When disconnecting any of the steering shaft components, it is essential to reinstall them in the same orientation to maintain synchronization with other components. Park the vehicle with the wheels pointing straight ahead and disconnect the cable from the negative terminal of the battery. Use one of the methods to prevent the steering wheel from turning. Working under the hood, mark the relationship of the upper intermediate shaft to the lower intermediate shaft, then remove the fasteners securing the lower intermediate shaft to the upper intermediate shaft. Next, mark the relationship of the intermediate shaft to the steering column shaft and remove the pinch bolt, ensuring to match mark the shafts. The lower intermediate shaft and the intermediate shaft coupler will be removed from the steering gear as an assembly, but they can be separated and replaced individually if necessary. Mark the relationship between the lower intermediate shaft and the steering gear pinion shaft, then slide the lower portion of the intermediate shaft downwards and off the upper intermediate shaft, removing the lower intermediate shaft and steering shaft coupler from the steering gear. The upper intermediate shaft can also be removed from the shaft coming from the steering column if needed. Installation is the reverse of removal, ensuring to align the matchmarks and tighten the coupler bolt/nut and the shaft-to-steering gear pinch bolt to the specified torque settings.
