I just got done driving my 83 300 TDT to Alaska (beautiful drive!) from Florida. Anyways I just noticed a thunking sound coming from the drivers side rear wheel. The noise is rythmic with the speed of the car (slower, less thumping, faster more) I have aluminum rims and recent tires on it and it only seems to do it after going up and incline and stops after I come to stop only to reoccur after a few more miles. I have check the parking brake. Any ideas? Why would it happen only after an incline? Thanks in advance.
