I bought a cat 980B last year and it has a bad sound/vibration when roading it. The guy before said it did it as long as he had it. But he never looked into it as he just kept it in the pit.
About half throttle in 3rd is when you really start to notice it. It does it in both 3rd and 4th. I haven't got it to full speed in 4th as it gets really bad the faster you go. It's like a whining/humming sound, and you can feel a vibration in the machine. The pitch changes as you let off and get on the throttle. It sounds like it's coming from underneath slightly behind the seat, but hard to tell.
I checked u-joints and they all seem to be good. I'm not sure where to look next. Any common things that might go on these loaders? I'm almost leaning towards the differential.
