FMTV . . .Replace Dust Boot for FREEPosted: 2015/19/05
Mechanics, the rubber dust boots that protect the FMTV’s cab ride height limit switch could be falling apart. Exposure to the elements can make these old-style boots dry rot.
A dry-rotted book doesn’t provide much protection. And that could lead to problems!
Whether the boot has started dry-rotting or not, you need to replace it. Remove the old boot by prying up its bottom edge. Then replace it with NSN 5930-01-642-8386 (PN 125321115). That gets a new-style boot that holds up to the elements better.
And if your truck qualifies, you can get a free boot by submitting a deficiency request form at:
This offer applies only to vehicles built between 11 Apr 12 and 28 Feb 15. And it expires February 2017. You’ll find the vehicle’s built-date info on the data plate inside the cab next to the driver’s knee.
