Yea, the CV boots actually look really good. I changed the diffs with Royal Purple fluid and they claim you don't need friction modifiers with their product b/c it's already intergrated in. But regardless, I have not options on my WJ and have open diffs. I've also used this fluid the past 2 changes w/out issues.
But last night I sucked it up, got the power washer out, and crawled under the Jeep. I took it mudding this weekend and went places I shouldn't have. It had mud EVERYWHERE (including the bottom of the hood). I pressure washed all the mud off the bottom and around the driveshafts. Maybe I'm speaking prematurly, but I haven't heard the noise again. It could have been some loose mud clumps on the driveshaft. Crossing fingers that it was that.
