Hello everyone, I have been replacing my stock fluids over the past few weeks in preparation for a 10k mile road trip this summer. Since Midas changed out my rear differential fluid two weeks ago I have been having a groaning or humming noise occurring during on-thottle sharp turns, where the car was previously silent.
I have been in contact with RP, whos customer service is awesome, and they told me to do some slow, tight figure 8s in a parking lot which I did (30 total). This oil also has 500miles on it already and is silent when going straight or turning without any throttle. I just ordered some Ford XL-3 fiction modifier and am going to try and add it at 1oz increments until the noise goes away.
My reason for posting is, has anyone else experienced this groaning humming noise since changing their rear gear oil? I have the stock 3.15 rear differential as well. On more than one occasion I have also had the inner wheel skip slightly during turns with a generous amount of throttle, while the outer wheel stays totally hooked with the pavement. Is this a bigger issue than gear oil?
