Are motor mounts that hard to replace? Better yet, are the motor mounts the metal 'dog bones' that hold the engine up from the frame? It sounds right..but I only ask cause on my old school Pontiac 6000 (granted it was an '87)? We replaced the '87's dog bones by just levering up the engine with a 4x4 block of wood to take the pressure off, and swapped em out.
Havn't looked at the blazer's recently, so I'm just curious (read 'most likely wrong')
