Definitely a good idea... the "B" maintenance schedule suggests changing
axle fluids every 12K miles, (I do it about once a year, which works out
about the same as the schedule recommends!) :-)

I'm sure that the Mobil 1 is great stuff, but since you have the
Sure-Grip, you definitely need to add the friction control additive,
(Mopar Hypoid Gear Oil Additive Friction Modifier) whenever you change
rear axle fluid. Someone posted the P/N once, but I don't have it handy.
Apparently, if it doesn't get added, your Sure Grip clutches will
eventually fail.

Hmmm, I've spoken to several people about changing the manual trans fluid
on my Dak, and they've all said that it isn't necessary. The owner's
manual also doesn't have any recommended interval for changing the fluid
either, guess it's kind of like brake fluid, you don't usually change it
unless you have to! I had wondered somewhat about this, so if there's a
reason I *should* be changing it, please let me know!
