Re: LSD Additives...Where to find?
perhaps because the Mobil 1 has LSD already in it, as far as I know, and mopar fluid (and some others) doesn't....you could also be on the threshhold of needing additional; who knows...Whatever the thoughts are on the subject, the fact is a limited slip differential needs some sort of additive beyond 'gear oil'. if it's blended, well it still contains it...
Also, being there's mechanical action occurring and each assembly wears differently (too many variables of factors such as temperature extremes, movement speed/alignment, etc.), the amount of additive could also vary down the road (beyond what is contained premixed)...
I would bet if you put mopar gear oil alone or another fluid that does not contain the additive, you would get chatter.
Not here to argue this, just if somebody changes their diff oil then gets some chatter/rubbing feeling on turns, chances are there is not sufficient LSD additive (or the right kind) , they'll now more than likely know what is causing it.
