Fluid Advice - 98 GC Diffs
I have a '98 GC 5.9 Ltd and it's about time for a complete fluid change.
This is new toe me, so I have a question about what to put in the
differentials.
The owner's manual it refers to an additive if I have the limited slip. How
do I know what slip I have or were all the 5.9s the same?
And what additive aer they talking about?
Thanks in advance.

Re: Fluid Advice - 98 GC Diffs
The 5.9's all have the same aluminum Dana 44 with a limited slip, and a
pretty tight one too, judging by what my wife's 5.9 does to our curved
gravel driveway every time she drives on it. It makes more of a mess that my
detroit does, spitting gravel and digging trenches, even after 140000km of
use.
The additive is referred to as "friction modifier", and some will say that
any gear lube marked as suitable for limited slips has enough of this
modifier in it. Since a little bottle of the additive is pretty cheap at the
dealer and lasts for several diff lube changes, I've always added it anyway
so I don't know what the effects of not using any might be.

I understand that not using any wears out the clutch packs quickly.

Re: Fluid Advice - 98 GC Diffs
If so, that might explain why the clutch packs in my wife's 5.9 are
obviously not worn out - it's always had the Mopar additive used.
