    The only way to know for sure is to take off the diff cover and look...not too hard of a thing to do.

    and it is very important to keep the gear oil good in the 250SX's more so on the 85 but still on 86

    Sounds like the differential bearings failed and is or did cause the gears to go bad. If you need another differential let me know.
