I have a black wrangler sport 2010 and i had the first pain in the rear water leak drivers side which took manytrips to the dealership to get resolved but its did.
Today with the mild weather its time to un-winterize the jeep vac it and get it ready for summer
So i opened the trunk it smelled badly a recognizable rot smell and the jack area in the trunbk had 1 inch of brown water ,the jack soaked and all the mexico vinyl sleeves that
hold the jack parts soaked and smelling.
In fact the whole trunk area had condensation(had a 400watt inverter in there that was dripping .
So i'm saying have a look in your trunk area ,its a spot one doesn't open a lot maybe you'll find what i found.
No real damage but it will have to dry out ,the mexican sleeves might be shot

 

I have the exact same leak in my 08 Wrangler X. I noticed it during winter. the carpet was wet on the passenger side near the gate and the subwoofer. So i dried the carpet figuring it was a small leak, but then when vacuuming last weekend I looked in the jack compartment and water and rusty jack just like you described. So I took out the jack and the parts bag and thoroughly cleaned all then pulled the rubber drain plug in the bottom to empty the water and dried everything back up. I also sprayed the area and all the jack parts with Nut-Z Lube. That stuff works great at stopping corrosion.
Definitely should keep a close watch after rain storms to see if the gate leaks. I haven't seen any water back there yet. So i think it was melting snow.

 

So do u guys know where the leak was coming from? I have a 2012, is this a problem on all jeeps or just the older ones?

 

It's more a hit and miss. My 2010 had no leaks and my 2011 doesn't have any leaks (knock on wood). However, that doesn't mean leaks won't develop (weather stripping will age). I don't think it's because it's a Jeep, but more has to do with it being a convertible.

 

Is there a weatherstrip kit for the roof and doors, just in case.

 

I will keep looking for the source of the leak, but it must have been small, and i don't think it was coming from the hard top.

 

They keep our water leak company Leak Pro very busy at work. We have quite a few bulletins on the Wrangler for water leaks. If your out of warranty look him up. Hes mobile and very good.

 

I had the same problem I went to Canadian Tire bought 2 cans to coat bed liners sprayed the truck and jack area no more water.Also I did the front floors no more water nice and dry and cheap to do.Best time to do this is the summer because the Jeep will smeel for about a week.By the way this stuff will dry really fast you can use the Jeep the next day.

 

Have any pictures of your interior? There has been lots of talk of this spray in liner as of late. I am interested in doing this to our jeep. Thanks.

 

Sorry no pictures take the time and remove the carpet and spray the floor this will work the next day put the carpet back in if you like.Looks the same as a pick up bed,
