DRW Valve Stem Extension Hose Installation Failure on 2012 F450
Well, as some have already read on my Facebook page, I picked up the new truck on Thursday from Classy Chassis in Valparaiso, IN. On Friday, in Elkhart, I had a company (Dually Depot) install Valve Stem Extension Hoses on the duals.
I had this done by my upfitter (Chariot) on my 2007 F550 and they worked great - never any trouble at all. But Tom Martin at Classy Chassis has never found a set that he really liked, so he couldn't help me on this for my 2012 F450.
The F550 has 19.5" wheels and the chrome plated plastic center hub cap covered the hub but not the lug nuts. So on the F550, the brackets that retain the end of the valve stem extension hoses were fixed to the lug nuts (under 2 of them I believe). Rock solid.
The 2012 F450 has 17" wheels and the chrome plated plastic center hub cap covers the hub and the lug nuts.
Where to mount the brackets?
To my surprise, they were screws to the plastic hub caps. Odd I thought. Odd was right
Somewhere between Indianapolis and Louisville, the hub cap spun out of control and "left the vehicle"! It took with it the hose for the outer dual. The hose for the inner dual was still connected and flailing around.
When the hose on the outer dual went orbital, it broke the valve stem. Looks like the core is missing too. Another motorist motioned/mouthed "flat tire". I pulled off and found the outer dual pretty much flat. Using the on-board air feature I had Classy Chassis install on the truck, I aired up the tire as best I could and used a valve cap from the extension hose from the inner dual. This helped the tire hold the air I put in it. I then removed the hose from the inner dual. I limped off I65 into some town into an industrial area and put the spare tire on.
This week, I plan to file a claim with the installer and go ahead and have my valve stem replaced and order another hub cap. Then swap the tires again.
Below are a couple of pictures. One is the completed project of having the valve stem extension hoses installed. Another is the wheel with the installation failed. The last is the spare installed.
