I received my order of the above and 3 of the actual ride height valve assemblies. Above is just what you see. The black rubber cover is also on the new valve 90555105 by HALDEX.
Finditparts has discounts on a regular cycle. Hold off for the black friday discount. It's not listed yet. I used the Halloween discount of 15%. To make my purchases. Also a great place to get a D2 RKN18534 spare. Prices run from $14.00 up. They sell just about anything. Mark

We had a failure on the left rear wheel and we only noticed it while Kristi was following me to check for coolant leaks (another issue).  The top of the wheel well was riding on the tire.  We were glad this happened close to home.  I recommend carrying a spare in case you have an issue on the road - even with tow insurance, no one likes to be stuck in a shop waiting for a part to arrive at a premium price.  It would be interesting to know what percentage of 20 year old coaches have had to do a replacement - is it inevitable?

No reason this should be a show stopper for long or a reason for a tow or an expensive road call even without a spare. Everyone should know the workaround on there rig to get back into travel ride height without a functioning valve within minutes. For my coach and most others here it involves just manually raising coach to proper ride height and pulling the 7 amp travel mode fuse in the HWH control box. Good to go for unlimited amount of time and miles, checking once in awhile for proper ride height.

All three of my OEM valves have failed internally in the same manner in the last few years. Yes, possibly age-related, I don't think my driving habits are any different than others or the roads traveled.

Good info.  Where is the HWH control box?

Mounted in one of the compartments underneath most likely on the driver side.

DayDreamer,

Yours could be mounted on the ceiling of the basement behind (that is to the center of the coach) the inverter/converter.

If it's mechanical it will fail sooner or later, that' s guaranteed. Think about how many times it has had to make adjustments in 20 years. Hundreds of thousands ? Maybe a million. I carry a spare and actually have plans to replace all three proactively. in the meantime I have 3 levers on the floor next to the driver seat hooked to real honest to god cables to adjust ( level ) height when parked. Not as whiz bang as the one button push method but it works and if I have to I can adjust height with vise grips. Something to be said for simplicity. The coach is old school, but then again, so am I.

I have a 2003 u320 and my new ride height valve isn't raising after install. We replace both sides however the drivers side is not cooperating. Any suggestions would be appreciated.

Thank you!

You know the round part on the valve that has 4 holes, where you slide the linkage into? One of those holes has a plastic triangle marker near it. Make sure your linkage is going into the hole with the triangle.

One other thought is make sure that you didn't install the linkage upside down or said another way 180* out. This has happened to someone real close to me that wasn't paying attention. For sure refer to what Elliott posted.

I ordered Haldex #90555105. It says without dump valve. Is that correct part?
