I just bought my Titan LE last friday. I'm selling my 2k1 Durango tomorrow. I haven't had an ounce of trouble until tonight. When I turn sharp left or sharp right, I'm getting a sound from the rear end that sounds alot like the tires are rubbing against something. They aren't. Nothings loose and the tires feel solid. I don't have a torque wrench to check the lugnuts, but the wheel is really tight. I had the differential fluid changed to Amsoil Series 2k 75-90 about 8 months ago. Sometimes it's loud, others you can hear it at all. I have 40k on it. I stopped by a local shop and took 2 techs out for a spin and they had no idea what it could be and didn't want to comment without checking it out thoroughly. Any ideas on what it could be? Bearings maybe?
