Service tire monitoring came on on my 2004 chevy 1500 silverado how do i fix this. i didnt think my truck had this

yes it could or ball joints

ck. the u joint

sounds to me either the tires are out of balance or maybe a belt has broken in one or more of your tires

COULD HAVE WRONG TIRE SIZE ON THE REAR,THE SPEED SENSOR COULD GONE BAD ( LOC. AT TRANS WHERE CABLE CONNECTS INTO)

If the tires were the exact size the problem would not be there. Replace the sensor to the size tires or replace the tires back to the same size it was before

tire rub...worn bearings.....bad bushing....manly though is larger tires rubbing

chevrolet usually resets itself after the problem is fixed. unless it is a bad sensor on one of the wheels. also check the spare some spares have a monitor in them.

it should be a long flathead screw driver inbetween rear bumper and tailgate

just have someone look at it. like aamco or someone that does a free diagnostic. the tranny will probably have to be rebuilt.

32 psiis actually low for a 3500. I have a 1500 silverado that runs 44 psi cold. The tire inflation monitor , monitors inflated cirunference. Sooooo, If it isn'nt round enough, it will let you know. Driving warms up both the air and the tire,off course changing everything again. Pressure is up and tire is bigger. Ask me not how it can tell what is going on with the tire sitting still. I'm only on page 9,000, the answer is here somewher. :-) Well good luck. I do know the above is accurate._Ned_
