I have a 90 Lumina with about 134,000 on it and the motor mount is shot along with the 2 dogbones. I can accually move the engine with 1 finger when I disconnect the bones!!! How hard is it to replace the lower mount underneigth the motor? Any Suggs?

 

Its not super hard but it is fun, I replaced one on a freinds car one time, we put a jack under the pan and removed the trough bolt , then jacked it up and removed the bolts into the block. I had to use a boxed wrench to get to them because of the cramped space. but If I remember right two came of by wratched with an extention. A way to help the new mount is to put a rad hose clamp around the thing tight to help keep it together.
Remember also to put a board under the pan to jack on, never jack on the pan without one.
