2. Inspect gear lubricant for metal particles (lubri-
cant will have a “metalflake” appearance). Pres-
ence of fine metal particles (resembling powder)
on the drain plug magnet indicates normal wear.
Metal chips on the magnet indicate the need for
gear housing disassembly and component in-
spection.
