Sorry to hijack, meshmesh, but I asked this a while ago and no one responded.
Do you have to use a different oil in the transfer case, because I intended to use Redline Lighweight Shockproof (Blue) in:
*Gearbox
*Front Diff
*Rear Diff
*Transfer case
in my 32GTR... or should I use heavyweight shockproof in the rear diff?
