(Perhaps interesting to note?)
Although the differential had done less than 2 km in total driving distance; after draining the oil in a clean bucket
There was immediately evidence of "bits" in the oil
This is what I found in a totally clean casing with new bearings (but used cogs).
It isn't what I was expecting to see after such a short distance. This could of course be a result of the dreaded tick but I get the feeling that "bits" are almost always going to be in a differential so don't worry too too much when you see them too!
