Drive Train
AN INOPERATIVE PUMP CAN CAUSE INCREASED STEERING EFFORT, AND IN HYDRO-BOOST EQUIPPED VEHICLES ALSO INCREASED BRAKING EFFORT, BUT DOES NOT COMPLETELY ELIMINATE THE ABILITY TO STEER OR SLOW THE VEHICLE.
The hydraulic pump that controls power steering and in some cases hydro-boost power brakes may experience a fracture of its driveshaft. If this shaft breaks, power steering assist will cease immediately and hydro-boost brake power will also cease following depletion of stored reserve pressure. An increase in steering and brake effort may cause an accident. Dealers will replace the hydraulic pump.
