lexus189

thank you all for your reply to my problem, my car has only done just over 91,000miles, i have been to a gearbox guy and he says its not the gearbox, the noise is more of a humming noise which haapens at 40-70, it happens on 60 mph then stops then 70 then it goes quite. when you take your foot of the gas after 80 when the speed goes down, it make a noise at 70 then quite, the 60 then after quite,

Not that i know, i know that i've had the car over 1year 1/2 and i haven't done it, and not sure if the people before me have done that, i will try this hoping it will do the trick. If this doesn't work what else could it be !!!!

I have a Rx400h, when i am driving at 40-60 mph i get this whining noise from the front off the car, but it goes away after that, the noise is really loud at 60mph, have been to lexus and they said it might be the gearbox/tranmission. I have changed the tyres which are new, tracking is also done. Please could someone who has had this problem tell me what it is before i spend money i dont need too.
