loose all oil from transfer case. This left me stranded when I could not shift into 4 wheel drive the could not get it to re- engage 2wheel drive. This could have possibly caused catastrophic loss of control had the transfer case locked up while driving at high speed on slick roads or if someone ran into me from sudden lock up of the drive train.
