I found out that my valve stem is leaking down around the area where it goes into the Tire.

What is the correct fix? I know I can buy a whole new TMPS, but is there an option for just replacing the stem? I looked at Rockauto and saw a number of different types of STEMS. Some look like a press in, while others are screw in.

What is the factory setup? Is there a nut in there that I can just tighten up to stop the leak?

If its just a stem replace, can a Wal-mart or local garage do this, or do I have to go the the dealer? I just recently got new tires, so I'd rather not have to pay for the mounting and balancing again if I can avoid that.

Discount tire does free flat repairs. That includes balancing and an internal tpms rebuild. I'd give them a shot first, unless it's the actual stem leaking.

Check and make sure the Schrader valve is snug too.

It's not the tire, I have confirmed it is stem. Stem at the tire, not the valve.

I'm 99% sure that the factory valve stems are not serviceable, but you could always call the dealer to confirm.

Aftermarket stems come in rubber or metal and a majority are serviceable. I know Dorman is; they showed a rebuild kit when I bought replacement sensors, but they aren't interchangeable with OEM.

If you're certain they are the factory sensors, you'll probably have to replace the whole shot.

If you recently bought tires, id take it back to the tire shop and tell them your tire keeps going flat. They may have tweaked something when mounting your new tires.

Some time ago I had a really slow leak in one tire. finally found the bad guy in the tread causing it. Went to Americas Tire/Discount tires . They fixed the leak, replaced the black rubber valve stem assy (done every time a flat is fixed or tire replaced at their store) TPMS version or not, then re-balanced that tire for zero $s. Based on what I believe I saw in the packaging, the only original part still in the wheel was the sensor. At some tire or garage locations, it wouldn't surprise me that *they* would ignore that all important function, whether it be a flat or tire replace.

Since, you are sure it is the valve stem, then it can be replaced separately. However, you will need a valve stem specifically made for TPMS sensors. There will be a small protrusion extending from the base of the stem where the screw for the sensor attaches to the valve stem. Most auto part places should have them in stock.

The stem is serviceable. There is a screw (T10, I believe) that holds the sensor to the stem. Remove it and the sensor, cut the bottom of the stem off with a razor blade and pull it through.

I can get a part # at work today if you like?

As stated, the valve is "serviceable", but for the price of a new one, replacement is much simpler so I figured why bother.
