What is the thread size for the bolt going through the front motor mount? More specifically the nut at the end. I heard a noise coming from under the car and I noticed that the nut was missing, I must not have tightened it down when I changed my mounts out, thanks all

 

Bump, need to figure out what size this is asap!

 

Just go to Home Depot and get a new, thicker nut & bolt and replace the thin stock Mitsu nut & bolt combo.

 

Well what would be the optimum bolt size to get? Should I just support the motor with my jack and take the bolt in and get one thats a little bit larger and holds more torque than stock, or is there a size already posted somewhere else? Thanks for the reply

 

Just support the engine from under the pan, remove the through-bolt, and take it to a hardware store. Match the size and thread pitch with a new metric nut and bolt with a 10.9 strength rating.

 

Cool, thanks for the help fellas
