What is estimated cost labor and materials to replace a motor mount on 95 Mercury Villager?

Depends upon which motor mount it is. I've replaced the lower rear mount on my wife's 96 LS and the part was about $75 and it took me about 2 hours. You have to raise the engine enough to take pressure off of the mount and then wiggle it out once the bolts are removed. I also paid CarMax $225 to replace the same mount on our previous Villager, a 93 GS (same mount). The more miles she piles up on the thing (183k and going strong), the more repairs I figure out that I can do and it's always cheaper than paying someone else. Time is an issue though. Andy
