I want to change the driveshaft oil seals on the 3.27 pumpkin going into my 94 but im having a hell of a time 'trying' to get them out. They just do not budge! I've been messing with one of them just strying to pry it out with a large screw driver but it just breaks the rubber, but the entire seal is still there and does not seem to move. Any suggestions? DO i need a special tool? Thanx!
