Just bought a new 2009 Titan SE 4X4 and following is my note (paraphrased) to the store manager. Do any of you with 'rattling' seats have this particular problem?
It seems that no matter which tire is on which wheel put where on the truck, and with force balancing, there is an extremely annoying oscillatory vibration in the front passenger seat at 68-70 mph. This is the same thing the manager at Goodyear Tires told me after 4 hours of switching wheels/tires/balancing and test driving when I took it there as a result of your service department telling me to. This visit, your service department replaced my wheels/tires with 4 off of another new truck on your lot and it still did the same thing upon test driving. They also checked the alignment front/rear and it is on, and I asked them to check the rear diff for shavings and the runout trueness of the drive shaft, which they did, and the rear oil was thick and black, but no shavings, and the drive shaft was within tolerances. They replaced the right front seat, which was rattling during the vibration, and that solved the rattling, but not the vibration; in fact, the vibration seems to be more prominent now that the seat is better anchored. The vibration prevents me from driving in this speed range, and it occurs upon accel or decel through this range, and is still prevelant and can be felt when my wife is sitting in the seat. As I told service, the seat vibration is a symptom of a problem that I am concerned will manifest itself much later in a failure(s), hopefully not a life threatening one.
