Hi all,
I've recently replaced my exhaust manifold. A great thanks to all of you that assisted with advise and what more! It worked out great and I love the way my jeep sounds!
However, since after the repair I now sometime hear a klunky sound from the back. I am no native English speaker and surely 'klunky' is not a real word, but that's how it sounds. Right after the repair I first heard this but since I was carrying around most of my tools in the back for a while the sound was easily explained as tools bouncing up and down on the floor of the trunk. So I was not too worried. However when I took the tools out I still sometimes here it. It's new (I've not heard that before the repair), and fairly rare. It mostly occurs when I idle or accelerating on an incline (hill-up). But it is not very consistent.
My guess is that I maybe changed the alignment of the exhaust a little so that it hits the car, but then I would expect the sound to be coming from the front (pan). There seems enough clearance there though. In the rear I did not change anything, and the only thing I can come up with is the cat. But i don't know what sort of sound a failing cat makes. Can that be something like what I described? Or is the cat hitting the car somehow?
What do you think? How do I check/verify what's causing it?
Thanks
Tim
