no way bro. if that is so you will feel more thumps. and it would fall out most likely.. (think about it) like 1k pounds + hangin loosly to mounts. dont even bother checkin

 

i just had this same problem after replace the engine. it starts to shake realy bad sometimes when i put in first and start to run it shaes little bit and then almost every time above 45 . the strange thing is that if i pushed the cluth stops doing it. i was thinking that the clutch was defective i removed the trans again and bought a new stage 3 xtd clutch and new flywheel disc and wow when finish you're not gonna believe after almost 6 hours of work and time to get the flywheel and all that. the car was exactly the same or worst. so my option were now limited. i changed the front struts and tie rod ends nothing helps. guess what was? the inner cv joint on the pass side. it looked good.it was replaced 6 months ago and never make any noise on the curves. so i'll check that first. if you got them on warranty now is the time to go and exchange them. mine had play from inside to outside try to remove the rim and raise the car, now turn the disc and check for any noise on the cv joint at the same time turn the disc as if you were turning on the street..grab the boot and feel any diference between right an left. irecommend you thatyou buy the complete axle on auto zone for around 80 bucks and now you got lifetime warranty. end of the story. hope this help you to fix your babe.
