I have my front Firestone air bags at the top of their travel to insert my stands to block the coach while I rebuild the 6-pack (my leak tester says the 6-pack is leaking). The two bags on the passenger side and the rear bag on the driver side have extended to 13.25 inches. The front bag on the driver side is only at 12.25 inches, one inch less. This is after holding the front up arrow several times for a while and not seeing any noticable change of height
Any ideas on what is going on?
Assuming the bag itself is not leaking, maybe that is the valve that is leaking, or it's leaking faster than the others?
No, quite likely nothing is wrong. Remember in front only ONE ride height valve. So left/right very rarely read the same dimension for ride height.
Quite possible the rear ride height was off left/right, throwing the front off side to side.
Thank you both, especailly Brett. The leaking is causng the passenger side to sag, not the driver side. So, I will not worry with this and proceed on the 6-pack rebuild.
FWIW, I just opened the aux tank drain and got a shower. Wish the air dryer on aux compressor worked better. Plus I need to move the drain valves from the bottom of the brake and aux tank to the side of the coach so I can drain without having to be under the coach.
Wilkinson air dryer filled with 100% silica kitty litter works amazing . also Brett is correct I have a 1 inch offset side to side 2002 U270 you can adjust the rear ride height valves to get a quarter offset
John, I see a number of Wilkinson dryers, several with the same cup as in your picture. Could please share the model number?
Unfortunately I am not near my motorhome at this time. I did at one time post the actual number. I purchased off of eBay for $80

Just by a strange chance, you don't have an odd ball shock under there that wont extend as far as your others? I just changed my front shocks, koni golds. It had a red koni and a yellow Monroe on it. I thought that was really strange. I put an adsp air drier on my coach a couple years ago. It seems to be doing its job, no tank moisture to speak of. Do a google of adsp air drier, I got mine in town at a big truck store.
Thanks Craneman. Ebay, $99 open box with scratches. ZORO, New $202.31
MT Ted, My shocks are nearly new Koni Gold FSDs. Thanks for the reply
Also new with the silica from the same seller for 139.99
