"Dad I didn't do anything!!" The front transfer case was replaced as the original was split open. Engaging four wheel drive results in a flashing 4HI or 4 LOW indicator light. I jacked the truck up completely off the ground and ran it in four wheel drive. The front wheels were motionless despite the front driveshaft turning. I can get a used front axle for $200.00 at a local recycler. I just have to determine geat ratio. I will disassemble the original before I purchase a replacement to see if it would be cheaper to repair. It looks pretty straight forward. Can I just unbolt the axle from the frame, disconnect a couple plugs, remove the front driveshaft and CV joints?? Any advice?? Thanks!!
