I had my Rubicon Unlimited (6spd-man) for a month, and it was leaking oil from the rear main seal. Just had it replaced this week, but getting the new part was a challenge for the dealer, not sure why... I hope it is not a sign of things to come...

 

My Guess is all the parts are going to build more at the factory!

 

I had my read seal replaced about 2 months ago. It started leaking after I changed the oil. It took them 8 days to do it. But I have to say the free rental car helped out.

They also had to do the following:

1. replace the radio. The cd player stopped working.
2. I found out 2 days ago, the bolts on the sway bars were missing.

But I have to say, I'm still glad I purchased my X JK.
