Known issues on the 1982 C20. Two recalls sit on the federal record. One is a driveline failure: rear axle shafts that were improperly heat-treated during manufacture can break, and a broken shaft can let the wheel and tire come away from the truck. The other covers a replacement oil filter that can seal inadequately, lose engine oil and start a fire. A single owner complaint, on seat belts, is all else that has been raised. Axle shaft, bearing and retainer procedures with their torque values, and the belt anchorage specifications, are given here in full.
THE REAR AXLE SHAFTS RECEIVED IMPROPER HEAT TREATMENT DURING MANUFACTURE. THE SHAFT MAY BREAK AND THE TIRE AND WHEEL ASSEMBLY COULD DISENGAGE FROM THE VEHICLE.
DEALER WILL REPLACE BOTH REAR AXLE SHAFT ASSEMBLIES, IF NECESSARY, FREE OF CHARGE.
THE DRIVER'S LAP/SHOULDER SEAT BELT RELEASE LATCH SPRING BROKE WHICH MAKES THE SEAT BELT INOPERATIVE. PLEASE EXPLAIN. *AK
