Roof Rack Wind Noise
« on: January 27, 2013, 12:39:33 AM »
Gday All,

We recently had an ARB alloy roof rack fitted to our 200 series Landcruiser, full length with mesh floor and an awning off of the passenger side.
Wind noise is giving me the $hits and was thinking about a wind deflector to help minimise the noise.
Are they worth the money?
Any advice on reducing wind noise would be greatly appreciated.

 :cheers: Glenn

Hi Glenn,

From my experieces, a wind deflector does not reduce the noise at all.

Unless you have a real need for it to be there all the time, I would remove it until you are going camping etc, that way any noise will not annoy you!

p.s. Removing it will also help with fuel consumption.

Swogjb, I hear you (well, actually hear the noise from the rack first). Exactly the same for me, ARB 3/4 length steel rack with mesh floor fitted about 2 months ago. I think having a sunroof makes it even worse. Agree, needs to be removed between trips, but that's another 12 bolts to remove & reattach (so the channel covers can be put back) each time. Another PITA chore. Camping was supposed to be getting easier....
I reckon ARB's R&D section needs to work on this. Their sales blurb (propoganda) goes on about how their racks are the best etc but I bet a Tigerz or similar at half the price will make no more noise.

Too true :).

I have a wind deflector forum ARB rack and reckon it does help. I was going to re-fit it today in fact after getting it painted but its raining at last. Also, I fitted muddies and don't notice the rack all that much now.

You will get used to it.

I think the wind deflector does reduce wind noise, although I don't have the mesh floor, but you do notice the wind noise is there is a cross wind.

We have an Ironman steel roofrack with a mesh floor and side awning on our LC200, that does create some wind noise, but the amount of noise  seems to vary depending on various factors, e.g, what's on the rack, maybe wind direction. Ironman don't make a wind deflector so can't comment on if one would help. After a while driving we don't really notice the noise as much anyway, and our music is often being played quite loud!

We remove the roof rack when not needed! I'm the main driver of the car and don't necessarily like it being on between trips. Saying that, we don't camp every second weekend - if we did, I guess it would stay on!

We have our rack hanging by chain off the roof of the shed, attached to a (boat)? hand winch and pulley system. When needed, line the car up underneath, place a couple of foam pool noodles on the roof (just in case) and slowly lower the rack, do up the bolts, pull out the noodles...done by one person in a matter of minutes. Reverse procedure when removing.

Works for us, but as I said, we prefer not to leave it on for normal driving,  I wonder if you left it on all the time you would just get used to the noise and not notice it at all! We did a three week road trip  and it certainly seemed louder at the start than at the end!

Usually it's the mesh floor that causes the noise. Try cable tying a piece of plywood to the floor and see if that shuts it up.

our rack has a tin plate under the front of the rack approx 500 mm x the width of the rack to stop wind noise...seems to work

Read somewhere that a bloke put a peice of poly pipe across the front of his to carry the fishin' rods, and suddenly all the wind noise stopped! Or got a lot quieter anyway.  ;D  You could just cable tie a piece across the front and go for a burn and see if there's any difference before you commit to anything.

When I first fitted my roof rack (a 2.2m X 1.2m basket with mesh floor on 3 Rhino bars) the wind noise was unbearable.

Interestingly, I found the "howling" noise to be worst when a side wind was present. I also found the Rhino bars were actually noisier without the roof basket!

I attached a home made aluminium wind deflector to the front of the basket and it has removed 99.9% of the noise.

As a comparison, my '97 Pajero is now quieter inside than our '98 Nissan Pulsar (at any speed, even with the roof rack on the Pajero!)

Hi,
   try winding some good quality fishing cord in a spiral along the cross bar. Make the spiral about 45 degrees.
It may (or may not) disturb the harmonics across the bar.


cheers

Thanks for all the ideas,
Taking the rack off is not an option as we use the side awning all the time.
Ill try the different ideas and see if it improves.
Maybe I should just fit a high flow twin exhaust so it drowns the wind noise out. >:D
I wonder if SWMBO will buy that one.

I spent a few hours googling this a couple of weeks ago. From the search results the most effective thing I found was:

Take a thin stretch cord (bungee type material). Tie it to one end of the front bar and wrap it repeatedly around the bar to the other end of the front bar (spaced about an inch per loop, working around anything attached to the rack) where you tie it tight. It will disrupt the airflow to break the noise.

So far all I have done is to wrap bungee cords around the front of the rack and over a cross bar, it seems to have had a beneficial effect. Now I've got to go and buy the stretch cord and see how that goes. I've got one problem though and that is there is a flat plate extending backward welded under the bottom of much of the front of the roof rack which makes it impossible to wrap it over this section.

Over the long weekend, we tried out our new roof rack (Black Widow Alloy) which has a wind deflector on it, we also used a Rhino roof rack bag - we thought it was pretty quiet, certainly a lot quieter than when we have the mud tyres on.

Though we learnt that if the roof rack bag is not full, it does flap around a bit.

I have a powerfull 4x4 (style) rack fitted to my patrol. I cant hear one bit of wind noise from it. Im unsure if its because i have muddies fitted, the flat mounting plate across the front of the bar or because my patrol is so slow i cant get enough speed up to generate wind noise.  ;D
I think that whilst the cord idea  may solve the problem, why should you have too? Id be pissed if it were me...
My muddies arent that noisy yet either? How different is the shape of the arb rack compared to the powerful one?

I dunno maybe im just harder of hearing than i first though lol.

I have a windcheetah roof rack and it use to be on the Prado. Never had a problem with wind noise. I mounted the rack on the 76 series and the howling drove us mad. On the way to BrisVegas we had to stop at Albury and leave it at cousins. The legs are not for the 76 so I am going to buy 76 legs for it and see if there is a difference.

I fitted a full width LED light bar to mine, that stopped the wind traveling underneath, hence no noise!
