Other question is ... i picked it up from the shop after the mechanic refilled my transfer case which is leaking because i need a new front seal which i am replaceing next week. He also replaced my clutch fan and flushed my radiator. well i drove it for about twenty miles at various speeds up t0 60 mph. i didnt think that something sounded right. so finally when i was leaving my ma's i noticed it was in four wheel drive. which the mechanic must have left it in. and now i still dont think that it sounds right. kind of like a roaring noise until i get going to about 20-30mph?
