Over the years I have seen many people talk about just changing the drivers side mount , I decided to do both and am I glad I did because the passenger side has completely separated from the steel part of the mount and it did not show any excessive vibration in engine compartment ! And of chores when I tried to take the frame bolts out the first one broke off in the frame ! I noticed a slight bit of red loctite on the threads , so that meant it was time to hit each bolt head on the frame with a few seconds from the MIG , after that they came right out ! Now the one that broke off , it got the same treatment the broken off exhaust manifold bolts got , set a nut on the broken stud weld the inside of a nut hole closed , and it came right out , YA !!!
