It is a direct replacement of the broken parts inside the steering column tilt and extension motors of my Nissan Murano 2009. It is alot easier and intuitive to replace the two motor units as a whole, but at a very high cost (close to $400 each), but well worth of extra time spent for the part replacement (say extra 1 hour to disassemble for the replacement). Time will tell the longevity of these parts, but they fit perfectly.
I had it installed by my mechanic on yesterday and it's working flawlessly. No longer is the steering wheel position too low. The instructions came with the parts and was spot on and easy to follow. Thank you, thank you, thank you. Would definitely recommend!
