Lampwick Posted August 9, 2014 Report Share Posted August 9, 2014 The roof rack on my Dispatch has always had a bit of a "hum" at around 45/50 mph with my triple ladder on but I could cope with it. I recently fitted a lockable tube and the noise is ridiculous at 50 upwards! Now other than never going above 50 or taking them off (beating the funny xxxxx) do any of you have any ideas as to stopping it? I was thinking of some sort of deflector?

andypaint Posted August 9, 2014 Report Share Posted August 9, 2014 Your not legally supposed to be going above 50mph in a commercial vehicle on roads unless on motorway. So problem solved! Quote Link to comment Share on other sites More sharing options...

silver pigeon69 Posted August 9, 2014 Report Share Posted August 9, 2014 Have a look and try to seal any gaps between the tube and the roofrack with gaffa tape. IMO The noise comes from the air being forced through small gaps. Quote Link to comment Share on other sites More sharing options...

NickS Posted August 10, 2014 Report Share Posted August 10, 2014 I had a whining noise from my roof box as soon as I went above about 15mph. I solved it by letting my mother in law travel inside. Quote Link to comment Share on other sites More sharing options...
