No big deal on replacing both rears?...

Easily replaced?...

Any tricks in unscrewing, I guess...

Just plug and play?...

Replacement brands...Bosch - Walker - Thoughts on best for replacing...

Thanks......

Just done this myself.First things first, buy original Nissan sensors to be on the safe side and avoid issues other forum members have had with other makes.Secondly, ask a friend to give you a hand feeding the new sensors down from above, and thirdly, I hope you have long fingers as some of the clips are a real beetch to get Out/in (getting them out just use brute force as the new sensors come with all the necessary clips).Time taken: about an hour to do both! Money saved: probably about 200 dollars compared to taking it to a dealership!
