So I have installed the poly trans mount on my 2010 370 about 4 times now and every time I get a binding noise coming from the drive shaft. I have sent picture and video to Z1 to diagnose the sounds but they haven't be very responsive (sound quality not that good either). That said I had a mechanic look at it with me and he definitely agrees there is noise coming from the ends of the driveline (mostly in the front). My question is, when all of you installed the poly mount did you experience the same sound. The first few time it actually made some popping and cracking noises as well, but this last time it just made the binding noise. It seem to me that the variance between the stock mount and the Z1 mount is causing undo wear on the u-joints, but without measuring the difference in the two after they have been installed its impossible to know, so I thought I would just ask all of you. I also got the poly motor mounts as well, haven't put them in yet.
