My front differential blew out on my 4wd a little over a month ago. The mechanic turned it into a 2wd by taking out Im assuming axels or boots. (Not sure what they are called) Anyways. Since all that happened, my gas mileage went from roughly 250 down to 176. Ive already changed the spark plugs. Tire pressure is good, changed gas stations too. I even put some stuff called seafoam to help 'clean' it out. Its due for an oil change now, and needs an alignment. But would that really take that much gas mileage away? Never had this problem before.
