I too have this same issue! I Disconnected the Drive shaft to see if i could narrow down the problem. my problem is in the axle assy. i check auto and manuel hubs to see if they are the problem. they are working correctly. i can turn the front drive shift by hand about 3/4 of a revolution before i get binding. i not sure if this truck has limit slip diff. Axle Code is C1. Also check the function of the Transfer case by switching 4x4 High and then back to 2WD. With truck off the ground. Front axle driveshift is engaging and Disengaging with proper setting. any info would be nice. Is this normal.
My truck is 95% Stock. it has never had any really front end work. my issue is with the front end off the ground. Wheels straight. turning drive shaft by hand. i have transmission issues also. I have isolated it to the front axle . but i tested the auto hub lock they are working.
I took apart the front right hub assembly, found that the Axle shaft was damaged and the bearing was damaged. have the right axle assembly out and i still have binding at the drive shaft. any one have any idea.
