Known issues on the 1988 S10 Blazer. Four recalls are on the federal record for this model year. The significant one is a steering defect: the intermediate shaft loosens at the coupling to the steering gear, the pinch bolt wears into the shaft splines, and the joint can eventually come apart and take steering control with it. The other three cover replacement lamps missing amber side reflectors. Thirty-nine complaints have been logged, led by service brakes with six, engine and cooling with five and body structure with four, all covered by this manual.
