This DIY is for the front motor mount . To remove and replace this motor mount you do not need a jack to hold the motor from tilting . You need to replace the splash guard from the bottom and do all the work from underneath the corolla . Basically three bolts holding this mount down . Once you remove the mount just replace it the same way you took it off . This is what it will look like when you are finished . For more info http://rinconrolla98.blogspot.com .
