vibration noise from towing mirror straps

I used the wool seatbelt covers over the it seemed to work. I did this on the patrol and the 76 series cruiser and now do it on our 200.

To stop straps from giving the wind vibration hum when holding down surfboards etc on the roofrack I put one twist in the strap and it eliminates it. I have not seen your setup but imagine it is the same thing.
Give it a try

Troopie,
I use the same mirrors on my Troopy and don't get the same problem. I bought some magnetic sign material from a sign writer and have strips of that under the belts, this stops any vibration or scuffing of the paint work. Used the Aussie truck mirrors for a number of years and there are no marks on my doors.

Have a good one

I gave those type of towing mirrors the flick years ago. I found that all that type were unstable and in some cases damaged the body paintwork.
I now use convex mirrors attached to the roo bar and a rear view camara.
I made the brackets for the mirrors myself so you cannot buy them.

Try an empty stubbie holder on the strap halfway down the door

I had the same vibration problem with my mirror straps - wondered what was wrong with the vehicle the first time it happened!
Sorted it out by using a small pad of foam jammed under the strap the first trip, but that dislodged when I got a gust (or blast) of wind from a truck going the other way.
Now I use a short piece of foam tubing (type used to insulate hot water pipes) that is held in place by a velcro strap - the velcro goes through the hole in the foam tube and wraps around the strap so it cannot come off or dislodge.
Anything that you can jam under the strap about midway along a free length of strap should dampen the vibration - it doesn't take much to change the resonant frequency.

To prevent marking of the paintwork where mirror legs contact the vehicle, I use a patch of 'contact' film (the adhesive-backed clear film used for covering books etc.) and remember to wipe off all dirt and dust before installing the mirror. If the contact film deteriorates and needs to be replaced, soften it with a hair dryer and it comes off easily.

cheers,

Shift the buckle on the strap either higher or lower and try it.

On the 100ser the best place for it is over the plastic strip that runs along the doors Keeps the straps off the paint and doesnt vibrate.

Had the same trouble with a Patrol but funnily only the left one did it.

Altered where the buckle was and it stopped

We had the same problem with noise from the passengers side mirror. Like you tried many things to rectify it, tightening the strap etc. Finally solved the problem by moving the towing mirror away from the vehicle mirror. It seemed that if the towing mirror was too close to the vehicle mirror it created turbulance that caused the vibration and noise. This worked for us, hope it works for you.

half a twist, stubbie holders etc all require you to dismantle and re-spool the strap to put it on.

Try putting a small cable tie round the strap where it is away from the paintwork, and tightening it just enough to put a curve in the width of the strap.
Doesn't affect the tension, and works a treat.

Easy peasy.

Thanks guys and gals. Now I have lots of ideas to test, the cable tie trick sounds too easy - I had some on board but it never occurred to me to try them.

As somebody else had experienced, at first I thought I had a major door problem (on a new car!) before I figured out it were the mirror straps. Strangely, its also the passenger side straps that are the loudest, might have to do with the proximity of the two mirrors - thanks for pointing that one out.

Hopefully I can enjoy a quiet tow next time the boat comes along for the trip.
