I have a 2007 Nissan Frontier 6 cyl. 4.0. I am approaching 200,000 miles and I am having no problems. I have done nothing to this vehicle except replace a wheel bearing and change the oil. What should I do to this vehicle as far as maintenance is considered?
Continue doing what you are doing. You may also want to service the differentials, 4wd, transmission. Also, if you haven't tuned it up, it may be a good idea to do it now. Replace the fuel filter, and check your owner's manual to make sure there is no scheduled maintenance on the timing chain.
