My 07 Frontier started making the dreaded whining noise at 45,000 miles only when cold. I ran it by a dealership (South Charlotte Nissan) at that time, but they said they couldn't hear anything. As time went on it got a little worse, I could hear it all the time. At 56000 miles, last week, I took it to another dealership (Harrelson Nissan), they could hear it plain as day, but said they've heard worse. Service adviser agreed they needed to be replaced and would be able to do it next week. By the way, service adviser's name is Alfredo, shook my hand, actually got off his *** and came outside and listened to my truck, very professional fellow. I dropped my truck off this Monday at 8:00 AM and he called Tuesday at 1:45 PM to say it was done, they were pretty busy. Truck runs great, just like it did when it was new.
On an another note: I've run Mobile 1 or Pennzoil Platinum synthetic oil and a Wix filter since the truck had 1000 miles on it. People can stop posting questions on the synthetic verses conventional oil and how they affect timing guides. It doesn't matter, they are just gonna wear no matter what you run.
