1995 P30 Differential Problems; Large Shavings

I have seen when a bearing goes bad, the material coming off of them look like small pieces of aluminum foil, Thin sheetlike chips... If that is what they look like they could be from a bearing... Check your pinion for looseness by gripping the driveshaft where it meets the pinion yoke and try shaking it around.. If there is any movement of the pinion where it comes out of the case then it could be the pinion bearing..
