With 795 hours on my DK35 and no problems until I heard a snap in the tranny case and the 4 wheel drive is no longer working. My question is if the drive shaft to the front axle can be removed without removing the front axle? I am hoping it is just the coupler that joins the drive shaft to the spline shaft in the tranny. There was the loud snap, but there isn't any noise with the 4 wheel drive engaged or dis-engaged, I consider that a good sign.
