does the engine/box need supporting to remove the bottom lower engine mount ? https://www.google.co.uk/search?q=m..._AUICygD&biw=375&bih=591#imgrc=9WQzWiy8f0qUyM:
I always find replacing it with an uprated mount is the way to go, either the vibra one or inserts, vast improvement.
Depends if you have a black rubber coated older mount and can use inserts or if you have a cast mount in which case you need to press out the old rubber bit to fit the replacement. From memory I think you number is for the replacement and newer cast mount.
I've got the newer mount brand new sitting in the boot of the car typical lol I bet that's the more expensive one to get the poly bushes for
