the2008 pilot that i own has a rotation sound that has been happening for a couple years now, it sounds like a high spot in the front driver side tires but have had tires replaced and both front wheel bearings, still the same, it gets louder the longer that i drive, the repair shop has test driven with me and agrees that there is something, he reccomended that i have a transmission place check it so i did and they agreed but when they raised it up on the lift with the engine running and in dve gear, there was nothing. it needs to be on its own weight, i'm afraid that something is going to let go when i have the kids in the truck doing 50 or 60 mph. I really want this solved, no one seems to know where its coming from or whats the cause
