Are you real sure the gearbox is wiggling or is the play just out on the snapping roller. I had two this year that one had sheared off the gearbox shaft at the large roll pin hole. The other was slipping where four bolts clamp it to shaft and chattered out the roll pin hole. You have to turn it just so to see the shaft inside to determine which is moving when free playing it. I was told by dealer that just the nose pieces, the two snapping roller shafts, will come out without removing the gearbox. havent done it because I am outside and 4 inches of snow and below zero this morning. IF you have to take gear box off you have to pull shaft out on that side and unbolt. Not bad but hope you dont have to. Hope this helps in any small way. --don--
