4.5
Expensive, but required for the LSD rear in 2011+ Grand Cherokees. Saved about $150 doing it myself. FYI the front diff takes standard 75W90 synthetic gear lube and the transfer case takes synthetic ATF. Need 1.5quarts of this to do the rear diff. Pretty much every 5.7L 4x4 WK2 has the ZF built ELSD rear differential.
