Hello Everyone,
I own a new 2019 Lexus LX that can with every option under the sun. I have the Lexus original factory cross bars that make a lot of wind howling noise even at low speeds - like 50 mph. I moved the front cross bar further back hoping that will fix it. No dice. So I am looking at these spoiler like device made by Yakima or Thule but having an issue on how to fit it. Do I stick this between the rails - 45 inches apart or over the rails - 48 inches apart. Anyone done this and can provide a picture or more info? And lastly do you have any other solutions. Thanks in Advance.
I still have the cross bars howling even at 30 MPH.
I got up higher on the ladder and noted that the side rails have 3 sets of predrilled holes and my Cross Bars are installed in the front and rear holes. Anyone else have a solution before I make Lexus take these bars back. I cannot believe they would sell a vehicle with these on howling like that.

Correctly installed, they will NOT howl. Double check EVERYTHING in the procedure that @nayak1 posted.
Did you install the cross bars, did your dealer, or were they a port-added option?
Hello Gentlemen,
Nayak1 - Thank You for the instructions, I will check them to what’s currently installed.
Hankinid- I do not know if these were dealer or port installed. This vehicle was a dealer exchange. They were on the car and Listed on the car’s original window sticker. However I am going to make sure they are installed as per instructions.
When the cross bars were STD equipment the EPA fuel economy rating had to be
tested with them in place...all standard equipment, tire sizes etc. You have all noticed
that the bars are now an accessory and thus Not mounted when EPA tested.
Since the cross rails reduce MPG, cause wind noise even when optimally placed
and limit your ability to clean and dry the roof, why not just take them off until you
are moving Christmas trees?

Optimally placed, as you put it, will NOT cause wind noise. Nor do they limit your ability to clean and dry the roof.
I just had this same issue after taking mine off to wax the roof. Your rear bar is facing the wrong direction. The elongated (Swooping) part of the bar should be facing rearward for the back bar. The front swoops forward for the front bar. When I installed wrong I immediately noticed and it sounded like a window was open while driving. Below is a pic from the instructions - notice where the lock and direction of the elongated side.
OMG, Thank You - Even though my rear bar was correct, it was the front bar that was installed incorrectly. Naturally, I am disappointed that Lexus Techs could not follow simple instructions and though this car had been driven by the dealership manager, their solution was to take it off. NO more howling. I bought this vehicle in February with 600:miles and was a dealer swap with another Lexus dealer and this was the poorest dealer pre delivery prep I had ever experienced.
