Alex fg Barra New Member 10 Member For: 3y 8m 2d Posted 15/10/20 08:26 AM Share Posted 15/10/20 08:26 AM Hey guys I have a 2011 mk1 manual Ute, it has a high pitched noise between 90-120 you can’t hear a thing until you hit 90, and it disappears complete at 120, it’s only noticeable when cruising at that speed, and it only happens when I’m accelerating, as soon as I take my foot off it disappears. as you can imagine it’s quite hard to diagnose a noise that only happens at highway speed any help would be greatly appreciated Link to comment Share on other sites More sharing options...

You could probably set it up on a hoist and replicate it by pushing up or pulling down on parts while the wheels are spinning in the air at the relevant speed.

I would be thinking that's something to do with the wheels/tyres, based on the noise. Link to comment Share on other sites More sharing options...
