Last night I installed a crossmember from an AX15 to lower my tcase and the rear vibes are gone!!! Unfortunately I now have a growling/vibration in the front when I accelerate or rev the engine in park. Im not sure if this is related at all but as I was supporting the trans with a jack I hear a small pop so I lowered it back down a bit. I looked everything over including the pan and everything seemed fine, no leaks, no cracks, nothing out of the ordinary. From inside the Jeep it sounds like the exhaust might have moved or come part but from under the hood and under the truck it sounds ok. Im going to check the motor mounts tonight as it almost sounds like one could me bottomed out or something. Any recommendations would be appreciated.

I'd look over your exhaust system closely. Very possible something happened with it and it's causing it to come in contact with the crossmember or something

Thats true, it was raining this morning so I didnt get to look everything over very well.

ZINGGG

Well that's your best starting point. Look it over and let us know what you find

Yep its the exhaust, the new ax15 crossmember is pushing up on it pretty hard! Anyone ran into this????

Fixed...remove crossmember, talk to the exhaust with a little heat and a hammer and now have plenty of clearance.

I had to remove my crossmember as well....I need to shape it to make it work....

I just removed it to heat the exhaust, I didnt have to do anything to the crossmember.
