Rear end drain plug

AJs busted.

I was thinking more along the lines of those evacuators typically available to us "back-yarders" with the teensy little hoses designed to pass through the dipstick tubes. You know the ones that seem to take forever to do their job. Well they will hardly pass hot gearoil through them , never mind the filings that typically accumulate in the rears. And the plastic type hose is too stiff to really get down into the bottom where the gunk accumulates.
Now, the drainplug, at the bottom, will freely pass the hot oil and any filings that are in suspension. Much better idea, IMHO. My housing has been set-up to do just that. And if I see a tooth-chip come out, Im tearing it apart. In bygone years it was common for me to swap out diffs at the drop of a hat. I was playing. At one time I had pretty much every ratio, most SureGripped, TracLocked, or spooled, on stand-by ready to go, from 2.76 to 5.13. I got to be pretty good at swapping those.
