I have a 2005 tundra SR5 2wd and makes a doodoodoo sound and was told the differential needs service. Should I take it to the dealership our do you think it wont be a dificult task for my friend who has mechanic skills to offer. Does it have to be toyota OEM parts?
if diff needs work, toyota dealers do not repair them, at least around me, they would just replace it or a LOT of money. Try to find a good tranny shop to see if they work on them
