Hello, I own a 2000 Land Rover Discovery Series 2. my catalytic converter and the driveshaft are touching and rubbing against each other. I have replaced the engine mounts, muffler, and resonator pipe, with no change in the situation. just wondering if anyone knows what might be causing this?

 

Either your exhaust is bent, or your alignment is so far off it shifted your front axle all the way to one side.
To check the latter, look at your front end from at least 10 feet away and see if one tire is sticking out one side further than the other….you should hav an equal amount of tire on both sides sticking out.

 

Also, one last possibility, your exhaust hangers are broken or not attached…but it would have to be most of them for that to be the reason
