I've been reading a lot about sway issues on class a motorhomes on F-53 chassis and came across the cheap handling fix. I decided to try this but upon inspection both my sway bars only have one hole in the end. Is it fair to assume they have been replaced?
F53 chassis didn't get the extra hole until 1999. Your sway bares are OEM. Do check the center bushings on both front and rear. They are prone to early failure.
Skuterdude on Ebay has the best stuff. I can attest to his quality and service. Sway bar bushings for front and rear.
