I think if I were you I would crawl under there with a drill (wear safety glasses) and drill that hole out. The reason I say is because when he took the punch the metal bent inward before it broke, creating a lip that will retain water. Yes, it is better than no hole, but a nice clean hole will drain much better.

How else are they going to get you to buy another one. But if they have to give it to you for free they do not want you back. Also, lifetime warranties are for your life, you usually cannot reassign it to the next user.

They had one but if you don't get it hot enough ever to evaporate all the moisture it will rot out. That was back before SS exhaust. We are talking the 70's and living in a large city, not to date my self but you just cannot help getting old.

terrible2 Actually just yesterday I moved my car about 10 ft and I parked. I saw fluid leaking down from my skidplate underneath my T-case. At first I was like oh crap, but it smelled like nothing and had the viscosity of water so im guessing it was just condensation.

That is correct. You get it because you are doing a lot of short trips and the condensation accumulates in the muffler. If you do a lot of long trips like I do in my daily commute you never see any because the exhaust gets very hot and evaporates all of it.

Weep hole in muffler? 2006 LJ -42,000 mi.

I just noticed some water dripping off the back of my skid plate. After further investigation - it was coming from what appears to be a weep hole in the bottom of the front of the muffler. It's dripping off the bottom of the muffler on to the back of the skid plate and on to the floor. I had just started the Jeep & backed it out of the garage to get the SAT radio activated. I pulled it back into the garage and noticed the dripping. I have not had the Jeep in any water. Is this weep hole supposed to be there or is this something the PO may have drilled to avoid water/moisture accumulation in the muffler? I know this used to be a trick in "the good old days" to drain excess moisture from muffler to avoid rust. In Penna., it's illegal to drill any holes in a muffler. What do you guys think? Thanks, Smitty
