okay, the "divide box" your talking about is called the "transfer case" in english. Considering my engine is 70hp and people have problems with their transmissions wearing out with that to tame, i'd say you may run into problems with that. Though from personal experience, if you change the gear oil when recommended and shift properly, your sentra will treat you well. My 4wd transfer case has NEVER had ANY problems in over 100,000 miles, and it shows no signs of giving up yet even though i use it regularly.
