The technician will put the vehicle in neutral on the lift, rotate the wheels, and listen for any abnormal metal gear whine from inside the motor reducer, and check for gear oil leaks at the joints of the reducer housing.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

Definitely. Lifting the chassis is a mandatory part of our standards. The report will specifically show whether there are oil stains on the front and rear shock absorber cylinders, if the rubber boots of the lower control arm ball joints are torn, and if the steering tie rods are loose or deformed.
