3 votes Currently voted the best answer Vote for this answer. Telescopic steering is a device used in GM cars specifically. Cadillac is the primary employer of such a device. Between the wheel and the dash on the steering column is found a metal tab that is the adjusting collar.This collar is attached to a threaded insert that when loosened screws out away from a metal rod that actuates the locking device. It is a fairly simple device. It is never found without the tilt steering option.adillac is the primary employer of such a device.
