Howdy, i just bought an 86 4wdrive Jeep Comanche. it seems to be stuck in 4w drive its a stick shift although the 4w drive lever is in 2h not 4l N or 4h but my 4w drive light is on and it defenitly feels like its in 4w drive when taking sharp turns. I fear this may lead to harming the drive shaft if anyone knows what to do with this issue let me know thanks, SOV
