brave 33V and airbag

Dear friends,

I am living in The Netherlands and bought a Winnebago Brave 33V (model 2001) on a Workhorse chasis with some 15,000 miles on it in March 07.
The first year we have had a lot of problems but now (nearly) everything works well. The rig has 39,000 miles on its odometer now.
I like to have information on the following.

In September 2007 (20,000 miles) a have had a problem with my left front tire and I was advised to change (both) ball joints. After this repair ($ 1753) it worked well. This year in September (35,000 miles) I have changed all six tires and during that job the Good Year guy told me that my ball joints were 'loose'. In went immediately back to 'ball joint repair shop' and asked them to check these ball joints. They replied: "Nothing wrong with these ball joints, but you need to replace your airbags!" A $ 650 job.
The question is, I am not a technician - and my fluency in (technical) English is not as it should be - so I am not able to check what is really happening.
Could anybody advise me how I could check myself what is the real problem?

Thanks a lot

From what you describe you must have the "P" series chassis with coil springs on your front suspension.

This type of chassis generally came with rubber air bags inside both front coil springs as a suspension assist.

There should be air lines from each bag to a valve stem similar to the type on your tires. See if you can find these valves and check the pressure with a tire gauge. Average pressure for these bags is around 50 to 60psi.

If you have less that that add air to bring both bags up to 50 or 60psi, then after a couple of days or so recheck the pressure, if pressure remains the same then your bags are OK and don't need replacing.

If there's a significant drop in pressure then you either have a leaking valve or air bag and need to take the necessary action to replace the valve core if the leak is there or the bag if leak is from the bag.

Good luck and keep us posted on what you find,

Go to www.workhorse.com and download the chassis guide and you will find complete instructions for the P series chassis airbags. It may that the PO did not maintain the pressure properly. Just like tires the airbag pressure has to be checked and maintained on a regular basis.

brave airbag

Thank you Jim & Sherry for your quick and clear answer. This morning it was the first time I went under my motorhome and inspected the airbags. I tried to pump them but after a short time I have got the impression that bot of them are worn and leak. So I have to replace them.
Do you know what is a resonable price for that job, parts and labor?(I have got a quote of $ 650)
Thanks,

Wim
