they just called and asked if they could deliver it after their driver gets back from lunch - replaced front pinion shaft/ring gear matched set, set gear lash, replaced drive shaft, replaced two deck pulleys and brackets that were bent by driveshaft coming off, replaced engine oil/filter ( i had purchased that when new and sent with driver/hauler ) for its first oil change. They didn't charge me for the oil/filter change ;-) they also changed the oil in the front diff obviously since they had to tear it down. No noises observed, no whines, no clunks, no grinds, no squeals, diagnosis seems to be same that the ujoint either failed or not installed right and came apart resulting in the shaft coming loose from the rear drive shaft. The splines were not damaged to any degree on the transmission shaft and the new driveshaft slid on fine so it did not need replaced. I will watch for any leaks/noises.
It sounds like they took good care of you... and makes you wonder how it would have turned out had you gone in there all pi**ed off, ranting and raving the way that some of us might have done in our younger days.
Probably the repairs would have been the same... the difference is that you are welcome to return there.
It's good to hear that things have worked the way you would expect from a John Deere product.
