My clutch is engaging fine the center diff is turning fine. Dogbones goint to front and rear are turning fine. Rear wheels barely rotate front wheel don't rotate at all. This is all off the ground. What are my possible problems? Just changed diff oi. Did the front no probs, center no probs ran her no probs. Did the rear a day later ran her in the morning ran with no problems. Went to run her in the evening I got nothing. even if I rotate the center diff with my fingers no front movement rear barely moves.
