well guy either way im 2nd owner, bought the car with less than 40k it was 70k the diff fluid has been changed exactly three times now and the tranny twice. now as for the oil probably 10x. so sorry if i mislead anyone

 

lol look under the rear of your car... if you see a big ol leak from a rubber bushing in your subframe...nissans going to tell you 1100+ dollars for new subframe...and your best bet is solid bushing for a fraction of the cost, its a bs install and process....but it has to happen eventually. remove your sixth cyclinder coil pack, theres 1 10mm bolt holding it on and a delphi connection, remove them and check inside the spark plug tube for oil its a known issue, do you understand now?

 

Why so much on the diff. and tranny fluids??

 

For the plugs, the book says change it at 105,000 miles.

 

The book says so, but you'll probably want to change them closer to every 60k miles. 75k is around the time most people swap them out.
