Ok my xj has been sitting lately due to a couple issues but I have driven up to the store a mile away twice in the last few days. I have noticed the rear differential vent that plugs into the unibody, is blowing out a odd amount of fluid. Never seen this before. It's not dripping out of the unibody but u can definitely see where a larger than normal amount of fluid is venting. Not sure what to make of this. Dana 35 LSD rear end. Factory 3.55 gears. I'll include a pic. Any thoughts would be helpful. Need to know if I have something else to add to the broke list lol

 

Have you changed the fluid lately? If you have it might be over full.

 

Nope haven't changed it recently

 

You stated that it had been sitting for some time, if you've had hot and cold cycles it could be moisture escaping when the differential warms up.

 

Yea that was my initial thought to. Just thought it was weird that their was so much. I wanted to make sure it didn't sound like a bigger problem. Think I'm gonna change the fluid out this week just to be sure
