Drove it to get close to the 500 mile mark for the new rear end.
Then changed the gear oil and put a new diff cover on.
Had to knock a bit off the cover to clear the gas tank skidplate.
Replaced the six 153,891 mile fuel injectors with new Morpar's (single jet). Also installed the Design Engineering Fuel Rail and Injector Cover Kit. Jeep seems to run a bit smoother but nothing to crow about. Still looking to narrow down the cause of a slight #1 cylinder miss. Cleared the P301 fault awhile ago and didn't come back but can still feel the cylinder miss. New spark plugs, O2 sensors and injectors so far...
