i just replaced my front and side engine mount in my 2000 tl. my engine still sounds like it wants to explode when driving over 15mph, so bad i wont even drive it. i think i have to replace the rear mount i guess. just want to know for sure since they aren't cheap. my front mount was surely bad so im guessing the rear may be too. i have 236k on it and they never been changed. i guess my question to most is can the engine get super super super loud when these mounts are bad or is it just a little loud. if its just a little loud i may give in and take to mechanic but i still hopeful its the other two mounts. i know im rambling a bit but any help would be great. thanks
