That is insanity! At those prices I cannot afford to just fire the parts cannon at this thing. If I need to spend $1,000 to fix this van I will, but I need to know for certain it's the mounts before I can justify spending $1,000 on 2 parts!
As for the repair itself, the front sounds like a PITA but doable. I've read a few threads that claim the aftermarket mounts don't last longer than a year, but all threads stating that are just referring to someone elses thread with no link. I have yet to find a thread that someone says they installed an aftermarket mount that failed. Also, I don't know if these vehicles with the failed aftermarket mounts have been muzzled or not? Do aftermarket mounts only fail on VCM enabled vans, or does this failure happen on muzzled vans as well?
