Good clarification. That said, the point I was trying to make and did not do very clearly is that I don't think 10 airbags is necessarily better than 8, sold front axles included.

10+ years ago I looked at a F or maybe S bare chassis with IFS. I counted 16 additional pivots/moving parts over a solid axle... no thanks. I believe someone has put the steering gear box in the middle of the IFS reducing the count by 5. so only 11additional...still no thanks. The good news is most will never put enough miles to where the additional parts will need replacing.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

On the bold part above, that kind of makes it a complete non-issue then, doesn't it? [emoticon]

Are you are advocating for a solid steer axles vs. IFS because of fewer moving parts? I am old enough to remember solid front axles on the Dodge M-series chassis as well as the Rockwell front axle used on vintage Newells and I believe on older Prevosts.

On the bigger coaches of the mid-to-late 1970s (like a 1976 Executive) with the Dodge chassis, unless an aftermarket Positrol spring-loaded front suspension stabilizer was added, crossing railroad tracks often induced a front end shimmy that required stopping and starting again. The Rockwell axles axles required the bearing to be repacked on a scheduled basis. After Rockwell went to oiled front axle bearings, oil would seep out in hot weather at highway speeds, never enough to cause a mechanical issue but unsightly to be sure.

The IFS systems were much more maintenance free right from their introduction on motorhomes, they ride and steer better, and they allow for a greater steering cut angle for a shorter turning radius. The next steps include computer controlled active suspension, active tag axle steering, and Dana electric column drive steering. But as I recall, this thread started with the search for a great used coach, so that last good stuff may have to wait.
