Whenever one of my back wheels goes up on a curb or for any reason is higher/lower than the other rear wheel, radiator fan rubs on it's plasic housing. So I figure that the engine is moving because of a broken engine mount? Or loose engine mount? How much does a broken engine mount cost to fix (ballpark) Or is this something that I could possibly do myself? Thanks guys for the help.

 

I did mine on my 4.9L and it was prety simple. It was over a year ago so I can't remember exact price but I want to say the mounts were like $30ish.

 

check the cross members of the frame. Maybe one is loose or busted. good luck

 

anyone else got ideas? What am I going to be looking for when under the truck, can you give me ideas?

 

get a jack with a piece of wood on it or something that would act as a coushin(so?) and jack up the engine and see if it does go up, if it does then see where it lifts up at and that should solve your problem.

 

good thinking, I should have thought of that
