N's and R62's for yrs with same design. Never seen the front ever have an issue. The back axle yes but never the front. Many yrs of mudbining and hard going too. Somebody must have hit something rough real bad with a full load on. That's only my opinion as maybe someone else can chime in if they had this happen but I have never seen it. I have been to many wreckers over the yrs and you can see what gives trouble lol and never seen this. Hydraulic components on Gleaners never seem to sell at wreckers either. Gear box on rotors run out of oil from not changing leaking seals is common and first thing to go, and unloading augers from their low design hitting carts in uneven land unloading on the go. Then rear axles shafts.
