To remove the front drive shaft on a 4370 Massey Ferguson, you will need to access the drive shaft from both sides of the tractor. On the side opposite the front wheel, you will need to remove the drive shaft support bracket and loosen the U-bolts located on the axle housing. You will also need to disconnect the yoke from the differential and disconnect the yoke from the drive shaft. Once these steps are complete, you can then disconnect the drive shaft from the transmission and slide the drive shaft out of the tractor.
