Fighting suburbia in NC
Member
Posting for a friend who has an older/early MF1260 MFWD that has developed a clunk that sounds like driveline wrap under load. Seems to be worse going uphill and is definitely front driveline as it disappears in 2WD. We got the front axle off the ground and I listened to all of the rotating assemblies with a stethoscope and could not hear anything that sounded "different" or like a brinnelled bearing or such. Of course the hours are unknown but the tractor is in overall pretty good shape for its age and everything seems reasonably tight.
What should we be looking for as a cause? I checked all of the knuckles and hubs and they seem to be good so I am leaning toward the front pinion being the source of the noise. How do these fixed geometry front drivelines come apart? Looks simple enough and seems to be pretty much identical to JD, Ford/NH, and Kubota's of that vintage and size so what goes south in these setups over time? Any words of wisdom much appreciated.
