rhino front diff noises
Hi, I'm looking at repairing a rhino 660 YXR660FAT. I don't know its age but around 5 years old. When you jack up the front and spin the right wheel it is very notchy and rough. The left wheel spins freely. This is in 2WD drive. The 4WD drive button and diff lock button both engage (motor whirrs and drive engages or locks). Is this noise or roughness on the right hand side normal or a fault? The roughness seems to be in the diff as I have taken the right driveshaft out and checked the wheel bearing. Any help would be appreciated. I'm new to the forum and live in England so the english isn't very american if you're struggling to understand my writing. Thanks.
