If the car has been in an accident which resulted in frame damage, major body damage or in which the steering column was impacted. the column could be damaged or misaligned and should be checked by a qualified mechanic. If disassembly of the column is necessary. The steering column is installed by reversing the sequence of the removal operation, with the following note: when reattaching the shift indicator cable clip to the shift bowl, place the shift lever in the 'Neutral' position, then position the clip on the edge of the bowl so that the shift indicator pointer is pointing to the 'N'.
