Being 6 months old says that someone probably also looked at and probably repacked the wheel bearings. If the E-Z Lube function was used, there may have been a seal failure and one or more brakes are contaminated. This is especially true if those bearings were repacked using a full pressure grease gun instead of a hand operated lever gun. Many, not all of us don't use those E-Z Lube axle zerks, preferring hand packing instead
Too high controller setting will quite possible lock up the tires, leaving long skid marks along with flat spotting the tires. You may notice jerking at low speeds while at highway speeds - skid marks and a blue cloud of tire smoke
