Diff Question, please help. Hey everyone. Just recently purchased a 97' 318ti. I've had the car for about a month about put about 2000 miles on it. Its mostly free way driving, not a lot of stop and go traffic. Up until a few days ago everything was going smoothly until I started to get this loud howl from what im suspecting is the differential. It only starts to get noticable when I go above 40mph but gets really loud when I get up to about 80mph. Any advice would be great. Thanks so much. |
