One problem related to rear air suspension springs has been reported for the 1998 Ford F-250. The most recently reported issues are listed below.
I have a 1998 F-250 light duty pickup with rear air bag suspension. The air bags have failed 3 times in the last 18 months. I was hoping there was a recall or something from Ford to fix this problem, I am getting tired of replacing these things at $500 a piece.
