1998 GMC C1500 Suburban Service and Repair Manual
This factory service and repair manual for the 1998 GMC C1500 Suburban covers a four-door sport utility sold in Base, SLE and SLT trim, with the turbocharged 6.5L diesel V8 and the naturally aspirated 5.7L gasoline V8 as its two engines.

Known issues on the 1998 C1500 Suburban. One owner complaint is logged with NHTSA for this model year, and it concerns the service brakes. A single entry says little on its own, but brakes deserve attention on a vehicle of this weight, and the manual sets out pad and shoe inspection, hydraulic bleeding, rotor and drum specifications and the torque values for the hardware involved. The rest of the book covers both engines, the transmission and axles, steering and suspension, climate control and the electrical system.
