Ride Height Valves

There has been some recent discussion here about these valves.
How do you recognize that you need one. Since I purchased this coach used, what are the signs for a replacement? Thanks

Barney, It is usually a good idea to replace all of the ride height valves at the same time. I had replaced the left rear valve several years ago when it failed on us on the way down from Silveton, CO to Montrose, CO riding on the rear tire. I was lucky to find a mechanic in Montrose who juryrigged an air hose to the top of the left rea airbag and ran it to the rear of the coach so I couls adjust the height until I was able to get home in Louisville, CO. I called ahead to the shop that works on our coach and had them order one.
When I just had new shock put on by Premier MCS in Tucson I had all three replaced. When they took off the old ride height valve their were three different types of valves, go figure. They cost me $202 each.

Dave,

I checked my ride height and found the rear to be 1/2" low on both sides. I made the same adjustment to both rear valves and the right side came up as expected, the left side did not change. The valve may not be dead yet but it doesn't appear to be working as it should.
I have 53k miles on the coach and it sounds like that my be a lot for the valves according to others that have had problems.

I have the same question as Dave. When we park our coach and level it within a day or so one side drops down and I was wondering if this was an indication that the valves might need to be replaced.

When you are using the leveling system while parked , the ride height valves are not operational. Your HWH system controls the air in the bag to keep you level. The HWH checks level every half hour or so and then adjusts the pressure to the appropriate bag. Don't know the age of the coaches involved , as many post just the serial number and that doesn't mean anything to me. If you are losing height , while parked overnight, it is the leveling system problem and NOT the ride height valves. I would guess you have an air leak somewhere

My understanding is that the air leveling is independent of the ride height. Once you hit D and let the brakes go the ride height takes over.
This came from the folks at HWH. We had a front ride height valve replaced at the HWH factory. (HWH doesn't do this work but an outside tech will come there and do it for you).
Our front valve failed over a period of about 2 years until we had no suspension in the front going up the road. Air leveling worked just fine.

Ron I Know your correct as I was told years back a friend on his CC Magna, Just pull a fuse to get you to a service shop and the said ride hight control in only when driving on the road and not part of Parking level. His coach was a 2000 Magna with a C-10 Cat. CC Fixed him up back then at a CC Rally. Ken 99 Allure 30356

Most if not all leveling systems bypass the ride height valves. If the coach drops after being leveled when parked there is most likely a leak from the selector valve(s) (ride height or level) or the level system compressor is not functioning. If you park and do not level and the coach drops a corner it could be the ride height valves or something else leaking. The ride height valves are basically the same as used in most OTR trucks, they do not fail that often, but they do fail. In most coaches failures can appear to be more frequent due to lack of use. Especially as compared to a truck that runs every day.

We had a bad air leak somewhere that was allowing our backend to loose all the air when parked. We could hear it leaking but could not figure where it was coming from. Someone said it could be the ride height valve. Well we took it into Premier RV in Junction City and Brian found that it was the ride height valve. Replaced it and it has not leaked since. We had owned the coach for five years and it had leaked most of that time, steadily getting worse. The escaping air made lots of weird noises too. Thanks again, Brian. We do live in our coach full-time so it gets a lot of use.

Does anyone know if there is a ride height valve in the front of a 2008 Magna? I just replaced the rubber linkage rod connectors on the to rear axle and have not been able to locate the front one.

Thanks,

Darwin the ride height valve in the front is located behind the generator. If you slide out the generator , you should see it on the wall in front of the fuel tank.
