It's pretty easy to remove the vent hose from the axle ... a pair of pliers to move the clamp and some tugging to pull the hose. Then clean the end off and blow into the hose ... yes, I know it's dirty, but your spare tire cover logo suggests you'll do okay ... if the resistance is low, venting is not the problem.

PS ... the hose goes up to the bottom of the body and is clamped there. Take a look to see if you want to pull it down or remove the hose at the axle.

:CWL: LMAO... that gave me a chuckle...

I have the TeraFlex ST2 lift and it included the rear trackbar relocation bracket. IMO it looks like the leak is your pinion seal. If you are planning on larger tires and re-gearing the differential, that would be a good time to have this seal checked and replaced. A great local shop for that is G-Force Off-Road in Orange.

If they installed the rear track bar relocation bracket, it should look like this on your Jeep (rear driver's side):

Looking at the height of the track bar in your photo below (how close it is to your axle compared to the photo above), my guess is that whomever installed your lift did not install the rear track bar relocation bracket which would explain why your axle is shifted to one side:

If that is the kit (link above) that you paid for, unfortunately it does not look like that is what they installed. Above I mentioned the missing trackbar relocation bracket but from looking at your other photos, that lift in the link also comes with new, longer coil springs and what they have installed on yours is a coil spacer with the original coil springs. If you are certain that you paid for the lift in the link above, DM me and I can look at your Jeep in person and let you know what else they substituted or didn't install (I'm in Corona as well).
