High pitched hum coming from rear end
Ill be going down the freeway from 50-65 mph let off the gas then lightly press on the gas and it makes a high pitched hum, let off the gas and the hum stops so on and so forth. I had my mechanic take a look, the u-joint was good just out of curiosity. Put some diff additive in it and if my service records are right it was changed in the passed two years
