RE: TPMS - lock nuts on caps?

I don't want to fool around with extension tubes. I was able to reach in through the gaps in my hubs to attach the sensor caps without the jam nuts.

RE: TPMS - lock nuts on caps?

This is the unit: https://smile.amazon.com/gp/product/B07QNV8T31 You will have to watch their little video to see the nuts (more properly "jam nuts"). It's at the 4:38 mark. Basically, you thread a small nut onto the valve stem, then screw on the sensor cap, then use a wrench to back off the jam nut until it binds against the bottom of the sensor cap. This locks the nut and sensor to the stem. In order to remove the sensor cap, you must first loosen the jam nut with a wrench. On my rear dualies, it's impossible to get a wrench (or your hand) through the wheel cutout to work a wrench against the jam nut. I thought about going to a tire shop and having them unmount the outside wheel and install the sensor on the inside and then put it all back together, but then if I ever need to add air I can't as I can't remove the sensor. Based on what I'm reading here the jam nut is just anti-theft so today I'm going to install the caps with no jam nuts. https://en.wikipedia.org/wiki/Jam_nut

RE: TPMS - lock nuts on caps?

OK the consensus seems to be these are just anti-theft to make them difficult to remove without a tool. I'm going to ditch the lock nuts. I don't think these things are high-theft. The entire unit with 6 sensors only cost about $120 or so.

TPMS - lock nuts on caps?

I purchased a TPMS system for my RV. The sensors are screw-on caps. Not flow-through. When you install them, they come with a lock nut you are to tighten up against the sensor cap. The problem here is on my dualies I cannot get a wrench in there to secure the lock nut. The other problem is you can't add air while the cap is in place, so it would be impossible to remove the inner dually sensors to ever add air if needed. Is the lock nut really needed? Is this an anti-theft mechanism or is there an actual danger of the cap unscrewing? Worst case is I guess you lose a cap, or it loosens and you slowly leak air (which you would then detect).

RE: levelers

We like our levelers for more than just the ease of leveling. The stability they provide so we're not rocking and rolling when one of us moves around is also important to us. We park on too many sites that require significant leveling with little option for moving around to find a level spot to want to go back to blocks for leveling. We did that years ago with a 21' Class C, but never again... I agree. To me, the biggest benefit to leveling jacks is that the coach becomes rock-solid when they are down. No bouncing around on the suspension!
