So i went to two different lexus dealers and they both told me the sound i was hearing are from the tires, they said they're cupped. So since the tires are expensive and I am not really bothered by the noise I will leave it be.

 

Well,at least you found out what it was.

 

Cupped tires are usually a sign of a shock/strut problem. Still something amiss.

 

Yes i forgot about that, damn.... i wonder what that will cost me, all four struts.

 

You should be able to get away doing the rears. Struts should cost about $200 for the pair & 3 hours of your time if you're a DIYer. It's not too difficult.

 

Called the service advisor back yesterday and she said my struts are fine the tire itself is bad.

 

Alllllllll-Ritey then......

 

cupped tires can produce the "whoosh-whooosh" kind of sound. I had all four of my tires cupped, albeit on a different car and, incidentally, they were bridgestone summer performance tires. replaced them with all-season Yokohama and I was a happy camper from then onwards...

 

also, drove for about 5-6k miles on the cupped tires with no ill effect on the suspension.

 

noise coming from above back driver side, the roof rack was positioned into the grove and still rattling noise coming from same spot. Any help ?

 

No, no rattling noise just the whirring noise. Talked to the service advisor again at the lexus dealer and he said that a couple other rx owners with the same tires have come in and complained about the same issue, sounds like a defect in these Bridgestone Dueler tires. Firestone says its the suspension and dealer says its the tires.

Wouldn't a blown or leaking strut would change the ride quality? I also did the push down on the car and see if the car bounce back up or not test and bounces up nice and slowly like it should. Any one else having same issue?

 

I find my noise.
Both rear bearing. $ 370 cnd each. Why both ?
The wheel have a 1/4 inch of slack on each side.
Rx330 2004
I buy the rx used.
120 000km = 75 000 miles

Nobody find a recal for these bearing of st

 

I took my 2010 RX 350 with 28000 miles in due to noise I thought was from rear tires, Yep rear wheel bearing needs replacment. Same time I felt the front end had a "clunker" type sound when going over rough road. That was due to a universal joint that needs replacment. Not a happy gal today. All covered by warranty but at 28000 miles, not a good thing. Listen to your wife....we have good hearing.

 

I just replaced both rear wheel bearings on my 2004 RX330. One bearing assembly was actually wobbling the other was worn and making a lot of noise at speed. All noises are now gone.
