Just purchased 2002 Workhorse P30; front airbag question

I just bought a 2002 Winnebago Sightseer 27c on a P30 Workhorse chassis.

I just drove it from Elkhart IN yesterday. It kept drifting to the right. i discovered the passenger side airbag was 0 and the driver's side was 40. I'm guessing a handling improvement is on the horizon. I will probably have to change the airbags. Not a big deal.

Searches indicate that the proper airbag pressure is determined by a 2 inch distance between the bumpstop and what it contacts. Looking under the front it looks like there are 2 bumpstops. Do I measure the upper or the lower bumpstop?

Does anyone have any experience with setting the front bag air pressure on this thing? I need to get this set before I move to an alignment. Apparently the airbag pressure change changes the alignment.

I also plan on upgrading the sway bar and bushings. Does anyone have any suggestions? Anyone use this? It would save $200 over a Roadmaster.

  • Cupping on front tires is many times bad shocks.
    Michelins? No and now way!
    What number follows P3 in vin?
  • Thanks. I ran the VIN number and it shows P-30. It looks like the chassis must be closely related. I'm going to cut a straw 2" and measure between the bumpstop and what it impacts on the lower bumpstop, then have it aligned. I'll assess the situation and determine whether an improvement in the sway bar is necessary.

    I'll also have them check the bell cranks for play.

    I was checking the front tires. There are bumps evenly spaced on the edge of the tread of both tires. Chinabombs. I'm lucky I made it home. Michelin XPS RIB?
  • The recommended minimum pressure is 55 lbs. I recommend starting at 70 lbs. and adjust up or down.
    To get the ride height corrected, raise the front of the coach so the suspension is fully extended and inflate both bags to 100-110 lbs. The reason for doing this is to fully expand the bags. Lower the coach and adjust the pressure to the desired level.
    The height is checked by measuring vertically from the top of the lower rubber bump stop.
    Your chassis would be a P32.
    No need to replace the springs unless the have collapsed.
  • Replace the factory coil springs with ones like this, designed for your front end weight. Does away with air bags.

    Check the bell cranks for play. Replace with tyhese.
