2025 Chevrolet Suburban Service and Repair Manual

A mid-cycle refresh makes the 2025 Suburban easy to spot, with new front styling and lighting, and inside a 17.7-inch touchscreen now standard with an 11-inch driver display. The rear suspension was revised for ride and handling, and the 3.0L Duramax inline-six moves to the more powerful LZ0 design alongside the 5.3L and 6.2L V8s. Trims run LS, LT, RST, Z71, Premier and High Country. Those changes touch the diesel fuel system, the suspension and the infotainment wiring, which is why this factory service and repair manual is matched to the 2025 refresh, with procedures, torque values, wiring diagrams and diagnostics.

Known issues on the 2025 Suburban. One recall is on federal record: on vehicles with 24-inch wheels, incorrect bolts may have been fitted to the front wheel hubs, and they can loosen or deform over time and risk loss of control. No owner complaints are recorded. Wheel hub removal, installation and bolt torque specifications are all given in the suspension section of this manual.
