will poly body mounts expand? what happend was i installed new set of b-mounts 2 years ago and torqued them down wrong did one side at a time vs. a star pattern so my passanger side is squashed down pretty good (over laps the bottom washer) and drivers side looks normal. so one day i removed the passanger side and took them out held in my hand didn't go back to shape, so i reinstalled. but will they go back to shape after like a couple of hours? The reason i ask is becasue after i had my steering brace welded on i get a popping noise under the passanger side floor. (near the body mount) and it pops loud enough that people turn around an look when in a parking lot parking. U-bolts could be loose also, causing the sound.
