Tightening valve stem tip

While checking over my truck yesterday, my one steer tire was 5 lbs low on air. so I wondered if it was just the temp change or if I had a leak. after checking the other side, I knew I had a small leak. found it around the valve stem where it attaches to the rim. I tightened it up & good to go. today I was thinking I have done this before on my inner trailer tire about 3 months ago, after calling my local shop & them telling me there were no way to tighten without taking outer wheel off. I figured out a way, which may not be new, however I never heard or seen of this before. so since I have a new phone capable of videoing, I would try to make a short video on how this is done. for those who never knew it could be done & save someone some unneeded cost & downtime. it took me 45 min just to figure out getting the video to the computer. so this may be my last video for a while. o.k. I am trying to now figure out how to post video on here?

 

never knew there was a valve stem toll, that could tighten inside wheel valve stem. have any pic's ? name of tool or place to buy ?

 

I am talking about tightening the valve stem, not the inner core

O.K this is my first video. will do better next time. I have fixed this type leak more times than I can count. after time & bouncing, vibrating, they do come lose, or maybe the rubber seal shrinks. I don't know. this video only shows the valve on the steer tire being fixed but the same technique is used on any tire, any position.. you could also use the 9/16 crow foot & a 3/8 by 1/4 reducer & then use 1/4 socket & extensions if needed to give you more flexibility. I have always used the 3/8, but I have used 3 swivels before too. I have all steel rims. other type rims may be different & may need other methods. this is just something I taught myself & hope it can help someone, or they can tell some one & help someone.
