Hi I just replaced my rear diff 2003 legacy l model 2.5l and I can drive a little way maybe 5 miles and feel of it and its too hot to touch it has fluid in it. by the way my last rear went out cause of overheating could it be a wheel bearing or something my wheels are not hot brakes and e brakes are not stuck this is my first Subaru and its not going so well hope I can fix this and my thoughts on this car Thanks in advance
