I bought a set of these on ebay: Ford Genuine TPMS Sensors 2009 014 Set 4 DE8T 1A180 AA Brand New Take Offs | eBay
So how do they attach? Do they come with fasteners that screw directly to the rim?
They don't mount to the rim. As elyk864 showed in the picture, they screw onto the back of the shrader valve / stem.
The link he has is the same as OE mounting. Neither one is attached to the rim(The sensor itself). The sensors screw into the back of the valve. Then the valve is "popped" into the valve hole. So with new wheels you will need to get new valves, then attach your sensors to the back of the new valves using a new screw. You do not want to use the same screw as you can run the risk of it coming loose later. They torque down to a specific inch lbs setting.
So the valve stem holds the assembly into place on the rim and the TPMS sensor is held to the stem with a single screw. Otherwise no other attachment of the TMPS sensor to anything else.
You are correct.
Click on the link I gave you, it shows a picture of the sensor attached to the bottom of the valve; the ones I linked to come complete and at a very reasonable price. Ford charges more for one than the set I linked.
Great! What is confusing is when you look at the sensors from the end view it appears there are two eyelets where screws would go.......
They have nothing to do with fastening them to the wheels. You're good.
I appreciate the collective wisdom here. Too bad you all weren't in my my part of the world. Coffee and donuts for all!
No problem, I work in the tire and wheel industry. I have explained TPMS sensors thousands of times. :big smile:
