Speedo Intermittent

[ruahic2]

Hi guys, my speedo has been acting up for a couple months now. This evening didn't work at all on the way home. I also have a noise in the truck-started out like brake wear indicator squeal but I pulled all wheels, brakes are fine. I am wondering about wheel speed sensors since they are built into the hub & bearings. I can hear a metallic noise while driving beside divider wall on interstates, but not grinding like wheel bearing. Any ideas or experiences with similar scenario? Thanks for any input!!!

your speedometer is faulty. it's a common problem on 2003-2006 silverados, particularly the SS. it was a factory recall. i believe GM sent letter saying that they were gonna recall ALL the silverados produced in that three year span..anyway it happened to me once before and i had it replaced under warranty. the stepper motor that moves the needle in the speedo guage is known to malfunction. All Silverado's are covered 7/70 on the speedometer, take yours to the dealer and they'll replace it.

He's right, GM issue'd a special policy extending the warrenty on the clusters for 03-04 Silverado's. The problem is common and even more common when it's cold outside.

too bad I got my letter after I already had 70K on the ss. Mine acts up in cold weather. Needle doesn't go down fast enough so when I speed up it says I'm going like 80 when I'm only going 50 mph.

Thanks for the info-I will roll over 100k this morning. I'll have to call a friend of mine at the dealer to check on recall. I really appreciate your reply.

Still could be a wheel bearing. A bad wheel bering won't always cause a groan/grinding noise. Check to make sure you do not have warped brake rotors which are contacting the pads when you drive. Also check the heat/dust shield on the hub, if it gets bent inwards, it can contact the rotor also.
