Ok so i cleaned(?) out my 2 new diffs and loaded them with some 125k fluid. im not getting the locking action i was expecting, i know theres a fair amount in there because my on road turning radius sucks now lol, but if i get one in the air it just spins away and i loose momentum while trying to crawl. Im willing to try again, what is the best way to get the gears clean so that my 125k isn't getting diluted by whatever 30k is left in there.
Or should i be looking higher than 125k?
