Try no LSD additive...for the synthetics, they're really slippery to start with....so adding something to make them slippery-er, is typically overkill.
All the LSD addive is for, is to quiet noisy diffs, prevent diff chatter, etc..by making it less grabby.
Grabby is good, at least as far as trying to stay locked more...too grabby, so that it can't differentiate around curves, eats your tires, etc....is when you add the additive.
I've used synth diff juice all along, and NEVER added any additive...because I didn't need it....the diffs were quiet, no chatter, and the tires were lasting and lasting.
Damn, trout season is almost upon us....
Eh, this years so far, going to be tough to get in fishing...between the wife's stokes, brain seizures, and now maybe cancer, plus the USUAL crap going on...I'm about out of time for most stuff.
