Today I dropped the cover off the rear end (mod. 70) on the '96 I recently bought, to change the oil to synthetic. The truck has 46K on the clock, but when I looked in the cover, the magnet had a lot of "fuzz" on it. I know this is ferrous debris, but the amount startled me. If the original owner never changed the oil in the rear end, would this be normal? The ring gear to this untrained eye, looked o. k. not scored or pitted etc. Cleaned out all the oil I could, then sealed it back up and shot the Redline to it. I used the 80-140W as I plan to pull a 5th wheel this spring. It also has the LS as most probably do.
Thanks
