Fall Maintenance Window for Your 2015-2020 GMC Yukon

The best month of the year to catch deferred work. Applied to a 2015-2020 Yukon, here is what that looks like.

Body and Exterior

Watch for a mirror that shakes at highway speed after a folding motor fails. Not a scheduled item. These are damage and failure replacements.

Suspension

Watch for a clunk over expansion joints that you feel in the floor more than you hear. Shocks and struts are wear items. Plan on inspection at 50,000 miles and replacement somewhere between 60,000 and 100,000 depending on road quality and load.

Sensors, Cameras and Driver Assistance

Watch for a backup camera image that flickers, goes blue, or shows lines. TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.

Drivetrain and Transfer Case

Watch for vibration that appears above 55 mph and grows with speed. Transfer case and differential fluid on a schedule that tightens sharply if you tow or run in dust. Wheel bearings are replaced on noise, not on mileage.

The Short Version

Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
Shocks: Trim and package content matters enormously here. Off-road packages, air ride and adaptive or magnetic damping all use different parts than the base vehicle wearing the same model name.
Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
Transfer case encoder motors: Ride height, axle ratio and locking differential content all change these numbers.
