Thanks. Front, plug, yes.
( OldNavy, that's OK).
So why do you think the front comes stock with a drain plug
and not the back?
Do you think it's better to remove the front diff cover to
get it cleaned out better?
(BTW, I'm still not convinced that the diff OCI has to be as
often as DC schedules it, but you know, warranty.....).
Plan on putting in AMSOIL, and I wonder if JJ will then recommend
that I can extend the OCI and still be warranty compliant.
I don't see a problem using Amsoil Severe Gear and extending the service interval, however only your dealer can tell you Their stance on that situation. I do know that Amsoil would fight any claims by a dealer that a failure was caused by an Amsoil product and extended service interval. Amsoil has Never lost a fight about their products or suggested extended service intervals.
Considering the minor cost to DIY, I would suggest following the MFG's service interval (for the front diff) until out of warranty for peace of mind.
LMK if you have any other questions.
