Hey all! I own a 2004 Titan SE Off-Road with the Big Tow package. I absolutely love the truck, but the past couple weeks I have had this bizarre road noise. ANY thoughts would be great!
Here's what has happened so far:
1.) Bought the truck, and the dealer gave me a free extended warranty. (2004 but only has 58k)
2.) Started to get a rotational "Whoosh" sound that seemed to be in sync with the tires as they turn. Faster you go, the more "Whoosh" you hear
3.) Take it to Nissan they say drivers side rear axle seal is pouring fluid, and bearing is probably bad.
4.) They fix seal, and put a new bearing in. I pick up the truck noise is still there!
5.) They take the truck back and say it needs a new passenger side hub assembly and bearing. They replace at no cost, noise is still there.
6.) Now they think it could be the front differential. They replace the entire front differential, noise is still there!
7.) Last but not least they replace the drivers side hub assembly and bearing, noise is still there.
Interesting to note, if the truck is on a lift with someone in the cab pushing the gas in drive, there is no noise at all. The noise only occurs when the truck is actually on the ground driving.
To me, that says tires, but the noise sounds identical to a bad bearing, but we have eliminated that issue. The truck as 4 almost new Nitto Terra-Grapplers on it. (Maybe they have 5k on them tops?) I've read that a sidewall bulge, bad belt, etc. can cause some strange cyclic road noise, but I guess that could be a long shot.
I also thought a bad rotor, but when you hit the brake the noise stays exactly the same, and as I said up on the lift it makes no noise at all.
Furthermore, it's not so much a "scraping" sound as it is a vibration. You can really only hear it with the windows up and the radio off. Every rotation of the tires and you hear it.
I got the truck up to speed (60mph) and put it in neutral to let it coast...same noise, same frequency etc. The truck drives and shifts absolutely beautiful, and there isn't any jerking int he steering wheel under any conditions.
Sorry for the long winded post, but this really is bizarre! I know maybe a bad tire is a long shot, but I really wish I had 4 stock rimes\tires to test the theory. he truck is going back for a full day for them to look at this week. If they want to keep throwing parts into it at their cost, fine, but I would like to enjoy the truck at some point too.
Any ideas would be great. Thanks.
