My font pinion bearing in my front diff. froze up and when I activated my four wheel drive at 45 miles an hour the truck felt like the brakes were put on and I smelled clutches burning. I replaced the front diff. and now my transfer case will move the front wheels if the truck is on jacks,but on the ground it will not turn the front wheels. I heard that 4 low was a direct drive but it still will not spin the front wheels on the ground. I know that the clutches are bad, but could there be another problem. I'm sure I can rebuild it myself, but would it be worth it cost wise or should I buy a rebuilt one? Thanks Jeff Horton

Figure out which is best for your pocketbooks...
Switched selector on transfer case and acactuator on front axle. Took for drive and it still don't work. Any suggestions?
