You had showed that installing operation very nicely and clearly thanks.

THANK YOU. I learned so much. I’m goi g to do this job myself. You just saved me 2hr labor charge. God bless you sir.

GREAT video. Very detailed, great diagnosis, and Absolutely Fantastic repair. 👍

Excellent video. Couple suggestions. First of all, if this weren't a school bus you'd want to be even more careful about cribbing and not get under it or into any pinch zones with any air pressure in the auxiliary system. Otherwise the bus could crush you very quickly when disconnecting an air fitting or moving the leveling valve arm. Also, minor point but you'll be less likely to damage the brass fittings if you use flare nut wrenches instead of combination end wrenches. Overall, very nice video. Thanks!

I have a problem. My school bus is on the back side. I already changed shock absorber, air bags and there are no air leaks. One bag is higher than the other and the air regulator has no adjustment, any solution or why does that happen?

Is there only one leveling valve on the rear.

Intuitive！

Why not drain the air system at the tank drain? You could then use the air brake to vacate anything left in a can or other location. This would eliminate the wear and tear from the rapid pumping of the brake. Now my question: Can the leveling valve, or the air bags in another way, be modified to produce front to rear and/or side to side leveling to some degree?

You contradicted yourself three times on the air bag inflation and deflation?

That mounting bracket doesn’t look 👀 new…..😂🤣😝
