Ken what are you asking? Has the rear end fallen out? Broke/won't go? Makes noise? Differential won't lock up? Or many other different possibilities. ....

Harvey yes the rearend spur gears ground up into a fine shavings along with the left rear axle spline.This has happened twice on my late 1999 JD4300.And this past weekend it broke again.Only difference is this time it was the rearend and the right axle. 1) was at 25 hrs. 2) was at 50 hrs. 3) at 120 hrs.First two times I was pushing Brush (limbs and small trees, from a past ice storm.This time I was digging a ditch with the backhoe and started to move the tractor forward and it snaped.Just wondering if others have had this happen.
