A friend has an 04 3500 with steel wheels and has had at least 2 valve stems go on his truck.
He says they have a metal valve stem that attaches to the wheel with what looks like a rubber grommet which is where the leaks come from. He's still running the tires it came with, anyone know anything about this?

I did a seach, all I found was:

if they look like this, i have been running them in my wheeling rig for years with no problems, maybe they are not tight or the seals are shot

 

No, that's not the ones, he says his are pressed in or something?

 

My valve stems just started leaking, no warning. I drove from san antonio to laredo, when i got there ,one tire was low, I went to air it up and found the stem leaking, so i then checked the other <3> they to were leaking. I had all four replaced. they looked like a regular stem , not the one with the nut and seal. As I stated then you need to check the stems, as I only had about 4/5k miles. I was lucky they <stems> didn't blow out going down the highway 75 or so MPH. as it was very possible. I posted the thread then to try and help someone avoid a serious problem . as of today 6-12-06 istill say to check the stems THANKS; Grant
