Noise / Vibration from rear drivetrain
 

[X(]I have a 2004 Pacifica AWD with 74,000 miles. I have noted a recent shudder and noise coming from the right rear wheel. It is not a tire noise. I think it may be a bad wheel hub assy or rear transfer case. I lifted the car and spun the right rear wheel and the wheel had a thumping noise. The left wheel had the same but not as loud.Is this normal when you spin the wheel or does it sound like the bearingis going in the hub assy? I hope it is not the transfer case assy! Thanks!!

It sounds like a bearing to me. Have you ever changed the fluid in the differential? I would do that and have the bearings checked. It's not unheard of to have your bearings go at that mileage.

Thanks for the response!! Yes, I've had the differential fluid changed. Ialso checked the differential fluidlevel and it was fine. I agree with you that it sounds more like a bearing problem. It sounds like it is coming from the passenger side rear.

Possibly Not drive train... or bearing
