So after installing the new motor mounts and removing the spacers from my Transmission bracket I started noticing a vibrating sound coming from somewhere when I was idling in drive.
I crawled under the XJ, had the wife put it in drive to figure it out.
Turns out the rivets that hold the exhaust pipe bracket in place had all worn and stretched to the point that the exhaust was vibrating against the Transmission brace.
I tack welded two corners in place after using a jack to push the exhaust back up. No more vibrations and I am pretty sure the jack-hammering when offroading was from the same thing. I guess I'll find out.
trying to weld it in place was a real PITA. I couldnt do proper surface prep because there was no way to grind paint and dirt out so I cleaned it as much as I could and put in my welds. Thanks to the confined space I managed to flash myself three times and get slag burns on my arm when a dingleberry dropped down my sleeve. :gee:
hopefully the welds hold, I'll find out during hunting season.
