I have a 95 4.9. i noticed lately that it was shaking a little bit more then usual. I looked under the truck and saw the driver side motor mount nut was missing. I went to lowes and bought a replacement nut. i bought 1/2 and 12mm just in case it was metric i wouldn't have to go back. Does anyone know the right size? Also do I have to jack up the engine. When it got loose it moved up a little. Can i just put the nut back on it without moving it or should i move it back down where it was. Any help would be greatly appreciated. Thanks

 

You should update your signature so everyone knows what years and model truck you have. The answer isn't going to be the same for every year.
