my HCV's are all new a year ago,i adjusted my ride height on friday,raising the coach up soem.
i have one valve thats a little lazy,slow to react.

Al,i have no idea how it can be the steer axle doing this,if its been welded in place.
You do have a lot of tail wagging the dog with that bike hanging off the back.
maybe take the bike off and go for a drive?
Thats a lot of weight up high,and hanging off the back.
Balance is a great thing.

Randy , I must say I did start to think about the bike and all the weight she adds on the rear. as to the tag , my tag in in the reverse position and those air bags do line up on a angle .
Ed W pointed this out while over his pit some time back .

The problem is that with weight shift the drop will also shift. I agree at this point nothing more than a thorough inspection will be needed to get to the bottom of this leveling issue .

Javier and I talked a bit about your suspension when he was working on my Bus just before we pulled out in June..... He did not have a lot of good things to say about it.... in comparison to my WB..... I though I do not know How much He could do about it......

Al do I remember correctly your saying you fix the lean by dumping air and airing up again? The cause could not possibly be this simple since so many have looked at it, but if a rod to one of the HCV's was slipping, the results would be the same.

When I had my 2000, I had this priblem. However, coachworx fixed it by putting something on the set screw to keep it tight and would not allow it to back out. The problem was always the drivers side rear leveling rod.

It is a 2000 thing

Al if you have a bike lift with a lot of weight hanging back there, could be part of your problem. The tag bags do not assist in balance as they are tied together just like your font axle, but they are served by a pressure regulator instead of a leveling valve. I know my aux compressor will not lift the back of my coach without the tag, so pressure has to be well over a hundred. More weight could push the pressure even higher.

is it possible the tags are over inflating causing the problem?
Or the ride height of the drives set too low?

Mallie has it.
When i decreased the tag axle pressure my coach drove way better.
So,i decided to increase the drive axle pressure to see what happened.
Just did it yesterday.
I raised the ride height on the drives by 7/8''.
Then i raised the tag pressure back to 70psi.
I am now very happy with my coachs driveability.

I still think i can make it better,but thats just me.
The coach was fine for the PO.
But i'm a chassis guy,i like to fine tune my chassis.

So,Al.
what i would do is raise the drive axle ride height to 8 7/8''.
then drive it,
you said once to me your tag pressure was 90?

Also.
with the exception of the steering tag axle the rest of the suspension is the same as the WB's.
except the drive axle shocks are mounted inboard of the air bags,and the WB has them mounted outboard.
So i have no idea what J. is seeing under your coach.

In my quest to make my coach drive better i have spent many hours under it,and under a couple of WB's i have in the boneyard.
My next trick is to move my shock mounts out board,i have the mounts i need,right there in the back yard.

All.
Heres my take on dropping the air pressure on the tag.
When you decrease air pressure on the tag the drive axle takes more load,so the HCV automatically increases pressure to the drive bags.
Decreasing the load on the tag.

When i did that (in a walmart parking lot,300 miles from home) the coach drove way better,all the way home.
Carol could even feel the diff.

As Mallie said,the tag pressures are controlled by a regulator.
If the drive axle bags don't have enough load on them the tag takes over,since the tag bags are tied together they can cause the coach to lean.

One thing i remember from grade school science class was this:
The teacher had 2 balloons and a short glass tube.
He blew up one balloon almost full.
he blew up the 2nd balloon less than halfway.
he slipped the glass tube into the balloons and released the balloons.
He had been pinching off the balloons air with his fingers.

so,we have 2 balloons connected by a tube,one balloon halfway inflated,the other almost fully inflated.
I was sure the balloons would equalize,both being the same size.
But,they didn't equalize.
The biggest balloon got bigger,the smaller balloon got smaller.

Reason?
The small balloon had more resistance because it was not stretched out,the big balloon was easy to stretch out,the rubber was thinner.

Now,the airbags don't stretch,i'm sure of that,but you get the picture.
The tag bags are acting just like the balloons.
