GMC C60 Recalls

The GMC C60 has 3 recalls covering the 1976 and 1978 model years, with the most serious affecting 1978 trucks equipped with hydraulic brakes, gasoline engines, and firefighting equipment, where exhaust heat from the right side manifold can damage the front brake hose and cause a loss of braking at that wheel. The 1976 model year has two recalls. On the steering side, the nuts securing the steering gear and power steering cylinder bracket to the frame can have internal metal flaws that cause them to split, which risks the steering components working loose from the frame. The other 1976 recall affects trucks with Detroit Diesel Allison four-cylinder engines, where the accelerator cross shaft support bracket can be installed backward, creating a bind in the throttle linkage that slows the throttle's return to idle after the driver releases the pedal.
