2018 KW T680 front end squeaks when going over bumps

CK. the hood 1st you can put some grease on the stops that are up by windshield, l guess you have all/ready greased the ft. end in all the grease fitting?

 

The air ride cab means that the hood will squeak at the place where the hood sits on near the top of firewall every time the cab moves.

 

A bit of white lithium grease on the rubber stops for the hood is a simple way to stop most squeaks that are not suspension produced but seem to be because the hood funnels the high frequency sound down.

 

Forget the grease on the rubber like few have mentioned, you’ll get grease on yourself when cleaning the windshield. I use old socks. I cut them out and slip them over the 2 rubbers. That stops the squeaky noise you hear.

 

Grease the 5th wheel lately?
Sometimes that puts the front end under stress and squeak/pop.
