2025 Sorento
Have a 2025 sorento LX with 67k, was getting an oil change and they checked the rear dif level, was barely to check hole, and was black.
Is this considere 'normal' or 'expected'
I did pull a camper (1500lb) every 2 weeks over the last 7 months which might have put more wear on it, specially in northern ontario.
Looking at the manual shows change at 117k.
