Help identifying Air Valve - Mib2nd - 09-23-2024
Working on the last air leak on the front of the coach and need some help identifying this part. It has a relief at the bottom leaking a slight amount of air.

Be aware when you replace that front height control valve. Newell uses a setup where the vertical arm is mounted to the sway bar. As the front end rises and falls the sway bar pivot. However the sway bar rotation is no where near the actual up and down movement of the front suspension.Therefore the arm is very short on the HCV to compensate for the lack of movement. It makes the adjustment of the valve VERY sensitive.
To complicate matters, the DANA IFS 84 suspension changes toe in of the front tires with a change in ride height.
Measure ride height carefully before you begin.
And always make sure you have adequate support for the coach before getting under there for any reason.

As Richard says its very sensitive, from a commercial standpoint those micro bubbles you see are not worth changing the valve out. You could buy a spare for when it actually fails. Air will be hissing out of the nut in the center where the arm connects to the rubber end, otherwise I'd leave it alone. If you wanna carry spare things though the rubber grommet top and bottom are common failure points. I would get 2 of each. Also get a few of the tiny hose clamps that hold it together. Just my 2 cents worth.

Sorry to side track this thread but I thought I would through a pitch for Carl he is a retired ice trucker in Alaska, he and I had a good discussion on what happens during on the road emergency's and what spare parts he carried as the driver is the mechanic also in most of Alaska. Like many truckers he's a fan of the series 60 and alison combo.
