I'm pretty sure the nv 245 in my quadra drive commander is shitting the bed keep getting service 4wd message and a bang that sound like the case on moderate hard acceleration from a stop or hard acceleration from slower speeds I also noticed today backing up over some snow covered boulders neither of my back tires were turning just the front so pretty sure clutch packs are shit ...anyway the used cases I'm seeing for sane have 20-40k more on them than the case I have which I'd rather not spend the time swapping just to do it again weeks later so looking to get a case that's rebuilt without having to pay $150-200 shipping
